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.
- 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 A (28P) from the SRS unit.
3. Remove the gauge control module. Disconnect the gauge control module (36P) connector (A) from the gauge control module.
4. Check resistance between the No. 12 terminal of gauge control module connector (36P) and the No. 11 terminal of SRS unit connector A (28P). There should be 0-1 ohm.
Is the resistance as specified?
YES - Go to step 5.
NO - Open in the dashboard wire harness or dashboard wire harness B; replace the faulty harness.
5. Reconnect the battery negative cable.
6. Reconnect the gauge control module connector (40P) to the gauge control module.
7. Turn the ignition switch ON (II).
8. Install a jumper wire between the No. 2 terminal and the No. 12 terminal of the gauge control module connector (36P). The SRS indicator should go off.
Does the SRS indicator go off?
YES - Faulty SRS unit or poor connection at SRS unit connector A (28P) and the SRS unit; check the connection. If the connection is OK, replace the SRS unit.
NO - Faulty SRS indicator circuit in the gauge control module or poor connection at the gauge control module connector (36P); check the connection. If the connection is OK, replace the gauge control module.
