That is because the Traction Control system is always on. You cannot turn it off.

Where is it? In the puter

Wow, strong opinions either way - I don't know what the right answer is, but I will add it is very difficult to design a traction system for all surfaces.

The TC switch shuts off both the stability and traction systems.

There are two wires going to the e-locker: light green and black (I think these are the colors). +battery is switched to the light green wire and the black wire returns to the transfer case shift control module where it connects to ground through a resistor/current limiter. The final circuit will be pretty simple but you need to do serveral tests first to understand what is inside the control module.

For example, you'll need a diode to clamp the inductive current for the e-locker coil to prevent an insulation breakdown when you interrupt coil current.

TC Switch?

[ChevyHighPerformance]

Sorry, I wasn't clear - Traction Control System - TCS switch.

On which model H2 or H3?

If H3, what switch are you referring to?

[ChevyHighPerformance]

I was refering to the H3. This is the rightmost switch - picture of a car with squiggly lines underneath it. Hold it in for 5 sec and this will disable the traction control and the stability system (if you have it).
