Test 74B - Left Front Door Ajar With Visual Message Center
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
at end of article.
- Disconnect left front door ajar switch connector. Connector is located at lower left "B" pillar. Using DRB-II, read door ajar switch status. If DRB-II does not display CIRCUIT CLOSED, replace left front door ajar switch. Perform VERIFICATION PROCEDURE VER-1.
- If DRB-II displays CIRCUIT CLOSED, disconnect visual message center 11-pin connector. Check condition of connector, and clean or repair connector as necessary. Inspect visual message center circuit board. Repair or replace circuit board as necessary. Perform VERIFICATION PROCEDURE VER-1.
- If circuit board is okay, ensure DRB-II is still reading door ajar switch status. If DRB-II does not display CIRCUIT CLOSED, repair short to ground in Tan/White wire. Perform VERIFICATION PROCEDURE VER-1. If DRB-II displays CIRCUIT CLOSED, disconnect Body Control Module (BCM) connectors. BCM is located behind right side kick panel.
- Check condition of connectors, and clean or repair connectors as necessary. Turn ignition off. Using DRB-II in ohmmeter mode, check resistance on terminal No. 1 (Tan/White wire) of BCM Black or Red connector. If resistance is more than 5 ohms, replace BCM. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is less than 5 ohms, disconnect vehicle theft alarm (if equipped). See Figure . Check resistance on terminal No. 1 (Tan/White wire) of BCM Black or Red connector. If resistance is less than 5 ohms, repair short to ground in Tan/White wire. Perform VERIFICATION PROCEDURE VER-1. If resistance is more than 5 ohms, replace vehicle theft alarm module. Perform VERIFICATION PROCEDURE VER-1.
