YES : 

Go to Step 8.

NO : 

Repair the damaged harness wire, and 
install the air bag module (driver’s side) 
(Refer to GROUP 52B,  Driver’s, Front 
Passenger’s Air Bag Module(s) and Clock 
Spring 

P.52B-225

). Then go to Step 18.

STEP 8. Check the clock spring.

Refer to GROUP 52B,  Driver’s, Front Passenger’s 
Air Bag Module(s) and Clock Spring 

P.52B-225

.

Q: Is the check result normal?

YES : 

It can be assumed that this malfunction is 

intermittent, and install the air bag module 
(driver’s side) (Refer to GROUP 52B,  
Driver’s, Front Passenger’s Air Bag 
Module(s) and Clock Spring 

P.52B-225

). 

Then go to Step 18.

NO : 

Replace the clock spring and install the air 
bag module (driver’s side) (Refer to GROUP 
52B,  Driver’s, Front Passenger’s Air Bag 
Module(s) and Clock Spring 

P.52B-225

). 

Then go to Step 18.

STEP 9. Measure the voltage at auto-cruise 
control switch connector C-305.
(1) Turn the ignition switch to the "ON" position and 

the MAIN switch to the "ON" position.

(2) Measure the voltage between connector C-305 

terminal No.3 and earth.

OK: 0.5 V or less

(3) Turn the MAIN switch to the "OFF" position and 

the ignition switch to the "LOCK" (OFF) position.

Q: Is the check result normal?

YES : 

Go to Step 15.

NO : 

Go to Step 10.

STEP 10. Measure the voltage at engine-ECU 
connector C-114 <M/T> or engine-A/T-ECU 
connector C-114 <A/T>.
(1) Turn the ignition switch to the "ON" position and 

the MAIN switch to the "ON" position.

(2) Measure the voltage between engine-ECU 

connector C-114 <M/T> terminal No.146 or 
engine-A/T-ECU connector C-114 <A/T> terminal 

No.146 and earth.

OK: 0.5 V or less

(3) Turn the MAIN switch to the "OFF" position and 

the ignition switch to the "OFF" position.

Q: Is the check result normal?

YES : 

Go to Step 12.

NO : 

Go to Step 11.

STEP 11. Connector check: C-114 engine-ECU 
connector <M/T> or C-114 engine-A/T-ECU 
connector <A/T>

Q: Is the check result normal?

YES : 

Install the air bag module (driver’s side) 

(Refer to GROUP 52B,  Driver’s, Front 
Passenger’s Air Bag Module(s) and Clock 
Spring 

P.52B-225

). Then go to Step 17.

NO : 

Repair or replace the faulty connector, and 
install the air bag module (driver’s side) 
(Refer to GROUP 52B,  Driver’s, Front 
Passenger’s Air Bag Module(s) and Clock 
Spring 

P.52B-225

). Then go to Step 18.
