Test Procedure
- Verify Condition
Turn ignition on. Check for fault codes. If Code 52 is flashing, go to step 2). If Code 52 is not flashing, check connectors, wiring and crimps for an intermittent problem. DO NOT proceed with diagnostic test unless code is flashing. Doing so will result in needless replacement of system components.
- Deactivate System
Deactivate air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM
. Turn ignition on. Wait 30 seconds. Measure voltage between terminals No. 3 (Black/White wire) and No. 15 (White/Orange wire) at diagnostic monitor Gray connector. See Figure
. If voltage is 16-19 volts, replace diagnostic monitor. If voltage is not 16-19 volts, go to step 3).
- Check For Open Circuit
Turn ignition off. Disconnect diagnostic monitor. Check for continuity between terminals No. 3 (Black/White wire) and No. 15 (White/Orange wire) at diagnostic monitor Gray connector. See Figure
. If continuity exists, go to step 4). If continuity does not exist, replace diagnostic monitor.
- Check Circuit No. 611
Disconnect safing sensor. Safing sensor is located behind right side kick panel. Check for continuity between terminal No. 3 (Black/White wire) and No. 15 (White/Orange wire) of diagnostic monitor Gray connector. See Figure
. If continuity does not exist, go to step 5). If continuity exists, locate and repair short to ground in circuit No. 611 (White/Orange wire).
- Check For Short In Sensor
Check for continuity between ground and White/Orange wire in safing sensor connector. If continuity does not exist, locate and repair short to ground in circuit No. 612 (Purple/Orange wire). If continuity exists, replace safing sensor.
