3. Check the terminals and connectors of the ICC sensor 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 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 - Repair the ICC sensor branch line.
3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the ICC sensor. Electrical Diagrams.
Is the inspection result normal?
YES (Present error)-Replace the ICC sensor. ICC Sensor Integrated Unit.
YES (Past error)-Error was detected in the ICC sensor branch line.
