When installing the steering wheel, and driver’s 
air bag module ensure that the harness of the 
clock spring does not become caught or tangled.
1. Before installing the steering wheel, and driver’s 

air bag module turn the vehicle’s front wheels to 
the straight-ahead position and align the mating 
marks of the clock spring.

2. After securing the steering wheel, turn the 

steering wheel all the way in both directions to 
confirm that the steering wheel rotation is normal.

>>D << COVER INSTALLATION

1. Secure the horn connector to the cover.
2. Install the cover to the steering wheel assembly.

>>E<< POST-INSTALLATION 
INSPECTION

1. Reconnect the negative (

−) battery cable.

2. Turn the ignition switch to “ON” position.

3. Does the "SRS" warning lamp illuminate for

AIR BAG MODULE CHECK

WARNING

•

If any component damage is found during 
the following inspection, replace the air 
bag module(s) with a new one. Dispose of 
the old one according to the specified 
procedure (Refer to 

P.52B-162

).

•

Never attempt to measure the circuit 
resistance of he air bag module (squib) 
even if you are using the specified tester. 
If the circuit resistance is measured with a 
tester, accidental air bag module(s) 
deployment will result in serious personal 
injury.

1. Check the pad cover for dents, cracks or 

deformation.

2. Check the connectors for damage, the terminals 

for deformation, and the harness for binds.

3. Check the air bag inflator case for dents, cracks or 

deformation.

4. Install the driver’s air bag module to the steering 

wheel and check fit and alignment with the wheel. 

5. Install the passenger’s (front) air bag module to 

the instrument panel and front deck crossmember 
and check fit and alignment.

CLOCK SPRING CHECK

If any malfunction is found in the following inspec-
tions, replace the clock spring with a new one.
1. Check the connectors and protective tube for 

damage, and the terminals for deformation.

2. Visually check the case for damage.
3. Check to see that there is a charge (continuity) 

between the B-137 clock spring connector 
terminal 1 and B-139 horn switch.

CAUTION

 Do not directly insert a probe, etc. into the termi-
nal from the front of the connector.
4.  Insert the special tool extra fine probe 

(MB992006) from behind the B-138 driver’s air 
bag module connector.

5.  As shown in the Figure, connect the circuit tester 

to the special tool extra fine probe (MB992006) 
and check to see that there is a charge between 
the terminals.
