And with an early build date...your IHKA control panel would have the REST button and not the MAX button. So, if you wanted to upgrade to the an IHKA w/MAX button...you would have to find a new or used one, then code your car so that it can run the extra programming (max cooling) feature. Your vehicle won't automatically perform the MAX function without reprogramming.

Below is an illustrated diagram of the manual IHKR control unit:

Thanks Qsilver. By reprogram the car you mean to do the module swap coding, not the actual NCS Expert 'aktiv' file change. I don't remember now but when I tried the module with the cracked screen and MAX feature, I did the swap with GT1 or SSS but I am not sure I tried the MAX though. I might have...

Now, I am trying to change these values but I cannot find the third one below.
Is this because I am missing some options on the car? What module was that supposed to be in?

Remember Recirculating Air Setting after shutdown
UMLUFT_MEMORY - default is nicht_activ

Independant Park Heating
STANDHEIZUNG - default is nicht_activ

Coolant Damping
KUEHLWASSER_DEDAEMPFUNG - default is 25_sekunden

this is in reference to the AC question...

The A11 module from 09-1999 to 09-2000 has 5 connectors and the newer A11 modules have 4 connectors. Extra connector X18153 (6-pin) from the older module has only one pin engaged, and that is the pin that seems to be the INDEPENDENT PARK HEATING CHECK VALVE. That pin has been moved to another connector (X610) on the newer modules, and the whole connector X18153 was eliminated - but the point is, there are same functions between the both, older and newer A11 modules...

I can not view SVG files at work, so I can't trace that pin on the schematics until I get home, to see if that signal goes to same locations on both, older and newer cars...

this one is reference to the lights operation - this write up refers to E38/E39 but still applies to E53:

Light check control module (LCM)


The light check control module combines the functions of the following control units previously installed individually in the E38:

• Light module
• Check-control module
• Manual beam throw control

As of production break 95, the light check control module replaces the light module and check control module control units in the E38 and will be installed in all E39 vehicles as of series launch.
Functions, general

Diagnosis as well as communication with other control units takes place via the I-bus (E38/E39 high) or K-bus (E39 basic).

In the event of the control unit or one of its peripheral elements failing, an emergency operation facility maintains following functions.

• The outer rear lights (no licence plate light) low beam light, are switched on at "terminal 15 ON" irrespective of the position of the light switch.
• The left and right brake lights are switched on at "terminal 15 ON" and the brake light switch operated.

No communication via the I-bus/K-bus, i.e. also no diagnosis, is possible in emergency mode.
If a trailer coupling is installed in the vehicle, the lamp circuits of the pulling vehicle with a trailer module must be disconnected from those of the trailer. The LCM is connected to the trailer module via a data link.
A diagnosis program is provided for all 3 function spheres of the LCM.
Light functions


The light check control module controls and monitors

• all external vehicle headlights and lamps both when switched on and switched off (cold and warm monitoring)
• all switches and buttons for light functions
• The functions of the dimmer for the instrument lights and locator lights

Components

With the exception of the brake light switch, all switches scanned by the LCM are designed such that they switch to ground.

The following switches are scanned by the LCM:

• Combined switch for parking light/low beam
• Turn signal/dip switch
• Fog light switch
• Brake light switch
• Hazard warning push-button
• Dimmer potentiometer for instrument locator lights

The LCM receives further information via the I-bus/K-bus.
Light switch
When the light switch is in rest position, all contacts are closed (R < 1 Ohm) and the corresponding contact is opened (R> 1 MOhm) in the low beam or high beam position.
The lighting for the light switch is controlled separately by the LCM. It lights at full brightness when the light switch is in the OFF position. It is dimmed to the same extent as the instrument and locator lights when they are switched on.
Brake light switch
The brake light switch is permanently monitored by the LCM when terminal R is activated.
It is designed as a Hall sensor and features 3 lines (terminal R, terminal 31, signal line). The test switch is not necessary.
Hazard warning switch
The indicator lamp for the hazard warning function is located in the hazard warning switch. It also serves as a locator light.
Dimmer potentiometer
The dimmed instrument, locator and function lights (terminal 58g) is activated when the light switch is in the parking light or low beam light position.
The voltage generated at terminal 58g is dependent on the position of the dimmer potentiometer.
Activation of indicator lamps in the instrument cluster
The indicator lamps for left turn signal indicator, right turn signal indicator, rear fog light, fog light and high beam located in the instrument cluster are activated via the I-Bus/K-bus.
Lights

The lamps of the vehicle lighting system are monitored both when switched off and switched on (cold and warm monitoring).
The lamps are activated by means of transistors. Due to the fact that they are now short-circuit-protected, the standard lamp fuses are no longer necessary.
The lamps can also be activated via the diagnosis function.
The country-specific functions of the lamp circuits are coded.
Check control functions

The task of the check control is to inform the driver. It provides him with information via the text display in the display unit of the IKE (E38/E39 high) or via the LC display field for check control messages in the instrument cluster (E39 basic) regarding failure of important functions as well as notes and warnings.
Common features of both wiring systems

The check control function in the LCM monitors its own sensors and detects when a message is necessary for these sensors. Consequently it sends a data telegram to the IKE/instrument cluster with the request to display the message text in the text display or the message in the display field for check control messages.

The following sensors are monitored:

• Thermal oil level sensor
• Brake fluid level switch
• Coolant level switch
• Wash water level switch

The LCM is additionally connected via a line to the EML and DDE control units.
An ignition lock and belt buckle contact is included in the US version.
In addition, it also receives LCM-internal messages concerning defective lamps.
Added to this, it evaluates messages from other control units which it receives via the I-bus and sends the corresponding request to the IKE/instrument cluster.

Vehicle system E38/E39 high

The messages are, in part, accompanied by an acoustic annunciator.
The gong in conjunction with check control messages is activated via the I-bus (no direct line link between the LCM and gong). It should be noted that depending on the importance and number of messages previously occurred an acoustic signal does not sound every time and also not for the same message.
The following check control text messages are possible in the E38/E39 high system:
Check engine oil level
The level is determined by a thermal oil level sensor.
It supplies a square-wave signal and receives voltage as of terminal 15.

Check brake fluid
Top up wash water
Check coolant level
Engine emergency program
If problems are detected at the throttle or at the pedal sensor, the EML assumes emergency mode, accompanied by a distinct reduction in engine performance. In this case, the check control receives a signal via a line, with which the LCM is connected directly to the EML, and outputs this message.
Preheating/injection systemg
The LCM is connected via a line to the DDE control unit, from which it receives a signal for the messages preheating and injection system.
EEPROM LCM
appears when the LCM is not coded.
Ignition key in lock (US only)
A switch connected to ground is located in the ignition lock. The display is shown when the driver's door is open until the ignition key is removed, however, only at "ignition OFF".
Buckle belt (US, Gulf States only)
The message appears when the seat belt has not been buckled (closed). The belt contact switch which switches to ground is connected directly to the LCM.
Information which the check control receives from the IKE/instrument cluster:
The check control receives information from the IKE for the following messages. Troubleshooting should be continued in the IKE if incorrect messages are received.
Transmission emergency program
If there is a defect in a transmission control unit to the IKE, the LCM is informed via the I-bus.
Release parking brake
This message appears on exceeding a speed of 5 km/h with the parking brake applied.
Check brake pad
Coolant temperature
Stop! Engine oil pressure

Information which the check control receives from the ZKE:
The check control receives information from the ZKE and processes it for the following messages. Troubleshooting should be continued in the ZKE if incorrect messages are received.
Door open
This message is output as of a speed of 5 km/h if the driver's, passenger's or rear door is open.
Luggage compartment (boot/trunk) open
This message appears on exceeding a speed of 5 km/h with the boot/trunk lid open.
Light on?
This indication appears in ignition lock position "0" when the driver's door is opened with the parking light switched on.

The LCM evaluates all light messages internally.
E39 basic system

On vehicles with the basic system, information is indicated not in the form of text messages but rather by warning lamps and symbols in the LC display field for check control messages in the instrument cluster.
The check control also requests indication for following lamps:
General brake warning lamp
This switch is activated by the LCM when its brake fluid level switch informs it that the brake fluid level is too low.
Wash water
This lamp lights when the switch connected to the LCM signals that the wash water level is too low.
Oil level indicator lamp
The oil level is determined by a thermal oil level sensor. It is connected directly to the LCM and supplies a square-wave signal with a frequency serving as a measure for the level. It receives its power supply as of terminal 15.
Preheating
The LCM is connected via a line link to the DDE control unit, from which it receives the signal to activate this lamp.
Seat belt indicator lamp
On US and Gulf State vehicles, this lamp lights as of "ignition ON" when the seat belt has not been buckled (closed). The belt contact switch which switches to ground is connected directly to the LCM.
Defective lamps (in the LC display for check control messages)
Door messages (in the LC display for check control messages)
Catalytic converter overheating (Japan version only)
Additionally: Gong with ignition key in lock (US version only)

Manual headlight beam throw control

If a manual headlight beam throw control facility is installed in the vehicle (identification feature): Knurled wheel for manual headlight beam throw control (on instrument panel) then this function is included in the LCM.
The LCM receives a voltage signal from the knurled wheel for manual headlight beam throw control and activates the motors in the headlights accordingly.
These motors are designed as stepper motors. They are connected in parallel. For this reason, although the electronic control can detect a short-circuit, it cannot detect a break in one of the two motors.
Adjustment via the knurled wheel is no longer possible in the case of fault.
The electronic control conducts a referencing run when the parking lights are switched on or when terminal 61 ("engine running") is activated.

so why don't you code off the parking light ambers and just use angel eyes as parking lights? i don't think you can get away from tail lights being on when the switch is in the parking light position

there are a couple of lines that relate to angel eye's as DRL's but i never gotten them to work. Its probably one of those combination codes that needs another line adjusted.

There is a small circuitry inside the switch that allows the LCM to monitor the switch for the position and based on that, turn on/off specific light. The lights in the car can be turned on/off by sending specific commands on the iBus, and you might create a special effects light show (first 30 seconds of this video BMW M7 - YouTube). Thus, it is possible to build a box that will intercept the signals coming from the light switch S8 and tell the LCM to behave in your specifically desired way.

good example is a little box that I have for the TV module, that blocks the speed signal coming to the TV module and tells the module the speed is zero, hence allowing the TV to stay on while the car is in motion.

So, the answer is - do you want to build such a box?

That would be the iLights module or whatever its called.....Im not interested in making a light show. I Was just curious as to what options (as far as custom coding individual lights) through the LCM were available to us.

Maybe I'm mistaken, but if the switch position is monitored as you said, and the lamp circuits are coded.....wouldn't that mean we're able to code light functions as we see fit? I know that relies on the assumption that we know which lines of code to change an how...

Call it the OCD in me that would irritate the heck out of me knowing the tail lights were on...lol

[jgold47]

you could try this code:

TAGFAHRLICHT_ECE : Daytime running lights(ECE)[angle eyes]

to aktiv

Try playing with these two

BLK_V_GED_ALS_SIDEMARK - this controls the functions of the side markers, but may turn everything off.
aktiv
BLK_V_GEDIMMT_ALS_ERSATZ
aktiv
BL_ALS_SL_DIMMEN - this should mabye turn off your brake lights as parking lights
aktiv


you could also turn on your high beams as DRL which is the normal

GED_FL_ALS_DRL


but then turn the intensity all the way down.
using

FL_DIMMUNG_ALS_DRL
wert_06

The problem is I cant figure out what wert_06 means (_01-05 I can find). FL_DIMMUNG_ALS_DRL :wert_01 = 0 % wert_02 = 18,82 % wert_03 = 20,39 % wert_04 = 43,92 %wert_05 = 18,82 % setting intensity of high beams for daytime running light

so maybe try wert_01 and see if the tagfarlict works for you.

I sort of had this set up yesterday and it didnt work, but I was having problems with the ALS turning on and that may have disrupted the normal DRL function.



Dennis -

SL_INNEN_ALS_TWL : parking light
SL_VORNE_ALS_ZUSATZ_BLK : front parking light as additional turn light

Both are set to nicht.

could be what we are looking for.

the problem is the stupid nomenclature keeps changing between the lights. One minute they are side markers, then parking lights, then SL (standlict), but then there are three distinct sets of SL's, SL_LH, SL_LHI and SL_LV (and then rights), which I guess is Stand licht (rear?), stand licht inner (rear) and standlicht (front) that can be hot and cold monitored. I guess we could isolate the code by pulling the bulb hot and seeing if hot monitoring picks it up. then start coding off hot monitoring till it goes away.

[SlickGT1]

Right I was looking at that too. This is what I came up with.

STANDLICHT = SL = PARKING LIGHTS

VORNE = AHEAD

INNEN = INNER

ALS - AS

The issue is I can't figure out what TWL stands for. I guess nothing left to do but try it.

LH = LEFT REAR
LHI = LEFT REAR INNER
LV = FRONT LEFT
RH = REAR RIGHT
RHI = REAR RIGHT INNER
RV = FRONT RIGHT.

So when the two are side by side, L = Left, V = Front, R = Right, H = Rear, I = Inner.

Now what about UEBERSPG_ABSCHALT_SL_H - nicht_activ on mine. I think this is Overvoltage OFF Parking light Rear

SL_VORNE_ALS_ZUSATZ_BLK - wouldn't this make the AE blink as turn signals?
SL_INNEN_ALS_TWL = This translates to Parklight inner as (TWL) WTF is TWL? I think we need to try this one first.


================================================== =======
Side note, my car FL_DIMMUNG_ALS_DRL is wert_06, my drls are off.
GED_FL_ALS_DRL is nicht_activ as well.
