4. Keyless start control module (if equipped)

[E]: Combination meter connector (viewed from harness side)

5. ECM

[F]: 4WD control module connector (viewed from harness side)

6. ABS hydraulic unit / control module

[G]: BCM connector (viewed from harness side)

7. Combination meter

[H]: DLC (viewed from harness side)

DTC detecting condition

Trouble area

Transmission error of communication data for 4WD control 
module is detected more than 7 times at more than specified 
error counts continuously.

• CAN communication circuit
• ECM
• BCM
• 4WD control module
• TCM
• Combination meter
• Keyless start control module (if equipped)
• ABS hydraulic unit / control module

Step

Action

Yes

No

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

Control module connector check
1) Check connection of connectors of all control modules 

communicating by means of CAN.

2) Recheck DTC in TCM.

Is DTC U1073 detected?

Go to Step 3.

Intermittent trouble. 
Check for intermittent 
referring to “Intermittent 
and Poor Connection 
Inspection in Section 
00”.

3

CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules 

communicating by means of CAN.

3) Check CAN communication circuit between control 

modules for open, short and high resistance.

Is each CAN communication circuit in good condition?

Go to Step 4.

Repair circuit.

4

Check DTC
1) Turn ignition switch to OFF position.
2) Disconnect each connector.

• ECM
• ABS hydraulic unit / control module
• BCM
• TCM (if equipped)
• Keyless start control module (if equipped)

3) Recheck DTC in 4WD control module.

Is DTC U1073 detected?

Check 4WD control 
module power and 
ground circuit. If circuits 
are OK, substitute a 
known-good 4WD 
control module and 
recheck.

Check applicable 
control module power 
and ground circuit. If 
circuit is OK, substitute 
a known-good 
applicable control 
module and recheck.

2) Start engine and run it for 1 min. or more.
3) Stop vehicle and check DTC.

Troubleshooting

DTC detecting condition

Trouble area

Reception error of communication data for ECM is detected for 
longer than specified time continuously.

• CAN communication circuit
• ABS hydraulic unit / control module
• ECM
• 4WD control module

Step

Action

Yes

No

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

DTC check
1) Check DTC in 4WD control module.

Is DTC U1100 and DTC U1073 detected together?

Go to “DTC U1073: 
Control Module 
Communication Buss 
Off: Motor-Shift Type 
(Transfer with Shift 
Actuator)”.

Go to Step 3.

3

DTC check
1) Check DTC in ECM.

Is DTC P1674 detected?

 Go to “DTC P1674: 
CAN Communication 
(Bus Off Error) in 
Section 1A”.

Go to Step 4.

4

Check each control module connectors
1) Check connection of connectors of all control modules 

communicating by means of CAN.

2) Recheck in 4WD control module.

 Is DTC U1100 detected?

Go to Step 5.

NO Intermittent trouble. 
Check for intermittent 
referring to “Intermittent 
and Poor Connection 
Inspection in Section 
00”.

5

CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules 

communicating by means of CAN.

3) Check CAN communication circuit between control 

modules for open, short and high resistance.

Is each CAN communication circuit in good condition?

Check ECM power and 
ground circuit. If circuit 
is OK, substitute a 
known-good ECM and 
recheck.

Repair circuit.
