Short pin

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 C-119 joint 
connector (CAN1) and C-144 G and yaw rate 
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

OK: Continuity (2 

 or less) 

CAUTION

Strictly observe the specified wiring harness 
repair procedure. For details refer to 

P.54C-7

.

Q: Is the check result normal?

YES : 

<All the resistances measure 2 

Ω or less> 

Power supply to the G and yaw rate sensor 
may be suspected. Diagnose the G and yaw 
rate sensor.

NO  : 

<Either or all of the resistances measure 
more than 2 

Ω> Repair the wiring harness 

between joint connector (CAN1) and the G 
and yaw rate sensor connector.
