Intermittent fault
- Ignition off.
Check the transmission control module (TCM) and transmission connectors. Check for contact resistance and oxidation according to Contact resistance and oxidation .
Check the power supply cable between control module terminal #A59 (#A59) and transmission connector terminal #A2. Check for an intermittent short-circuit to supply voltage according to Short-circuit to supply voltage, intermittent faults .
Check the signal cable between control module terminal #A41 (#A41) and transmission connector terminal #A1. Check for an intermittent short-circuit to supply voltage according to Short-circuit to supply voltage, intermittent faults .
Remedy as necessary.
