Troubleshooting Hints - Lumbar Seats

- To avoid misdiagnosis, inspect pneumatic lines for pinched, broken or disconnected conditions which would result in system failure.

1. Replace Circuit Breaker A with a known good 30A circuit breaker.
2. Make sure that ground G200 is clean and tight.
3. For repeated Lumbar Relay Module failures, check CKT 769 for short to B+.
4. Check LH and RH Lumbar In-line Fuse. If open, check appropriate CKT 21 for a short to ground.
