DTC 12 Actuator Magnetic Clutch Circuit
CIRCUIT DESCRIPTION
This circuit turns on the magnetic clutch inside the actuator during cruise control operation according to the
signal from the ECU. If a malfunction occurs in the actuator or speed sensor, etc. during cruise control opera-
tion, the rotor shaft between the motor and control plate is released.
When the brake pedal is depressed, the stop light switch turns on, supplying electrical power to the stop light.
Power supply to the magnetic clutch is mechanically cut and the magnetic clutch is turned OFF.
When driving downhill, if the vehicle speed exceeds the set speed by 15 km/h (9 mph), the ECU turns the
safety magnet clutch OFF. If the vehicle speed later drops to within 10 km/h (6 mph), cruise control at the
set speed is resumed.

REMOVAL
NOTICE:

The hub bearing could be damaged if it is subjected
to the vehicle weight, such as when moving the ve-
hicle with the drive shaft removed.
Therefore, if it is absolutely necessary to place the ve-
hicle weight on the hub bearing, first support it with
SST.
SST 09608±16042 (09608±02021, 09608±02041)

After disconnecting the drive shaft from the axle hub,
work carefully so as not to damage the ABS speed
sensor rotor serration on the drive shaft.
1. REMOVE FRONT WHEEL AND FRONT FENDER
APRON SEAL
2. DRAIN ATF
3. REMOVE DRIVE SHAFT LOCK NUT
(a) Remove the cotter pin and lock cap.
(b) While applying the brakes, remove the nut.
4. DISCONNECT TIE ROD END FROM STEERING
KNUCKLE
(a) Remove the cotter pin and nut.
(b) Using SST, disconnect the tie rod end from the steering
knuckle.
SST 09610±20012
5. DISCONNECT LOWER SUSPENSION ARM FROM
LOWER BALL JOINT
Remove the bolt and 2 nuts, and disconnect the lower suspen-

(d) Using a brass bar and hammer, install the drive shaft.
NOTICE:
Be careful not to damage the dust cover of the drive shaft and oil seal lip of the transaxle.
HINT:
Whether the inboard joint shaft is in contact with the pinion shaft or not can be known from the sound or feel-
ing when driving it in.
(e) Check that there is 2 ± 3 mm (0.08 ± 0.12 in.) of play in the axial direction.
(f) Check that the drive shaft cannot be removed by hand.
2. RH drive shaft:
INSTALL DRIVE SHAFT TO TRANSAXLE
(a) Install the drive shaft.
NOTICE:
Be careful not to damage the dust cover of the drive shaft and oil seal lip of the transaxle.
(b) Using pliers, install a new snap ring.
(c) Install a new bearing lock bolt.
Torque: 32 N´m (330 kgf´cm, 24 ft´lbf)
3. CONNECT DRIVE SHAFT TO AXLE HUB
NOTICE:
Be careful not to damage the boot and ABS speed sensor rotor.
4. CONNECT LOWER SUSPENSION ARM TO LOWER BALL JOINT
Torque: 127 N´m (1,300 kgf´cm, 94 ft´lbf)
5. CONNECT TIE ROD END TO STEERING KNUCKLE
(a) Connect the tie rod end to the steering knuckle.
(b) Install the nut and a new cotter pin.
If the holes for the cotter pin are not aligned, tighten the nut further up to 60°.
Torque: 49 N´m (500 kgf´cm, 36 ft´lbf)
6. INSTALL DRIVE SHAFT LOCK NUT
(a) While applying brakes, install the nut.
Torque: 294 N´m (3,000 kgf´cm, 217 ft´lbf)
(b) Install the lock cap and a new cotter pin.
If the holes for the cotter pin are not aligned, tighten the nut further up to 60°.
7. FILL AND CHECK ATF (See page DI±133)
8. INSTALL FRONT FENDER APRON SEAL
9. INSTALL FRONT WHEEL
Torque: 103 N´m (1,050 kgf´cm, 76 ft´lbf)
10. CHECK FRONT WHEEL ALIGNMENT (See page SA±1)
11. CHECK ABS SPEED SENSOR SIGNAL (See page DI±177)

This TSB outlines the causes of brake vibration and pulsation, as well as the best corrective
measures to use.

1) Symptoms of brake vibration and pulsation
2) Cause of vibration/pulsation problems
3) Advantages of using an on±car brake lathe
4) Rotor replacement and off±car brake lathe procedure
1) SYMPTOMS OF BRAKE VIBRATION AND PULSATION
Brake vibration problems generally involve one or both of two phenomena: body vibration and/
or pedal pulsation.
A. BRAKE VIBRATION
Applying brakes causes vibration to occur in the instrument panel, steering column, steering
wheel, and/or body of the vehicle (See Figure 1 below).

BRAKE VIBRATION AND/OR PULSATIONPage 2 of 6
B. PEDAL PULSATION
Applying brakes causes the brake pedal to pulsate. This brake pulsation sometimes
causes the steering wheel to oscillate when the brakes are applied (See Figure 2 below).
2) CAUSE OF VIBRATION/PULSATION PROBLEMS
Brake rotor thickness variation causes brake vibration due to changes in the braking force as
thick/thin portions of the rotor pass the pads. Brake rotor thickness variation can be measured
with a micrometer as shown in Figure 3 below.
