P1816 TRANSMISSION RANGE SWITCH

Description

INFOID:0000000005275438

The transmission range switch transmits the A/T position indicator signal (transmission range switch signal)
via CAN communication to the transfer control unit.  DTC P1816 will set when the transmission range switch
signal is malfunctioning or there is a communication error.

Diagnosis Procedure

INFOID:0000000005275440

1.

CHECK DTC WITH TCM

Perform self-diagnosis with TCM. Refer to 

DLN-17, "CONSULT-III Function (ALL MODE AWD/4WD)"

.

Is any malfunction detected by self-diagnosis?

YES

>> Check the malfunctioning system.

NO

>> GO TO 2.

2.

CHECK TRANSFER CONTROL UNIT

Check transfer control unit input/output signal. Refer to 

DLN-55, "Reference Value"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check transfer control unit pin terminals for damage or loose connection with harness connector.

If any items are damaged, repair or replace damaged parts.

3.

CHECK DTC

Drive the vehicle and then perform self-diagnosis.

Is DTC P1816 displayed?

YES

>> Perform self-diagnosis with TCM again.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000005275443

Regarding Wiring Diagram information, refer to 

DLN-60, "Wiring Diagram"

.

1.

CHECK PARK/NEUTRAL POSITION SWITCH SIGNAL

1.

Turn ignition switch ON.

2.

Check voltage between transfer control unit harness connector
M152 terminal 33 and ground.

Is the inspection result normal?

YES 

>> GO TO 5.

NO

>> GO TO 2.

2.

CHECK HARNESS BETWEEN TRANSFER CONTROL UNIT AND PARK/NEUTRAL POSITION SWITCH

1.

Turn ignition switch OFF.  (Stay for at least 5 seconds.)

2.

Disconnect transfer control unit harness connector and the park/neutral position switch harness connec-
tor.

3.

Check continuity between transfer control unit harness connec-
tor M152 terminal 33 and park/neutral position switch harness
connector F66 terminal 1.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace damaged parts.

3.

CHECK GROUND CIRCUIT

1.

Turn ignition switch OFF.  (Stay for at least 5 seconds.)

2.

Disconnect park/neutral position switch harness connector.

3.

Check continuity between park/neutral position switch harness
connector F66 terminal 2 and ground.

Also check harness for short to power.

Is the inspection result normal?

YES 

>> GO TO 4.

NO

>> Repair open circuit or short to power in harness or con-

nectors.

4.

CHECK PARK/NEUTRAL POSITION SWITCH

1.

Turn ignition switch OFF.  (Stay for at least 5 seconds.)

2.

Remove park/neutral position switch. Refer to 

DLN-13, "Component Parts Location"

.

3.

Push and release park/neutral position switch and check conti-
nuity between park/neutral position switch terminals 1 and 2.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace park/neutral position switch.  Refer to 

DLN-13,

"Component Parts Location"

.
