All SRS wiring harnesses are covered with yellow out-
Before disconnecting any part of the SRS wire hap
ness, install the short connectors (see page 24-10(’93-’96))
Replace the entire affected SRS harness assembly if
it has an open circuit or damaged wiring.
After installing the gauge assembly, recheck the oper-
ation of the SRS indicator light.
Remove the dashboard lower cover, center panel and
instrument panel. Disconnect the connector “B”
OOP) from the gauge assembly (see page 23-127).
Inspect the connector terminals to be sure they are
all making good contact.
If the terminals are bent, loose, or corroded, repair
them as necessary, and recheck the system.
If the terminals look OK, make the following input tests
at the connector.
— If a test indicates a problem, find and correct the
cause, then recheck the system.
