SRS Indicator Stays On, But No DTCs Are Stored
SRS indicator stays on, but no DTCs are storedNOTE:
- A new SRS unit must sense the entire system is OK before completing its initial self-test. The most common cause of an incomplete self-test is the failure to replace all deployed parts after a collision, in particular seat belt tensioners, or seat belt buckle tensioners.
- A battery/system voltage above 15.2 V can cause the SRS indicator to come on without storing any DTCs.
1. Disconnect the battery negative cable, and wait for 3 minutes.
2. Disconnect SRS unit connector B (8P) from the SRS unit.
3. Remove the gauge assembly. Disconnect gauge assembly connector A (22P) from the gauge assembly
4. Check resistance between the No. 15 terminal of gauge assembly connector A (22P) and the No. 5 terminal of SRS unit connector C (8P). There should be 1 Ohm or less.
Is the resistance as specified?
YES - Go to step 5.
NO - Open in the floor wire harness or dashboard wire harness; replace the faulty wire harness.
5. Reconnect the battery negative cable.
6. Reconnect gauge assembly connector A (22P) to the gauge assembly.
7. Turn the ignition switch ON (II).
8. Install a jumper wire between the No. 15 terminal of the gauge assembly connector A (22P) and the No. 7 terminal of the gauge assembly connector B (18P). The SRS indicator should go off.
Does the SRS indicator go off?
YES - Faulty SRS unit or poor contact at SRS unit connector C (8P) and the SRS unit; check the connection. If the connection is OK, replace the SRS unit.
NO - Faulty SRS indicator circuit in the gauge assembly or poor contact at gauge assembly connector A or B; check the connection. If the connection is OK, replace the gauge assembly.
