Test 84B - Incorrect Ambient Temperature Reading
NOTE:
Perform TEST 84A
before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION
and WIRING DIAGRAMS
. Drive vehicle to update OTIS and perform TEST VER-1 - VERIFICATION PROCEDURE
after each repair.
- Disconnect Body Control Module (BCM) Bone and Gray connectors. BCM is located behind right kick panel. Using scan tester in ohmmeter mode, measure resistance at terminal No. 15 (Gray/Tan wire) on BCM Bone connector. If resistance is less than 500 k/ohms, repair Gray/Tan wire for partial short to ground. If resistance is 500 k/ohms or greater, go to next step.
- Using scan tester in ohmmeter mode, measure resistance at terminal No. 10 (Violet/Light Green wire) on BCM Gray connector. If resistance is less than 500 k/ohms, repair Violet/Light Green wire for partial short to ground. If resistance is 500 k/ohms or greater, go to next step.
- Using external ohmmeter, measure resistance between terminal No. 15 (Gray/Tan wire) on BCM Bone connector and terminal No. 10 (Violet/Light Green wire) on BCM Gray connector. If resistance is less than 500 k/ohms, repair Violet/Light Green wire for short to Gray/Tan wire. If resistance is 500 k/ohms or greater, replace BCM.
