Self-diagnosis Detection Logic
HINT:
When performing electrical diagnosis and test, always refer to the relevant circuit diagram for the special
circuit and component information.
Diagnosis Procedure
a. Turn ignition switch to LOCK, disconnect the negative battery cable and wait for at least 90 seconds.
b. Disconnect front passenger seat belt switch connector, and connect the new front passenger seat belt
switch connector to connector B-050.
c. Reconnect the negative battery cable and wait for a few seconds.
d. Turn ignition switch ON and wait for at least 90 seconds.
e. Use X-431 3G diagnostic tester to clear the DTCs.
f. Turn ignition switch to LOCK.
g. Turn ignition switch ON and wait for at least 90 seconds.
h. Use X-431 3G diagnostic tester to check if the DTCs are still output.
Use circuit diagram as a guide to perform the following procedures:
a. Turn ignition switch to LOCK, disconnect the negative battery cable and wait for at least 90 seconds.
b. Disconnect the front passenger seat belt switch connector B-050 and SRS control module assembly
connector I-046/B-072.
c. Disconnect the body wire harness connector B-003 and instrument panel wire harness connector I-006
(*1).
d. Check if wire harnesses are worn, pierced, pinched or partially broken.
e. Check for broken, bent, protruded or corroded terminals.
f. Check if related connector terminal contact pins are in good condition.
