SRS Symptom Troubleshooting - SRS indicator stays on, but no DTCs are stored, or cannot be read
SRS indicator stays on, but no DTCs are stored, or cannot be read
NOTE:
- 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 Service and Repair.
- 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, then wait at least 3 minutes.
2. Disconnect SRS unit connector A (28P) from the SRS unit.
3. Remove the gauge control module Service and Repair.
4. Disconnect the gauge control module 36P connector (A) from the gauge control module.
5. Measure the resistance between gauge control module 36P connector terminal No. 12 and SRS unit connector A (28P) terminal No. 11. There should be less than 1.0 Ohms.
Is the resistance as specified?
YES -
Go to step 6.
NO -
Open in the dashboard wire harness A or the dashboard wire harness B; replace the faulty harness.�
6. Reconnect the gauge control module 36P connector to the gauge control module.
7. Reconnect the negative cable to the battery.
8. Install a jumper wire between gauge control module 36P connector terminals No. 2 and No. 12.
9. Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes 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 SRS Unit Replacement. If the DTC does not clear, replace the harness.�
NO -
Faulty SRS indicator circuit in the gauge control module or poor connection at the gauge control module 36P connector; check the connection. If the connection is OK, replace the gauge control module Service and Repair.�
