NO : 

Go to Step 3

STEP 3. M.U.T.-III actuator test
Use M.U.T.-III to perform the combination meter 
actuator tests.
Item No. 07: Indicator1

Q: Does the SRS warning lamp turn on and off 

normally?
YES : 

Go to Step 4

NO : 

Replace the combination meter (Refer to 
GROUP 54A

STEP 4. Check the diagnosis code. 
After erasing the diagnosis code memory, check the 
diagnosis code.

Q: Is the diagnosis code set?

YES : 

Troubleshoot for the relevant diagnosis 

code. (Refer to 

P.52B-13

.)

NO : 

Go to Step 5.

STEP 5. Recheck of the SRS warning lamp

Q: Does the lamp stay ON?

POST-COLLISION DIAGNOSIS

M1524001102416

Perform the inspection and service on post-collision 
vehicles according to the procedures below regard-
less of the deployment or activation statuses of air 
bags, lap pre-tensioner and seat belt pre-tensioner.

SRS-ECU MEMORY CHECK

1. Connect M.U.T.-III to the diagnosis connector 

(Refer to GROUP 00 

− How to Use 

Troubleshooting/Inspection Service Points ).

2. Use M.U.T.-III to read all the diagnosis codes.

POST-COLLISION DIAGNOSIS

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-120

NOTE: If the battery power is not supplied 
because of the collision impact, M.U.T.-III and 
SRS-ECU cannot communicate with each other. 
When this occurs, check or repair the instrument 
panel harness.

3. Erase the stored memory of diagnosis code, and 

then wait for 45 seconds or more to read the 
diagnosis code again. However, when the air bag 
has been deployed or if SRS-ECU is judged to be 
failure, do not erase the stored memory of 
diagnosis code.
