CAUTION

• Always align the center of the clock spring before installing the steering wheel sensor. Otherwise, 

the sensor can be damaged.

• If the center of the clock spring is not correctly aligned, the steering wheel may not be turned fully 

or the cable inside the clock spring may be broken, causing the SRS air bag to be inoperative or 
operated incorrectly.

• Before removing the steering wheel assembly and driver's air bag module, always refer to GROUP 

52B − Service Precautions 

P.52B-24

 and Driver's Air bag Module and Clock Spring 

P.52B-413

.

• When the steering wheel sensor is replaced, always carry out calibration to make ASC-ECU learn 

the neutral point. (Refer to 

P.35C-289

.)

Pre-removal operation
• Position the front wheels in a straight ahead direction.
• Driver's air bag module removal (Refer to GROUP 52B −

.)

• Steering column upper cover and steering column lower 

cover removal (Refer to GROUP 37 − Steering Shaft 

P.37-33

WHEEL SENSOR

CAUTION

• Always align the center of the clock spring before 

installing the steering wheel sensor. Otherwise, the 
sensor can be damaged.

• If the center of the clock spring is not correctly aligned, 

the steering wheel may not be turned fully or the cable 
inside the clock spring may be broken, causing the 
SRS air bag to be inoperative or operated incorrectly.

1. Align the mating marks of the clock spring.

<Alignment of mating marks>

(1) Turn the clock spring clockwise fully.
(2) Turn the clock spring counterclockwise approximately 

three and 3/4 turns to align the mating marks.

(3) Check that the white roller is visible from the window for 

checking the neutral point with the mating marks being 
aligned.
NOTE: If the white roller is invisible, the neutral point is 
not positioned correctly.

CAUTION

Always align three mating marks of the steering wheel 
sensor simultaneously as shown in the figure. If these mat-
ing marks are not aligned correctly, the steering wheel 
sensor may be damaged.
2. Align three mating marks of the steering wheel sensor 

simultaneously as shown in the figure.
<Alignment of mating marks>

(1) Check the window for inspecting the neutral position of 

the steering wheel sensor. If the mating marks cannot be 
seen from the window, align the mating marks as shown 
in the figure. 

(2) Install the steering wheel sensor to the column switch 

assembly, maintaining the neutral position correctly.
NOTE: A new steering wheel sensor has a lock clip for 
preventing the rotation of (fixing) the steering wheel sen-
sor. After installing the column switch assembly, remove 
this lock clip.

(3) Install the column switch assembly to the vehicle, 

maintaining the neutral position correctly.

PARKING BRAKE DIAGNOSIS

INTRODUCTION

M1361003700345

If the parking brake is faulty, parking brake effort will 
become insufficient. The cause may be a malfunc-
tion of parking brake parts or the parking brake lever 
being out of adjustment.

TROUBLESHOOTING STRATEGY

M1361003800353

Use these steps to plan your diagnostic strategy. If 
you follow them carefully, you will be sure that you 
have exhausted most of the possible ways to find a 
parking brakes fault.
1. Gather Information from the customer.

2. Verify that the condition described by the 

customer exists.

3. Find the malfunction by following the Symptom 

Chart.

4. Verify malfunction is eliminated.
