SRS Indicator Stays On When In "SCS" Menu Method
SRS Indicator Circuit TroubleshootingThe SRS Indicator Stays On When In "SCS" Menu Method
1. Check for blown No. 2 (10 A) fuse in the driver's under-dash fuse/relay box.
Is the fuse OK?
YES - Go to step 2.
NO - Replace the No. 2 (10 A) fuse. Turn the ignition switch ON (II), and check for blown No. 2 (10 A) fuse. If the fuse is blown, replace the SRS main harness. If the fuse is OK; replace the SRS unit.
2. Disconnect the driver's airbag 2P connector (A) and front passenger's airbag 4P connector (B).
3. Disconnect the SRS main harness 18P connector (A) from the SRS unit (B).
4. Connect a voltmeter between the No. 4 terminal (+) of the SRS main harness 18P connector and body ground.
5. Turn the ignition switch ON (II).
Is there battery voltage?
YES - Go to step 6.
NO - Open in the SRS main harness (VB line); replace the SRS main harness.
6. Turn the ignition switch OFF. Disconnect the SRS main harness 8P connector (A) from the SRS unit (B).
7. Connect the No, 4 terminal of the SRS main harness 18P connector and the No. 5 terminal of the SRS main harness 8P connector with a jumper wire and backprobe adapters. Turn the ignition switch ON (II).
Does the SRS indicator go off?
YES - Faulty SRS unit or poor contact at the SRS main harness 18P connector or poor contact at the SRS main harness 8P connector; check the connectors. If the connectors are OK, replace the SRS unit .
NO - Go to step 8.
8. Turn the ignition switch OFF. Check the No. 2 (10 A) fuse in the driver's under-dash fuse/relay box.
Did fuse No. 2 (10 A) blow?
YES - Go to step 9.
NO - Go to step 11.
9. Disconnect the dashboard wire harness A 18P connector (A) from the gauge assembly.
10. Check resistance between the No. 5 terminal of the SRS main harness 8P connector and body ground. There should be 1 MOhm, or more.
Is the resistance as specified?
YES - Short to ground in the gauge assembly; replace the gauge assembly.
NO - Short to ground in the BLU wire of the dashboard wire harness A or the SRS main harness; replace the dashboard wire harness or the SRS main harness.
11. Disconnect the dashboard wire harness 18P connector (A) from the gauge assembly.
12. Check resistance between the No. 5 terminal of the SRS main harness 8P connector and the No. 17 terminal of the dashboard wire harness A 18P connector. There should be 0 - 1.0 Ohm.
Is the resistance as specified?
YES - Faulty SRS indicator circuit in the gauge assembly; replace the SRS indicator circuit board in the gauge assembly.
NO - Open in the BLU wire of dashboard wire harness A or the SRS main harness; replace dashboard wire harness A or the SRS main harness.
