Component Tests and General Diagnostics

1. If Power Door Locks operate, PWR Seat Circuit Breaker is OK.
2. Check ground G400 by noting operation of LH Tail/Stop/Turn Lamps.
3. Check motor linkage for poor connection or binding.
4. If the PWR ACCY Circuit Breaker opens whenever the Power Seat Switch is operated, check for a short to ground through CKTs 282, 283, 284, 285, 286 or 287.
^ 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 (refer to General Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis.
