APA 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).
-Accelerator pedal actuator
-Harness connector M151
-Harness connector M150
-Harness connector M23 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 accelerator pedal actuator.
2.Check the resistance between the accelerator pedal actuator 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 accelerator pedal actuator. Accelerator Pedal Actuator.
Is the inspection result normal?
YES (Present error)-Replace the accelerator pedal assembly. With Distance Control Assist System.
YES (Past error)-Error was detected in the accelerator pedal actuator branch line.
NO- Repair the power supply and the ground circuit.

4. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.Disconnect the harness connector M23.
2.Check the continuity between the accelerator pedal actuator harness connector and the harness connector.





Is the inspection result normal?
YES- Replace the PCB harness.
NO- Repair the harness between the accelerator pedal actuator harness connector M152 and the harness connector M23.
