STEP 8. Check the harness for short circuit to ground 
between the SRS-ECU and the junction block.
(1) Disconnect SRS-ECU connector E-08, and measure at the 

wiring harness.

CAUTION

Do not insert a test probe into the terminal from its front 
side directly as the connector contact pressure may be 
weakened.
(2) Check for continuity between E-08 harness connector 

terminal 16 and body ground.
It should be open circuit.

Q: Is the circuit normal?

YES : Erase the diagnostic trouble code memory, and check 

the diagnostic trouble code. If DTC 41 sets, replace 
the SRS-ECU. (Refer to 

P.52Ba-31

.) Then go to Step 

10.

NO :  Go to Step 9.

STEP 9. Check the harness for short circuit ground 
between SRS-ECU connector E-08 (terminal No.16) and 
junction block connector D-210 (terminal No.2).
Q: Are harness wires between SRS-ECU connector E-08 

(terminal No.16) and junction block connector D-210 
(terminal No.2) in good condition?
YES : 
Go to Step 10.
NO :  Repair the harness wire between SRS-ECU 

connector E-08 and junction block connector D-210. 
Then go to Step 10.

STEP 10. Recheck for diagnostic trouble code.
Q: Is DTC 41 set?

YES : Return to Step 1.
NO :  The procedure is complete. (If no malfunctions are not 

found in all steps, an intermittent malfunction is 
suspected. Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction
