Wiring Diagram

DTC Detecting Condition and Trouble Area

DTC Confirmation Procedure

1) Clear DTC using scan tool.
2) Select transfer switch to “4H” position and keep its position for 10 seconds. Similarly select transfer switch to “4H-

lock”, “N” and “4L-lock” position.

3) Check DTC.

1

Was “4WD control system check” performed?

Go to Step 2.

Go to “4WD Control 
System Check: Motor-
Shift Type (Transfer with 
Shift Actuator)”.

2

Transfer shift actuator motor position switch circuit 
check
1) Disconnect transfer shift actuator connector “C54” with 

ignition switch OFF.

2) Check for proper connection to “C54-2”, “C54-3” and 

“C54-5” terminals of transfer shift actuator connector.

3) If connection is OK, measure voltage between “G54-2”, 

“G54-3” or “G54-5” terminal of transfer switch connector 
and vehicle body ground with ignition switch ON.

Is it approx. 5 V?

Go to Step 3.

Go to Step 4.

3

Transfer shift actuator position switch check
1) Check transfer shift actuator position switch referring to 

“Transfer Assembly Inspection: Motor-Shift Type 
(Transfer with Shift Actuator)”.

Is actuator in good condition?

Substitute a known-
good 4WD control 
module and recheck.

Faulty actuator position 
switch. Replace transfer 
shift actuator.

4

Wire harness check
1) Disconnect connector from 4WD control module 

connector “E91” with ignition switch OFF.

2) Check for open and high resistance in related circuits.

• Between “C54-2” terminal of transfer shift actuator 

connector and “E91-25” terminal of 4WD control 
module connector

• Between “C54-3” terminal of transfer shift actuator 

connector and “E91-26” terminal of 4WD control 
module connector

• Between “C54-5” terminal of transfer shift actuator 

connector and “E91-24” terminal of 4WD control 
module connector

Are they it in good condition?

Substitute a known-
good 4WD control 
module and recheck.

Repair circuit.
