MAIN LINE BETWEEN A-BAG AND DLC CIRCUIT

Diagnosis Procedure

INFOID:0000000012200519

1.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect the harness connectors E105 and M77.

4. Check the continuity between the harness connector and the data link connector.

Is the inspection result normal?

YES (Present error)>>Check CAN system type decision again.

YES (Past error)>>Error was detected in the main line between the air bag diagnosis sensor unit and the

data link connector.

NO

>> Repair the main line between the air bag diagnosis sensor unit and the data link connector.

Diagnosis Procedure

INFOID:0000000012200521

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 ECM for damage, bend and loose connection (unit side and

connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of ECM.

2. Check the resistance between the ECM harness connector terminals.

For NISMO RS models

-

Except for NISMO RS models

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the ECM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the ECM. Refer to the following.

• For NISMO RS models: 

EC-187, "Diagnosis Procedure"

• Except for NISMO RS models: 

EC-792, "Diagnosis Procedure"

Is the inspection result normal?

YES (Present error)>>Replace the ECM. Refer to the following.

• For NISMO RS models: 

EC-590, "Removal and Installation"

• Except for NISMO RS models: 

EC-1256, "Removal and Installation"

YES (Past error)>>Error was detected in the ECM branch line.

NO

>> Repair the power supply and the ground circuit.
