DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.

1.

PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, power switch OFF and wait for at least

10 seconds, then perform the next test.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Set the vehicle to READY.

2. Accelerate the vehicle up to 50 km/h (31 MPH) and then depress the brake pedal to decelerate and stop

the vehicle.

3. Repeat step 2 five more times.

4. Check DTC.
Is “P0571” detected? 

YES

>> Go to 

TM-66, "Diagnosis Procedure"

.

NO-1 >> To check malfunction symptom before repair: Refer to 

GI-53, "Intermittent Incident"

.

NO-2 >> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010119574

1.

CHECK STOP LAMP SWITCH SIGNAL

With CONSULT

1. Set the vehicle to READY.

2. Select “Data Monitor” in “SHIFT”.

3. Select “BRAKE SWITCH” and “BRAKE SWITCH (CAN)”.

4. Identify an abnormal signal value.

Which signal value is abnormal?

BRAKE SWITCH>>GO TO 2.

BRAKE SWITCH (CAN)>>GO TO 5.

2.

CHECK STOP LAMP SWITCH POWER SUPPLY CIRCUIT

1. Power switch OFF.

2. Disconnect the stop lamp switch connector.

3. Check the voltage between stop lamp switch vehicle side harness connector terminal and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

DETECTION OF MALFUNCTION ITEMS

Check the following items:

• Harness open circuit or short circuit between the stop lamp switch vehicle side harness connector and 12V

battery.

• 12V battery

• 20A fuse (#77) (Refer to 

PG-87, "How To Check"

.)

Is the inspection result normal?

>> Repair or replace the malfunctioning parts.

4.

CHECK STOP LAMP SWITCH SIGNAL INPUT CIRCUIT

1. Disconnect the VCM connector.

2. Check the continuity between VCM vehicle side harness connector terminal and stop lamp switch vehicle

side harness connector terminal.

3. Check the continuity between VCM vehicle side harness connector terminal and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace the malfunctioning parts.

5.

CHECK STOP LAMP SWITCH

Check the stop lamp switch. Refer to 

BRC-100, "Component Inspection"

.

Is the inspection result normal?

YES

>> Replace the VCM due to malfunction in the electric shift control module built in VCM. Refer to

EVC-423, "Removal and Installation"

.

NO

>> Replace the stop lamp switch. Refer to
