3C-27 Transfer: Motor-Shift Type (Transfer with Shift Actuator)

Transfer Position Indicator Remains ON Steady at Ignition Switch ON

S5JB0E3314013

Wiring Diagram

Circuit Description
Transfer position indicator operates according to the signal from 4WD control module. If the transfer control system is 
in good condition, transfer position indicator light up for 2 seconds when ignition switch is turned to ON position, and 
then turned to OFF position. If an abnormality is detected in the system, transfer position indicator remains lighting.

1

Check DTC
1) Check DTC referring to “DTC Check: Motor-Shift Type 

(Transfer with Shift Actuator)”.

Is there any DTC(s)?

Perform DTC flow to 
repair and retry.

Go to Step 2.

2

CAN communication circuit check
1) Check CAN communication circuit between combination 

meter and 4WD control module referring to “DTC U1073: 
Control Module Communication Bus Off: Motor-Shift 
Type (Transfer with Shift Actuator)”.

Is CAN communication circuit in good condition?

Substitute a known-
good combination meter 
and recheck. If transfer 
position indicator still 
remains off, substitute a 
known-good 4WD 
control module and 
recheck.

Repair or replace.

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 switch circuit check
1) Disconnect transfer switch connector “G59” with ignition 

switch OFF.

2) Check for proper connection to “G59-2”, “G59-3” and 

“G59-4” terminals of transfer switch connector.

3) If connection is OK, measure voltage between “G59-2”, 

“G59-3” or “G59-4” terminal of transfer switch connector 
and vehicle body ground with ignition switch ON.

Is it 10 – 14 V?

Go to Step 3.

Go to Step 4.

Transfer switch check
1) Check transfer switch referring to “Transfer Switch 

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

Is switch in good condition?

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

Replace transfer switch.

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 “G59-2” terminal of transfer switch connector 

and “E91-18” terminal of 4WD control module 
connector 

• Between “G59-3” terminal of transfer switch connector 

and “E91-19” terminal of 4WD control module 
connector

• Between “G59-4” terminal of transfer switch connector 

and “E91-20” terminal of 4WD control module 
connector

Are they in good condition?

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

Repair circuit.
