DTC CONFIRMATION PROCEDURE
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. Shift the selector lever to N position and wait for 10 seconds or more.
3. Press the P position switch to shift to P position and wait for 10 seconds or more.
4. Check DTC.
Is “P1897” detected?
YES
>> Go to
NO-1 >> To check malfunction symptom before repair: Refer to
GI-53, "Intermittent Incident"
.
NO-2 >> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000010119596
1.
CHECK ENCODER POWER SUPPLY CIRCUIT
1. Power switch OFF.
2. Disconnect the parking actuator connector.
3. Check the voltage between parking actuator vehicle side harness connector terminal and ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
CHECK HARNESS BETWEEN VCM AND ENCODER
1. Power switch OFF.
2. Disconnect the VCM connector.
3. Check the continuity between VCM vehicle side harness connector terminals and parking actuator vehicle
side harness connector terminals.

CHECK HARNESS BETWEEN VCM AND ENCODER
1. Power switch OFF.
2. Disconnect the VCM connector.
3. Check the continuity between VCM vehicle side harness connector terminal and parking actuator vehicle
side harness connector terminal.
4. Check the continuity between VCM vehicle side harness connector terminals and ground.
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"
.
