SRS indicator stays on, but no DTCs are stored

SRS indicator stays on, but no DTCs are stored ('06-07 Models)

NOTE:
- If you cannot retrieve DTCs with the HDS using the SRS menu method, retrieve flash codes with the HDS in SCS mode.
- 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 negative cable from the battery, and wait for 3 minutes.




2. Disconnect SRS unit connector A (28P) from the SRS unit.




3. Remove the gauge assembly. Disconnect gauge assembly connector B (30P) from the gauge assembly.




4. Check resistance between the No. 19 terminal of gauge assembly connector B (30P) and the No. 11 terminal of SRS unit connector A (28P). There should be 1 ohm or less.

Is the resistance as specified?

YES - Go to step 5.

NO - Open in the dashboard wire harness A or SRS main harness; replace the faulty harness.

5. Reconnect the negative cable to the battery.
6. Reconnect gauge assembly connector B (30P) to the gauge assembly.
7. Turn the ignition switch ON (II).




8. Install a jumper wire between the No. 9 terminal of the gauge assembly connector A (22P) and the No. 19 terminal of the gauge assembly connector B (30P). The SRS indicator should go off.

Does the SRS indicator go off?

YES - Faulty SRS unit or poor connection at SRS unit 28P connector 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 connection at gauge assembly connector A or B; check the connection. If the connection is OK, replace the gauge assembly.
