gt1 dsc fault abs brake light

[bdriven]

Hi Folks,
my ABS DSC brake lights are on,
after hours of tinkering I was able to get this codes:

36 DSC: Inlet valve, front left
32 dsc: outlet valve, front left
35 dsc: inlet valve, front right

I believe these to be from wheel speed sensors,
but wanted to check if any of you guys had dealt with this before,
any bit of help HELPS !

Thanks!!!

i doubt that the valves are out of spec, and for the sensors, it would say sensors... can you test the sensors? do you have a multimeter with diode function? can you use the meter?

Thank you TX5, yes, I do have a MM, I'd to have to find out what to look for tho.....

[TerminatorX5]

if you can gain access to the ABS connector, test from there the speed sensors... do a search, there were very recent posts, within a week, talking about sensor testing...

good deal, thanks!

+1 on the sensor. Just replaced my wheel sensor after a scan informed me that the front driver side sensor was bad.

Could be a bad ABS pump, or ABS module.

EDIT: Nevermind. upallnight got me confused with this old thread. I see that you had a bad DSC module and replaced it to solve this problem. Please add to the first post and change the title to include SOLVED.

I don't understand why you don't just follow the test plan in DIS? Why guess?

Anyways, I'm not all that familiar with that but I wouldn't think sensors are not connected to the valves per se. I'm thinking there's something wrong in a module/pump/wiring.

Did you have any recent work done to the DSC/ABS module or near that area? I thought I read that the fittings/wiring to DSC/ABS module can be damaged easily if not paying attention.

Sorry for the confusion. I said that Terminator was probably correct in his assessment that it was probably not the wheel sensor that why I gave him the +1. When I had a bad wheel sensor, the scan actually said bad wheel sensor.

Valves are controlled by the module and if they don't send a respond back that they are open or close the computer will assume that the valve is bad.

The thread wasn't that old (1 month), and a resolution wasn't in the thread. One of my pet peeve is when people post a thread with a problem, but never post the solution or fix.

Yeah, I should have recognized his ID since we were helping him with the DSC module retrofit errors in the other thread. He should have just kept going on this thread.
