NOTE:
Use following procedure if codes are not displayed or air bag warning light stays on when jumper wire is connected between terminals Tc and E1 of DLC.
- Turn ignition switch from LOCK to ACC or ON position. If air bag warning light does not come on, repair air bag warning light circuit. If air bag warning light comes on, measure voltage between terminals Tc and E1 of DLC. See Figure. If battery voltage is present, go to step 3).
- If battery voltage is not present, measure voltage between body ground and terminal Tc of DLC. If battery voltage is present, repair harness between body ground and terminal E1 of DLC. If battery voltage is not present, go to next step.
- Connect a jumper wire between body ground and terminal Tc of center air bag sensor connector. See Figure. If air bag warning light does not come on, replace center air bag sensor. If air bag warning light comes on, repair wiring harness between center air bag sensor and DLC.
