- Ignition OFF, disconnect the X4 harness connector at the K40D Seat Memory Control Module - Driver, ignition ON.
- Verify a test lamp illuminates between the B+ circuit terminal 5 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.
- Go to next step: If infinite resistance
- 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 fuse is not open and there is voltage at the fuse.
- Go to next step: If the test lamp illuminates
- Ignition OFF, connect the X4 harness connector at the K40D Seat Memory Control Module - Driver and disconnect the X3 harness connector at the K40D Seat Memory Control Module - Driver.
