SRS indicator does not come on
- Turn the ignition switch ON (II), and see if the other indicators come on (brake system, etc.).
Do the other indicators come on?
YES -Go to step 2.
NO -Go to step 9.
- Turn the ignition switch OFF, then remove the gauge control module (see GAUGE CONTROL MODULE REPLACEMENT ). Disconnect gauge control module connectors A and B from the gauge control module.
- Measure the resistance between the No. 18 terminal of gauge control module connector B (18P) and body ground. There should be 0-1.0 Ω.Fig 2: Measuring Resistance Between No. 18 Terminal Of Gauge Control Module Connector B (18P) And Body Ground

Is the resistance as specified?
YES -Go to step 4.
NO -Open in the dashboard wire harness or junction connector, or faulty body ground terminal (G503) (see DASHBOARD WIRE HARNESS (RIGHT BRANCH) ). If the body ground terminal is OK, replace the dashboard wire harness.
- Measure the voltage between the No. 7 terminal of gauge control module connector B (18P) and body ground within the first 6 seconds after turning the ignition switch ON (II). There should be about 1.0 V for 6 seconds and then about 11 V.Fig 3: Measuring Voltage Between No. 7 Terminal Of Gauge Control Module Connector B (18P) And Body Ground

Is the voltage as specified?
YES -Faulty SRS indicator circuit in the gauge control module; replace the gauge control module.
NO -Go to step 5.
- Turn the ignition switch OFF. Disconnect the negative cable from the battery, then wait for 3 minutes.
- Disconnect SRS unit connector A (28P) from the SRS unit (see DISCONNECTING SYSTEM CONNECTORS ).
- Reconnect the negative cable to the battery.
- Connect a voltmeter between the No. 7 terminal of gauge control module connector B (18P) and body ground. Turn the ignition switch ON (II), and measure the voltage. There should be 0.5 V or less.Fig 4: Connecting Voltmeter Between No. 7 Terminal Of Gauge Control Module Connector B (18P) And Body Ground

Is the voltage as specified?
YES -Faulty SRS unit; replace the SRS unit (see SRS UNIT REPLACEMENT ).
NO -Short to power in the dashboard wire harness or junction connector; replace the dashboard wire harness.
- Turn the ignition switch OFF. Check the No. 21 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse blown?
YES -Go to step 11.
NO -Go to step 10.
- Connect a voltmeter between the No. 10 terminal of the gauge control module connector B (18P) and body ground. Turn the ignition switch ON (II), and measure the voltage. There should be battery voltage.Fig 5: Connecting Voltmeter Between No. 10 Terminal Of Gauge Control Module Connector B (18P) And Body Ground

Is there battery voltage?
YES -Faulty SRS indicator circuit in the gauge control module or poor contact at gauge control module connector B (18P) and the gauge control module; if the connection is OK, replace the gauge control module.
NO -Open in the under-dash fuse/relay box No. 21 (7.5 A) fuse circuit, or open in the YEL wire of the dashboard wire harness or junction connector. If the under-dash fuse/relay box is OK, replace the dashboard wire harness.
- Replace the No. 21 (7.5 A) fuse, then check to see if the indicators comes on.
Do the indicators come on?
YES -The system is OK at this time.
NO -Repair the short to ground in the under-dash fuse/relay box No. 21 (7.5 A) fuse circuit.
