SRS Indicator Circuit Troubleshooting
The SRS Indicator Doesn't Come On
1. Turn the ignition switch ON (ll), and see if the otherindicators come on {brake system, etc).
Do the other indicators come on?
YES Go to step 2.
NO-Go to step 8.
2. Turn the ignition switch OFF, then remove thegauge assembly {see page 22-641. Disconnectgauge assembly connector A and B from the gauge
assembly.
Check resistance between the No. 12 terminal ofgauge assembly connector B (22P) and bodyground. There should be 0 1.0 Q.

Is the resistance as specified?
YES Go to step 4.
NO Open in the BLK wire of dashboard wire
harness A or faulty body ground terminal (G501). lf
the body ground terminal is OK, replace dashboard
wire harness A.Il{,

4. Check for voltage between the No. l4terminal ofgauge assembly connector A (22P) and bodyground within the first 6 seconds after turning the
ignition switch ON (ll). There should be 8.5 V or less.

Is the voltage as specified?
YES-Faulty SRS indicator clrcuit in the gauge
assembly; replace the gauge assembly.I
NO-Go to step 5.

38. Remove the gauge assembly (see page 22-64), then
disconnect gauge assembly connector A from the
gauge assemDly,
Check resistance between the No. 5 terminal of
SRS unit connector C (8P) and body ground. There
should be an ooen circuit, or at least 1 fM Q ,

NO Short to ground in the floor wire harness or in
dashboard wire harness A; replace the faulty
harness.l

40. Remove the gauge assembly (see page 22-64), then
disconnect gauge assembly connector A from the
gauge assembly.
Check resistance between the No. 14 terminal of
gauge assembly connector A (22P) and the No.5
terminal of SRS unit connector C (8P). There should
be 'l 0 or less,

SRS UNIT CONNECTOR C (8P}
ls the resistance as specitied?
YES Faulty SRS indicator circuit in the gauge
assembly or poor contact at gauge assembly
connector A (22P); check the connection. lf the
connection is OK, replace the gauge assembly,I
NO Open in the floor wire harness or in
dashboard wire harness A; replace the faulty
harness. !
