54C-64

DIAGNOSIS PROCEDURE

STEP 1. Connector check: joint connector 
(CAN-HI) and steering wheel sensor connector

CAUTION

The strand end of the twist wire should be within 
10 cm from the connector. For details refer to 

P.54C-5

.

When checking the joint connector, ensure that its 
wiring harness side and its short pins are not dam-
aged.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector. Replace the 
joint connector as necessary.

STEP 2. Resistance measurement at joint 
connector (CAN-HI) and steering wheel sensor 
connector.

CAUTION

A digital multimeter should be used. For details 
refer to 

P.54C-5

.

CAUTION

The test wiring harness should be used. For 
details refer to 

P.54C-5

.

(1) Disconnect joint connector (CAN-HI) and the 

steering wheel sensor connector, and measure at 

the wiring harness side.

(2) Turn the ignition switch to the LOCK (OFF) 

position.

CAUTION

When measuring the resistance, disconnect the 
negative battery terminal. For details refer to 

P.54C-5

.

(3) Ensure that the negative battery terminal is 

disconnected.

terminal No.6 and steering wheel sensor 
connector terminal No.3

OK: Continuity (2 

 or less) 

(5) Continuity between joint connector (CAN-HI) 

terminal No.17 and steering wheel sensor 
connector terminal No.4

OK: Continuity (2 

 or less) 

Q: Is the check result normal?

YES : 

<All the resistances measure 2 

Ω or less> 

Power supply to the steering wheel sensor 
may be suspected. Diagnose the steering 
wheel sensor. Refer to GROUP 35C 

− 

Troubleshooting .

NO  : 

<Either or all of the resistances measure 
more than 2 

Ω> Repair the wiring harness 

between joint connector (CAN-HI) and the 
steering wheel sensor connector.

Diagnosis Item 12: Diagnose when the M.U.T.-III cannot receive the data sent by 4WD-ECU <4WD>.

CAUTION

When servicing a CAN bus line, earth yourself by 
touching a metal object such as an unpainted 
water pipe. If you fail to do, a component con-
nected to the CAN bus line may be broken.

FUNCTION

The diagnostic result demonstrates that "the 
M.U.T.-III cannot receive the sent data from the 
4WD-ECU" when the M.U.T.-III checks the periodi-
cally sent data from each ECU and cannot receive 
the 4WD-ECU data only.

sent data from 4WD-ECU cannot be received. 

PROBABLE CAUSES

• Damaged harness wires and connectors

• Power supply circuit malfunction of the 

4WD-ECU

• Malfunction of the 4WD-ECU

DIAGNOSIS PROCEDURE

STEP 1. Connector check: joint connector 
(CAN-HI) and 4WD-ECU connector

CAUTION

The strand end of the twist wire should be within 
10 cm from the connector. For details refer to 

P.54C-5

.

When checking the joint connector, ensure that its 
wiring harness side and its short pins are not dam-
aged.

Q: Is the check result normal?

YES : 

Go to Step 2.
