the next step. When malfunction is eliminated, further repair work is not required.

1.

HARNESS CONNECTOR

Visually inspect all applicable harness connectors for the following:

• Visible damage to connector or terminal

• Loose terminal

• Poor connection

NOTE:

All harness connectors should be inspected from the air bag diagnosis unit to the end component (including

any in-line connectors).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Perform one of the following repairs:

• Visible damage: Replace the harness.

• Loose terminal: Secure the terminal.

• Poor connection: Secure the connection.

2.

2. Turn ignition switch ON.

3. Check for DTC using CONSULT.
Is DTC still current?

YES

>> GO TO 3.

NO

>> Refer to 

GI-53, "Intermittent Incident"

.

3.

WIRING HARNESS

Check the wiring harness for visible damage.

NOTE:

The entire wiring harness should be inspected from the air bag diagnosis sensor unit to the end component

(including any in-line connectors).
Is the inspection result normal?

YES

>> GO TO 4.
