SRS Indicator Does Not Come On
SRS Indicator Light Doesn't Come On1. Turn the ignition switch ON (II), and check to see if the other indicator lights come on (brake system, etc).
Do the other indicator lights come on?
YES - Go to step 5.
NO - Go to step 2.
2. Turn the ignition switch OFF, and check the No.9 (7.5 A) fuse in the driver's under-dash fuse/relay box.
Is the fuse OK?
YES - Go to step 14.
NO - Go to step 3.
3. Replace the No.9 (7.5 A) fuse, and check to see if the SRS indicator light comes on.
Does the SRS indicator light come on?
YES - The system is OK.
NO - Go to step 4.
4. Check for an open in the wire harness between fuse No.9 (7.5 A) and the gauge assembly, and repair. Check that the SRS indicator light comes on.
Does the SRS indicator light come on?
YES - The system is OK.
NO - Short to ground in the gauge assembly; replace the circuit board in the gauge assembly.
5. Turn the ignition switch OFF.
6. Remove the gauge assembly.
7. Check for blown SRS indicator light bulb.
Is the SRS indicator light bulb OK?
YES - Go to step 8.
NO - Blown SRS indicator bulb; replace the bulb.
8. Disconnect gauge assembly connector C (16P) from the gauge assembly.
9. Connect a volt meter between the No. 9 terminal of gauge assemble connector C (16P) and body ground.
10. Turn the ignition switch ON (II), and measure voltage.
Is there 8.5 V or less for six seconds after the ignition switch has been turned ON (II)?
YES - Faulty SRS indicator light circuit in the gauge assembly; replace the SRS indicator circuit board in the gauge assembly.
NO - Go to step 11.
11. Turn the ignition switch OFF.
12. Disconnect SRS unit connector C (8P) from the SRS unit.
13. Connect a voltmeter between the No. 5 terminal of SRS unit connector C (8P) and body ground. Turn the ignition switch ON (II), and measure voltage. There should be 0.5V or less.
Is voltage as specified?
YES - Faulty SRS unit; replace the SRS unit.
NO - Short to power in the BLU wire of the dashboard wire harness A; replace dashboard wire harness A or the SRS main harness.
14. Disconnect gauge assembly connector B (22P) from the gauge assembly.
15. Connect a voltmeter between the No. 11 terminal of gauge assembly connector B (22P) and body ground. Turn the ignition switch ON (II), and measure voltage. The should be battery voltage.
Is voltage as specified?
YES - Go to step 16.
NO - Open in dashboard wire harness A; repair or replace dashboard wire harness A.
16. Turn the ignition switch OFF. Check resistance between the No. 16 terminal of gauge assembly connector B (22P) and body ground. There should be 0-1.0 Ohm.
Is the resistance as specified?
YES - Faulty SRS indicator light circuit in the gauge assembly; replace the SRS indicator circuit board in the gauge assembly.
NO - Open in dashboard wire harness A or bad body ground; check the body ground connection. If it is OK, repair or replace dashboard wire harness A.
