Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Welcome to Just Answer Chrysler my name is Mark.
If you are still getting the same code, then you need to check the wires going to the TCM. You need to make sure it is getting power and also a good ground. You will have a wire with constant battery voltage and then a second wire will have power when the key is turned on.
If the module is getting a good power and ground, then you need to inspect the bus communication wires for any potential damage or corrosion.
The wire pins will be numbered 1-20 in 3 rows.
The constant battery power is pin 56 and this is red wire with a light blue tracer.
#8 and #11 need power with the key on........one yellow and one red/white.
"Aisin" is a brand name and there is only one transmission control module on your vehicle.
Yes, we'll need to trace the circuit back, so let's wait and see what the results are.
Just reply back when you've had a chance to test the wires.
Ok, check fuse #1 in the inside fuse box. This is a 10 amp fuse.
Looking at the diagrams again, the yellow wire may only get power when the key is in the start position, so re-check that and fuse 1.
