DTC 25/35: Security Indicator Status: Testing
CAUTION:
Do not use test light or battery voltage to test SECURITY indicator LED or LED will be damaged. Test light is okay to test LED circuits with LED disconnected.
NOTE:
Perform diagnostic test when DTC 25/35 is not set or if SECURITY indicator is inoperative.
NOTE:
SECURITY indicator is a Light Emitting Diode (LED).
- Disconnect SECURITY indicator 2-pin connector. Connect test light between SECURITY indicator 2-pin connector terminal "A" (Black wire) and battery voltage. If test light comes on, go to next step. If test light does not come on, go to step 3 .
- Using a DVOM in diode scale, connect DVOM positive (Red) test lead to SECURITY indicator terminal "B" (Dark Green wire). Connect negative (Black) test lead to SECURITY indicator terminal "A" (Black wire). If SECURITY indicator comes on, go to step 4 . If SECURITY indicator does not come on, go to step 5 .
- Repair open Black wire between SECURITY indicator 2-pin connector and ground.
- Check for faulty connection between BCM and SECURITY indicator circuit. Repair circuit as necessary. If circuit is okay, go to step 6 .
- Replace SECURITY indicator. Disconnect and reconnect negative battery cable. Recheck system operation.
