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 driver airbag connector, and connect the new driver airbag to connector I-055.

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 driver airbag connector I-055 and SRS control module assembly connector I-046/B-072.
c. Disconnect the spiral cable connector I-054 and instrument panel wire harness connector I-012.
d. Disconnect the instrument panel wire harness connector I-036 and body wire harness connector B-055

(*2) .

e. Check if wire harnesses are worn, pierced, pinched or partially broken.
f. Check for broken, bent, protruded or corroded terminals.
g. Check if related connector terminal contact pins are in good condition.

a. Turn ignition switch to LOCK, disconnect the negative

battery cable and wait for at least 90 seconds.

b. Disconnect the SRS control module assembly connector

I-046/B-072.

c. Disconnect the driver airbag connector I-055.
d. Connect the negative battery cable and wait for a few

seconds.

e. Turn ignition switch ON.
f. Using a digital multimeter, measure the voltage between

driver airbag connector I-055 and body ground to check
for a short circuit to power supply according to the table
below.
