CAUTION:  Once the steering column is removed 
from the vehicle, the column is extremely 
susceptible to damage.  Dropping the column 
assembly on its end could collapse the steering 
shaft or loosen the slide block which maintains 
column rigidity.  Leaning on the column assembly 
could cause the jacket to bend or deform.  Any of 
the above damage could impair the column's 
collapsible design.  If it is necessary to remove the 
steering wheel, use only the specified steering 
wheel puller.  Under no conditions should the end of 
the shaft be hammered upon, as hammering could 
loosen the slide block which maintains column 
rigidity.

Removal

1. Turn the steering wheel so that the vehicle's wheels 

are pointing straight ahead.

2. Turn the ignition switch to “LOCK".

3. Disconnect the battery ground cable, and wait at 

least 5 minutes.

4. Disconnect the yellow 2-way SRS connector located 

under the steering column.

5. Loosen the inflator module fixing bolt from behind 

the steering wheel assembly using a TORX® driver 
or   equivalent until the inflator module can be 
released from steering assembly.

6. Disconnect the yellow 2-way SRS connector located 

behind the inflator module.

WARNING:  THE INFLATOR MODULE SHOULD 
ALWAYS BE CARRIED WITH THE TRIM COVER 
AWAY FROM YOUR BODY AND SHOULD   ALWAYS 
BE LAID ON A FLAT SURFACE WITH THE 
URETHANE SIDE UP.   THIS IS NECESSARY 
BECAUSE FREE SPACE IS PROVIDED TO ALLOW 
THE   AIR CUSHION TO EXPAND IN THE UNLIKELY 
EVENT OF ACCIDENTAL DEPLOYMENT.   
OTHERWISE, PERSONAL INJURY MAY RESULT.

7. Disconnect horn lead.

8. Remove steering wheel fixing nut.

9. Apply a setting mark (1) across the steering wheel 

and shaft so parts can be reassembled in their 
original position, then remove steering wheel.

10. Move the front wheels to the straight ahead position, 

then use steering wheel remover J–29752 to 
remove the steering wheel. 

CAUTION:  Never apply force to the steering wheel 
shaft using a hammer or other impact tools in an   
attempt to remove the steering wheel. The steering 
shaft is designed as an energy absorbing unit.

Installation

1. Install steering wheel by aligning the setting marks 

made when removing.

CAUTION:  Never apply force to the steering wheel 
shaft using a hammer or other impact tools in an   
attempt to remove the steering wheel. The steering 
shaft is designed as an energy absorbing unit.

2. Tighten the steering wheel fixing nut to the specified 

torque.

Torque: 34 N·m  (25 lb ft)

3. Connect horn lead.

4. Support the module and carefully connect the SRS 

connector.

NOTE:  Pass the lead wire through the tabs on the 
plastic cover (wire protector) of inflator to prevent lead 
wire from being pinches.

5. Tighten bolts to specified torque.

Torque: 9 N·m (78lb in)

6. Connect the yellow 2-way SRS connector located 

under the steering column.

7. Connect the battery “–" terminal cable.

8. Turn the ignition switch to the “ON" position and 

observe the warning lamp. The lamp should flash   7 
times. If the lamp does not operate correctly, refer to 
Restraints section.

Removal

1. Turn the steering wheel so that the vehicle's wheels 

are pointing straight ahead.

2. Turn the ignition switch to “LOCK".

3. Disconnect the battery ground cable, and wait at 

least 5 minutes.

4. Disconnect the yellow 2-way SRS connector located 

under the steering column.

CAUTION:  The wheels of the vehicle must be 
straight ahead and the steering column in the 
“LOCK" position before  disconnecting the steering 
wheel.  Failure to do so will cause the coil assembly 
to become uncentered which will cause damage to 
the coil assembly.

5. Remove the engine hood opening lever, then 

remove instrument panel lower cover.

6. Remove the driver knee bolster (reinforcement).
