STEP 5. Check the wiring harness between joint connector 
(CAN1) C-105 and SRS-ECU connector C-37 for a short to 
ground. Measure the resistance at joint connector (CAN1) 
C-105.
(1) Disconnect joint connector (CAN1), and measure the 

resistance at the wiring harness side of joint connector 
(CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 8 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 21 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES : Go to Step 6.
NO :  Go to Step 27.

STEP 6. Check the wiring harness between joint connector 
(CAN1) C-105 and occupant classification-ECU connector 
D-39-2 for a short to ground. Measure the resistance at 
joint connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the 

resistance at the wiring harness side of joint connector 
(CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 11 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 24 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES (vehicles without hands free system) : Go to Step 8.
YES (vehicles with hands free system) : Go to Step 7.
NO  :  Go to Step 28.

STEP 7. Check the wiring harness between joint connector 
(CAN1) C-105 and hands free module connector C-11 for a 
short to ground. Measure the resistance at joint connector 
(CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the 

resistance at the wiring harness side of joint connector 
(CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 10 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 23 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES : Go to Step 8.
NO :  Go to Step 29.

STEP 8. Check the wiring harness between joint connector 
(CAN1) C-105 and A/C-ECU connector C-22 <vehicles with 
A/C> or heater control unit connector C-53 <vehicles 
without A/C> for a short to ground. Measure the resistance 
at joint connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the 

resistance at the wiring harness side of joint connector 
(CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 1 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 12 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES (vehicles without MMCS) : Go to Step 9.
YES (vehicles with MMCS) : Go to Step 10.
NO  :  Go to Step 30.
