STEP 2. Resistance measurement at C-119 joint 
connector (CAN1) and C-308 steering wheel 
sensor connector.

CAUTION

A digital multimeter should be used. For details 
refer to 

P.54C-7

.

CAUTION

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

P.54C-7

(1) Disconnect joint connector (CAN1) 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-7

.

(3) Ensure that the negative battery terminal is 

disconnected.

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 .

NO  : 

<Either or all of the resistances measure 
more than 2 

Ω> Repair the wiring harness 

between joint connector (CAN1) and the 
steering wheel sensor connector.

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 connected 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 G and yaw 
rate sensor" when the M.U.T.-III checks the periodi-
cally sent data from each ECU.

TROUBLE JUDGEMENT CONDITIONS
M.U.T.-III judges the trouble when the periodically 
sent data from G and yaw rate sensor cannot be 
received.
