POWER-ASSISTED STEERING SYSTEM 3B-55 

Check clearance between capsule and bracket. It must 
be less than 1 mm (0.039 in).

Column Universal Joint (between the
power steering unit and the steering shaft)

If resistance is felt when checked by rotating the joint, 
replace the lower second steering shaft. 
 

Shaft Universal Joint (between the lower 
second steering shaft and the second
steering shaft) 

If resistance is felt when checked by rotating the joint, 
replace the second steering shaft assembly. 
 

Tilt Mechanism 

The tilt mechanism should move smoothly. 
While locking the tilt mechanism, be sure the steering
column is latched securely by pushing the steering
wheel upward and downward. 
 

 

Installation 

1. Align the setting mark (1) on the second steering 

shaft and the steering column assembly (applied at 

disassembly). 

2.  Connect the steering column assembly to the second 

steering shaft. Tighten the bolts to the specified 

torque.

3. Thread the steering column assembly through the 

hole in the dashpanel. Temporarily tighten the 

steering column and the second steering shaft fixing 

bolts. 

4.  Align the setting marks (applied at disassembly) and 

connect the lower second steering shaft and the 

second steering shaft. Tighten the universal joint 

bolts to the specified torque.

⋅⋅⋅⋅m (3.2 kgf⋅⋅⋅⋅m/23 lb⋅⋅⋅⋅ft) 

5.  Tighten the steering column fixing bolt (pedal bracket 

side) to the specified torque (This bolt was 

temporarily tightened in Step 3). 

 

Torque: 20 N

⋅⋅⋅⋅m (2.0 kgf⋅⋅⋅⋅m/14 lb⋅⋅⋅⋅ft) 

6.  Tighten the second steering shaft fixing bolt to the 

specified torque (This bolt was temporarily tightened 

in Step 3) 

 

Torque: 20 N

⋅⋅⋅⋅m (2.0 kgf⋅⋅⋅⋅m/14 lb⋅⋅⋅⋅ft) 

7. Tighten the steering column fixing bolt (dashpanel 

side) to the specified torque (This bolt was 

temporarily tightened in Step 3). 

 

Torque: 20 N

8. Install combination switch and SRS coil assembly. 

After installation of combination switch assembly, 

connect the combination switch wiring harness 

connector and the SRS 2-way connector located 

under the steering column.

9. Turn the SRS coil fully counterclockwise, return 

about 3 turns and align the neutral mark (1). (with 

SRS air bag) 

CAUTION: When turning the SRS coil fully 
counterclockwise, stop turning if resistance is felt.
Further forced turning may damage to the cable in
the SRS coil.

10. When installing the steering column cover, be sure to

route each wiring harness as illustrated so that the

harnesses do not catch any moving parts.

11. 

Install steering wheel and align the setting marks 

made when removing. 

Refer to the adjustment method in case a mark has 

not been applied in this section. 

NOTE: Confirm SRS and horn harness connector is
fixed by the steering wheel.

CAUTION: Never apply force to the steering wheel in
the direction of the shaft by 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. 

12. Tighten the steering wheel fixing nut to the specified 

torque. 

 

Torque: 35 N

⋅⋅⋅⋅m (3.6 kgf⋅⋅⋅⋅m/26 lb⋅⋅⋅⋅ft) 

13. 

Support the module and carefully connect the 

module connector and horn lead, then install inflator 

module. 

NOTE: Pass the lead wire through the tabs on the
plastic cover (wire protector) of inflator to prevent lead
wire from being pinched. 
14. Tighten bolts to specified torque. 

 

Torque: 3 N

⋅⋅⋅⋅m (0.3 kgf⋅⋅⋅⋅m/26 lb⋅⋅⋅⋅in) 

15. Install driver knee bolster (reinforcement). 

16. Install instrument panel lower cover. 

17. Install the engine hood opening lever. 

18. Connect the yellow 2-way SRS connector and horn

lead located under the steering column. 

19. Connect the battery "-" terminal cable (with SRS air 

bag).
