Troubleshooting Hints

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check the Multi-function Alarm In-line Fuse by visual inspection.
2. If the Seat Belts remain taut with either front door open, check for a shorted Door Latch Switch.
3. If one belt remains taut with either Door Latch Switch operated, check CKT 394, CKT 395 and CKT 150 to the suspected belt solenoid for an open.
^ 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
