The VTM on my truck stopped working. The light is on solid and only front wheel drive is working.
This happened after a stormy day when there was alot of sticks on the road. Is there a chance that a wire got pulled off some where under the truck? I have been under there and didn’t see much but I didn’t really know what I was looking for.
Do this, read out the codes and go from there…
The VTM light means Variable Torque Management. Chances are there is a code or several codes in the computer causing this light to come on. To retrieve codes, ground the Brown wire in cavity #9 of the OBD-II connector and turn on the key on and the VTM-4 light should flash out the problem codes.
Or take it to a service place that can read the codes and repair what is wrong.
I read the codes because the “Service Engine” light (O2 Sensor) is also on but it didn’t show any codes for the VTM. So I will try the brown wire method.
Thank you
I suspect that the traction control is disabled because of the engine fault.
