Troubleshooting Hints - Lumbar Seats

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check I/P Fuse Block PWR STS Circuit Breaker 3 for continuity.
2. Check that grounds G201 and G202 are clean and tight.
3. Before component replacement, check for poor connections at related component and in-line harness connector terminal connections.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
