LASER BRANCH LINE CIRCUIT

Diagnosis Procedure


1. CHECK CONNECTOR

1.Turn the ignition switch OFF.
2.Disconnect the battery cable from the negative terminal.
3.Check the following terminals and connectors for damage, bend and loose connection (unit side and connector side).
-ICC sensor
-Harness connector E106
-Harness connector M6
-Harness connector M28 and PCB harness side connector
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 ICC sensor.
2.Check the resistance between the ICC sensor harness connector terminals.





Is the measurement value within the specification?
YES- GO TO 3.
NO- GO TO 4.

3. CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the ICC sensor. ICC Sensor.
Is the inspection result normal?
YES (Present error)-Replace the ICC sensor. Removal And Installation.
YES (Past error)-Error was detected in the ICC sensor branch line.
NO- Repair the power supply and the ground circuit.

4. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.Disconnect the harness connector M28.
2.Check the continuity between the ICC sensor harness connector and the harness connector.





Is the inspection result normal?
YES- Replace the PCB harness.
NO- Repair the harness between the ICC sensor harness connector E67 and the harness connector
M28.
