  1. Ensure driver's seat belt is fastened. Using scan tool, select BODY, BODY COMPUTER and INPUT/OUPUT. Turn ignition on. Read SEAT BELT SW status on scan tool. If scan tool indicates SEAT BELT SW: CLOSED, go to next step. If scan tool does not indicate SEAT BELT SW: CLOSED, replace Body Control Module (BCM).

If resistance is less than 100 ohms, go to next step. If resistance is greater than 100 ohms, replace BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  4. Disconnect junction block connector C1. See Figure. Using DVOM, measure resistance between seat belt switch connector terminal No. 1 (Light Green/Red wire) and ground.
