Re: Rear E-Locker
 

TC 1 is standard
TC 2 allows wheel spin and keeps the brakes from slowing the spinning wheels for mud and snow.

I always used e locker and TC2 in 4 low so don't know if TC2 worked in HI lock or open.

I just don't want TC to slow the wheels down when u need the wheel spin and the e locker is going to keep the rear tires same speed so the TC won't slow one rear wheel if it's turning faster because it has a little less traction.

will the e locker work in 4 hi in the H3?

Re: Rear E-Locker
 

where is the traction control ? i know there is only a button for stabiliztrack on the control panel..

Re: Rear E-Locker
 

No. It will disengage at 20MPH.

So can you go over 20MPH in TC 1?

Re: Rear E-Locker
 

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

Where is it? In the puter:D

Re: Rear E-Locker
 

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?

Re: Rear E-Locker
 

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

Re: Rear E-Locker
 

On which model H2 or H3?

If H3, what switch are you referring to?

Re: Rear E-Locker
 

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).

Re: Rear E-Locker
 

That is the stabilitrac switch. Different system than the traction control.

You cannot turn off the traction control:D

Re: Rear E-Locker
 

You are incorrect sir/maam (;))... there is a switch on the column... the ignition switch! That will turn off the traction control. But I don't think it's useful over 5 mpg (I could be wrong;) )!

Sir????

Here are two pages from the owners manual. You can get the electronic owners manual from www.mygmlink.com after you register.

Re: Rear E-Locker
 

:popcorn: That sure explains it :clapping:

Re: Rear E-Locker
 

so lets see, we turn OFF the TC/SC when in mud and snow or it will limit wheel spin which may get u stuck.
Now the e locker kicks out over 20mph, so if play off road in muddy or snowy conditions we just have to keep the speedo under 20mph :twak:

I know I've hit a lot more than 20mph in mud pits and snow drifts not to mention slippery hills.


I still want my elocker to stay on when I turn it on.

***crickets****




now what?

Re: Rear E-Locker
 

:iagree:

Re: Rear E-Locker
 

I made the mistake of not getting the off-road package so I can't just try this on mine. How about this. With the key off, disconnect the connector from the e-locker. Measure the resistance from the black wire (going to the control not to the e-lock coil) to a good ground as close to the control as possible. Zero out the probe resistance first.

Re: Rear E-Locker
 

I have the service manual and pages 4-150, 4-156, 4-160 explain the following respectively: Differential lock schematics, Circuit Description, and Electronic Diff Lock Will Not Disengage troubleshooting. I wish I could post this and have it be readable or be able to explain it. (I'm a Pharmacist not an Electrical Engineer):confused: if anyone else can post this info for ChevyHighPerformance to look at we might have an answer.
