Incorrect Ambient Temperature Reading

NOTE: Perform OTIS TEST 1A  before proceeding with this test. For connector terminal identification and wiring diagrams, see BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST: VER-2A  after each repair. Drive vehicle at least 3 miles (greater than 25 MPH) to update OTIS and perform VERIFICATION TEST: VER-2A  after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting any module connector.
  1. Disconnect Body Control Module (BCM) Bone 12-pin connector C3. BCM is mounted to junction block located behind left end cap of instrument panel. See Figure.
  2. Measure resistance between ground and terminal No. 5 (Violet/Dark Green wire) on Bone connector. If resistance is less than 50 k/ohms, repair Violet/Dark Green wire for partial short to ground. If resistance is 50 k/ohms or greater, go to next step.
  3. Measure resistance between terminals No. 5 and 10 on Bone connector. If resistance is less than 50 k/ohms, repair Violet/Dark Green wire for partial short to Dark Blue/Gray wire. If resistance is 50 k/ohms or greater, replace BCM.
