Checking the wiring
- Ignition off.
- Breakout box connected.
Check the communication cable between transmission control module (TCM) #B1 (#B11) and engine control module (ECM) #B1 (#B11) for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
Check the communication cable between transmission control module (TCM) #B13 (#B23) and engine control module (ECM) #B13 (#B23) for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
Check the communication cables between transmission control module (TCM) #B2 (#B12), junction point 53/352, connector 54/3R #B1 and the central electronic module (CEM) #B18 for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
Check the communication cables between transmission control module (TCM) #B14 (#B24), junction point 53/353, connector 54/3R #B2 and the central electronic module (CEM) #B17 for an open-circuit according to Open-circuit, permanent faults , a short-circuit to ground according to Short-circuit to ground, permanent faults and a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .
