Signal Missing. Intermittent Fault

Signal missing. Intermittent fault

Intermittent fault
Check the transmission control module (TCM) and transmission connectors. Check for contact resistance and oxidation according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the wiring between transmission control module (TCM) terminal #A51 (#A51) and transmission connector terminal #D1. Check the wiring between control module terminal #B9 (#A69) and transmission connector terminal #D2. Check for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

Hint: Check the solenoid SLU by measuring the resistance between terminals #D1 and #D2 on transmission connector D. The resistance should be 5-6 ohms at 20°C.

Remedy as necessary.
