If you aren't seeing any fault codes on dash IE
-66 or -68 then controller isn't reading fault
Check your motor cables if I remember correctly as you turn left the right motor moves forward and left motor moves in reverse a little
And vice versa there should be a fault code if pot is faulty it will show -11 or -10
If no faults check the wiring where the angle pot wires are
It does have a potentiometer, and it is actually, working correctly. Thats the first place I went. The LH motor changes direction when it should but the RH motor controller isn't even sending power to the drive motor at all. I checked the fuses and they're ok, unfortunately!
Lol
Any idea how I can verify the motor controller? It isn't producing and error codes and I swear that might be a clue to follow.
Thx,
I have seen a similar issue before on a TMG15 where the drive would hesitate when turning, and it turned out to be a worn steering angle sensor causing the controller to lose signal briefly in that range. It might be worth checking the sensor alignment and the wiring harness around the steer motor for any loose or corroded connections. Sometimes even a small break in the wire insulation can cause intermittent loss of power to one wheel. I also came across a helpful reference on a case study about signal drop under load that pointed to the same kind of fault. Has the dead spot been there since you got the truck, or did it start happening gradually?
On the steer wheel shaft (inside cover on top of steer shaft )there is either switches or potentiometer check there if it is a pot and I'm sure it is , pot on output will be less than 5 volts positive as it is turned and the other will be less than 5 volts negative make sure wiring is good to steer angle pot
It sounds as if it is in that area
