Seat Adjuster Switch Circuit Test
- Ignition OFF, disconnect the harness connector at the S64D Seat Adjuster Switch - Driver.
- Test for less than 10 Ω between the ground circuit terminal B and ground.
- Ignition OFF.
- Test for less than 2 Ω in the ground circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, repair the open/high resistance in the ground connection.
- Ignition ON.
- Verify a test lamp illuminates between the B+ circuit terminal D and ground.
- If the test lamp does not illuminate
- Ignition OFF
- Test for infinite resistance between the B+ circuit and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- Test for less than 2 Ω in the B+ circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, verify the circuit breaker is not open and there is voltage at the circuit breaker.
- If the test lamp illuminates
- Test or replace the S64D Seat Adjuster Switch - Driver.
