A-BAG BRANCH LINE CIRCUIT

Diagnosis Procedure

INFOID:0000000005595413

WARNING:

• Before servicing, turn ignition switch OFF, disconnect battery negative terminal, and wait 3 minutes

or more. (To discharge backup capacitor.)

• Never use unspecified tester or other measuring device.

1.

CHECK CONNECTOR

Check the terminals and connectors of the air bag diagnosis sensor unit for damage, bend and loose connec-
tion (unit side and connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace the terminal and connector.

2.

CHECK AIR BAG DIAGNOSIS SENSOR UNIT

Check the air bag diagnosis sensor unit. Refer to the following.
• For USA and CANADA: 

SRC-8, "Work Flow"

• For  MEXICO: 

SRC-180, "Work Flow"

Is the inspection result normal?

YES

>> Replace the main harness.

NO

>> Replace parts whose air bag system has a malfunction.

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the terminals and connectors of the BCM for damage, bend and loose connection (unit side and
connector side).

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1.

Disconnect the connector of BCM.

2.

Check the resistance between the BCM harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the BCM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the BCM. Refer to 

BCS-42, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the BCM. Refer to 

BCS-95, "Removal and Installation"

.

YES (Past error)>>Error was detected in the BCM branch line.
NO
