Diagnosis Procedure

INFOID:0000000001162640

1.

CHECK ASCD BRAKE SWITCH CIRCUIT

1.

Turn ignition switch ON.

2.

Check the voltage between ECM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> GO TO 2.

2.

CHECK ASCD BRAKE SWITCH POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect ASCD brake switch harness connector.

3.

Turn ignition switch ON.

4.

Check the voltage between ASCD brake switch harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING PART

Check the following.
• Harness connectors M69, E7 (LHD models)
