Checking wiring and terminals (automatic transmissions)
- Ignition off.
Check the brake control module and transmission control module (TCM) connectors. Check for damaged or bent terminal pins. Check for contact resistance and oxidation.
Check the wiring for CAN communication between brake control module terminal #11 (#A11) and terminal #2 (#B12) on the transmission control module (TCM) and between brake control module terminal #15 (#A15) and terminal #14 (#B24) on the transmission control module (TCM). Check for an open-circuit. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
Remedy as necessary.
