DTC 22

Circuit Description
- The airbag warning light is located on the combination meter.
- When the airbag system is normal, the airbag warning light lights up for approx. 6 seconds after the ignition switch is turned from LOCK position to ACC or ON position, and then turns off automatically. If there is a malfunction in the airbag system, the airbag warning light lights up to inform the driver of the abnormality.
- When terminals Tc and T1 of the DLC1 are connected, the diagnostic trouble code is displayed by the blinking of the airbag warning light.
- The airbag warning light circuit is equipped with an electrical connection check mechanism which detects when the connector to the center airbag sensor assembly is not properly connected.
- If the connector to the center airbag sensor assembly is not properly connected, the airbag warning light will not light up.
- Diagnostic trouble code 22 is recorded when a malfunction occurs in the airbag warning light system. If an OPEN malfunction occurs in the airbag warning light system, the airbag warning light does not light up, so that until the malfunction is repaired the diagnostic trouble codes (including code 22) cannot be confirmed.









Troubleshooting for this system is different for when the airbag warning light does not light up and for when diagnostic trouble code 22 is output. Confirm the problem symptoms first before selecting the appropriate troubleshooting procedure.
