TSB : Test Procedure

Details

Verify Condition Turn ignition on. Check for fault codes. If Code 13 is flashing, go to step 2). If Code 13 is not flashing, check connectors, wiring, splices, and crimps for an intermittent problem. DO NOT proceed with diagnostic test until code is flashing. Failure to do so will result in needless replacement of diagnostic monitor. NOTE: Do not attempt to replace diagnostic monitor with Fault Code 13 present unless specifically instructed to do so. Deactivate System Turn ignition off. Deactivate air bag system. See COMPLETE SYSTEM DEACTIVATION . Check for fault codes. If Code 13 is flashing, go to step 5). If Code 13 is not flashing, go to step 3). Check Air Bags & Clockspring Inspect clockspring wiring in steering wheel, driver-side air bag and passenger-side air bag for damaged, chafed or pinched wires. If any component wires are damaged, replace component that has damaged wires. After repair is completed, go to CODE 51 . If wiring is okay, go to step 4). WARNING: For following step, use a DVOM with less than 10 milli-amp short circuit current on lowest resistance scale possible. Failure to use a DVOM of this type may cause air bag to deploy. Verify Short In Air Bags Ensure shorting bars are correctly installed in both driver-side and passenger-side air bag connectors. Measure resistance between either terminal of air bag connector and metal case of air bag module. Perform measurement on both driver-side air bag and passenger-side air bag. If resistance is infinite (open), replace clockspring. After repair is completed, go to CODE 51 . If resistance is not infinite, replace air bag module. After repair is completed, go to CODE 51 . Install Air Bag Simulator At Base Of Steering Wheel Remove air bag simulator from driver-side air bag connector. Disconnect clockspring from main wiring harness at base of steering column. Connect air bag simulator to main wiring harness in place of clockspring connector. Turn ignition on. Check for fault codes. If Code 13 flashes, go to step 6). If Code 13 does not flash, replace clockspring. After repair is completed, go to CODE 51 . Remove Air Bag Simulator From Base Of Steering Wheel Remove air bag simulator from main wiring harness at base of steering column. Remove air bag simulator from passenger-side air bag. Turn ignition on. Check for fault codes. If Code 13 flashes, go to step 7). If Code 13 does not flash, locate and repair short to ground in wire between circuits 615 (Gray/White wire)and 616 (Pink/Black wire). After repair is completed, go to CODE 51 . Check safing sensor Circuit Disconnect safing sensor (located behind driver-side kick panel). Turn ignition on. Check for fault codes. If Code 13 flashes, locate and repair short to ground in circuit 614 (Gray/Orange wire). If Code 13 does not flash, go to step 8). After repair is completed, go to CODE 51 . Verify Short To Ground In safing sensor Measure resistance between ground and circuit 614 (Gray/Orange wire) of safing sensor connector. If resistance to ground is not open, replace safing sensor. After repair is completed, go to CODE 51 . If resistance to ground is open, locate and repair short to ground in circuit 623 (Purple/White wire) between safing sensor and diagnostic monitor. After repair is completed, go to CODE 51 .
