Checking The Wiring And Component

Check the cable between transmission control module (TCM) terminal #A13 (#A43) and gear selector module (GSM) terminal #3. Check for a short-circuit to supply voltage.

HINT: With the ignition switched on, the voltage with the gear selector in position N should be 0 V. With the gear selector in position R or D it should be U _bat  .
