Test 43A - Left Front Door Ajar Switch Circuit For Open
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
at end of article.
- Using DRB-II, stop courtesy light actuation test. Open left front door. If courtesy lights operate by opening left front door, go to TEST 43B. If courtesy lights do not operate by opening left front door, go to next step.
- Using DRB-II, read left front door ajar switch status. If DRB-II displays LFDOOR AJAR: CLOSED, replace Body Controller Module (BCM). Module is located behind right kick panel. Perform VERIFICATION PROCEDURE VER-1.
- If DRB-II does not display LFDOOR AJAR: CLOSED, disconnect left front door ajar switch connector. Connect jumper wire between chassis ground and left front door ajar switch connector sense circuit (Tan wire). Using DRB-II, read left front door ajar switch status. If DRB-II displays LFDOOR AJAR: CLOSED, replace left front door ajar switch. Perform VERIFICATION PROCEDURE VER-1.NOTE: The BCM must be connected while performing step 4). Failure to do so may lead to incorrect circuit/system diagnosis.
- If DRB-II does not display LFDOOR AJAR: CLOSED, disconnect jumper wire used in step 3). Access BCM connectors. Connect jumper wire between chassis ground and BCM Gray connector terminal No. 6, left front door ajar switch sense circuit (Tan wire). Using DRB-II, read left front door ajar switch status. If DRB-II displays LFDOOR AJAR: CLOSED, repair open circuit in Tan wire between left front door ajar switch and BCM. Perform VERIFICATION PROCEDURE VER-1. If DRB-II does not display LFDOOR AJAR: CLOSED, replace BCM. Perform VERIFICATION PROCEDURE VER-1.
