Intermittent Fault

Intermittent fault






Check outside temperature sensor and control module connectors for contact resistance and oxidation according to Checking wiring and terminals - Intermittent faults. Checking Wiring and Terminals

Check cable between ECC control module #A19 and outside temperature sensor terminal 2 for an intermittent open-circuit according to Checking wiring and terminals - Intermittent faults and an intermittent short-circuit to supply voltage according to Checking wiring and terminals - Intermittent faults. Checking Wiring and Terminals

Check cable between control module #A22 and outside temperature sensor terminal 4 for an open-circuit according to Checking wiring and terminals - Intermittent faults and an intermittent short-circuit to supply voltage according to Checking wiring and terminals - Intermittent faults. Checking Wiring and Terminals

Remedy as necessary.
