Transfer Case Actuator Replaced

Hi All,

Recently I replaced the Transfer Case Actuator as I had the Trifecta pf lights (and a mechanic told me it was the Actuator).

However the lights remain on.

I have cleared the codes using a C310+, but as soon as I start the car, the three lights come back on.

I read on this forum that I need to re-set the car for th enew resistor, but can't find anything on how to do this.

I also have the IPNA software running on a virtual machine on my laptop, and 3 OBD II cables, but when I try to use the software, I get a communication error?

How can I re-set the car to accept the new Actuator?

What error comes back? You need to confirm you didn't pick up a different fault that was masked from the actuator

Actuator replaced but you said recognize the resistor.

Did you put in a new classification resistor also? They are specifically paired by an acceptable range and can't be swapped willy-nilly (another don't ask what I did[emoji28])

Does the classification resistor pair with the transfer case or actuator?

What is a Classification Resistor? Is that part of the Actuator (the circuit board between the gear and the motor)?

With the transfer case

Yeah, found out what it is.

We re-used the one from the original Actuator.

Just replaced the whole actuator (Motor, circuit board and gear). It did not come with a resistor.

Do I need to change that also?
The error code is something about the resistor being faulty, but I thought that was because we had changed the Actuator.

The seller (on eBay) said "After installation you need to have it taught."

Not sure wehat that means.

This is the Classification Resistor https://uploads.tapatalk-cdn.com/202...52a426af60.jpg

Yes, I figured out what the Classification Resistor is.

Now my question is how to get the car to accept the new Actuator?

Do I need to change the Classification Resistor?

Again, how do I get the car to accept the new Classification Resistor?

Have you pulled the battery cables off and waited a few minutes to help clear codes?

If not start there, then if you've changed your transfer case oil do a oil service reset and scan again.
