TSB Revision INSPECTION
l Check the rod and link plate for bending or damage.
l Check the rod adjustment lock nut for looseness.
CHECKING THE SENSOR TERMINAL VOLTAGE
Connect the height sensor to the body harness and then
check that each terminal voltage changes as shown in the
table below when, with the ignition key at the ON position,
the sensor’s link plate is turned.
NOTE
To check the sensor terminal voltage, one method which can
be used is to move the rod up and down while the sensor is
installed to the chassis.

SERVICE POINTS OF INSTALLATION
7. INSTALLATION OF REAR ROD ASSEMBLY
/ 3. FRONT
ROD ASSEMBLY
(1) Adjust the front and rear height sensors so that dimension A of the rod in the illustration is within
specification.
Rod assembly length (A)
Front254-255 mm (9.9-10.0 in.)
Rear 149.5-150.5
mm (5.89-5.93
in.)
Caution
1. When adjusting the length of the rod, adjust so that dimension
B is uniform
2.Height sensors must be installed so that the ball
joint at the rod end is at rocking centre.
(2) When installing the rear rod assembly, install the rear height sensor brackets so that the dimension
L in the
illustration. is the standard value.
Standard value (L): 314-316 mm
(12.3-12.4 in.)

SERVICE POINTS OF REMOVAL
1. REMOVAL OF THROTTLE POSITION SENSOR
Disconnect the harness connector, then remove the
throttle position sensor from the throttle body.
2.REMOVAL OF STEERING WHEEL ANGULAR-VELOCITY
SENSOR
Remove the pin terminal from the column switch connec-
tor, then remove the steering wheel angular-velocity sensor from the column switch.
Caution
1.The steering wheel angular-velocity sensor utilizes a
photo coupler and care should be paid to ensure
that no dust or grease are allowed to come into contact with it.
2. Be careful and ensure that the column switch side
slit panel is not bent nor oil allowed to come into
contact with it.
3. REMOVAL OF
G SENSOR
Disconnect the connection of the harness connector, and
then remove the
G sensor.
Cautio
n
When removing the
G sensor, take care not to drop it or
subject it to severe impact.
INSPECTION For information concerning the procedures for checking each
sensor, refer to the service adjustment procedures section
and to the troubleshooting guide.

SERVICE POINTS OF REMOVAL
4. REMOVAL OF CALIPER ASSEMBLYM?dGSAP
(1) Remove the lock pin, rotate the caliper assembly
upward, then remove the caliper assembly and secure
it with wire, etc.
Caution
The lock pin has a special grease applied to it, so be
sure not to wipe it off, and ensure that the lock pin
stays clean.
I
(2) After removing the caliper assembly, cover the guide pin with a cloth, etc.
8. REMOVAL OF PROPELLER SHAFT’ INSTALLATION BOLT AND NUT
Place mating marks on the differential carrier companion
flange and the propeller shaft flange yoke.
NOTE
The mating marks should be used as a reference for
re-installation.
9. REMOVAL OF SELF LOCKING NUT
(1) Before removing the self locking nuts, support the differential case with a transaxle jack.
(2) Remove the self locking nuts.
12. REMOVAL OF PARKING BRAKE CABLE AND REAR
SPEED SENSOR INSTALLATION BOLT
(1) Lower the transaxle jack slightly.
(2) Remove the parking brake cable and the rear speed sensor installation bolts.
NOTE
The task may be made easier by increasing the gapbetween the body and the crossmember.
