Without CONSULT

1. Turn ignition switch ON.

2. Check the voltage between ECM harness connector terminals.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to

GI-45, "Intermittent Incident"

>> GO TO 2.

CHECK ASCD STEERING SWITCH GROUND CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Disconnect combination switch (spiral cable) harness connector.

4. Check the continuity between combination switch (spiral cable) and ECM harness connector.

5. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 3.

>> Repair or replace error-detected parts.

CHECK ASCD STEERING SWITCH INPUT SIGNAL CIRCUIT

DTC DETECTION LOGIC

NOTE:

• If DTC P1572 is displayed with DTC P0603, P0604, P0605, P0606, P0607, P060A and P060B, first per-

form the trouble diagnosis for DTC P0603, P0604, P0605, P0606, P0607, P060A and P060B. Refer to

EC-115, "DTC Index"

• This self-diagnosis has the one trip detection logic. When malfunction A is detected, DTC is not

stored in ECM memory. And in that case, 1st trip DTC and 1st trip freeze frame data are displayed.

1st trip DTC is erased when ignition switch OFF. And even when malfunction A is detected in two

consecutive trips, DTC is not stored in ECM memory.

DTC CONFIRMATION PROCEDURE

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

NOTE:

Procedure for malfunction B is not described here. It takes extremely long time to complete procedure for mal-

function B. By performing procedure for malfunction A, the incident that causes malfunction B can be

detected.

>> GO TO 2.

PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A

1. Start engine.

2. Press MAIN switch and make sure that CRUISE indicator is displayed in combination meter.

3. Drive the vehicle for at least 5 consecutive seconds as per the following conditions.

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle.

If a road test is expected to be easier, it is unnecessary to lift the vehicle.

4. Check DTC.
Is DTC detected?

YES

>> Proceed to

EC-480, "Diagnosis Procedure"

>> GO TO 3.

DTC No.

(19 MPH), ON signals from the stop lamp
switch and the brake pedal position switch
are sent to the ECM at the same time.

• Harness or connectors

(Stop lamp switch circuit is shorted.)
(Brake pedal position switch circuit is shorted.)

• Stop lamp switch
• Brake pedal position switch
• Incorrect stop lamp switch installation
• Incorrect brake pedal position switch installa-

tion

• ECM
