SERVICEINSPECTION
SPEEDOMETER CHECK
(1) Assure tire pressure at standard value. (Refer to GROUP
- Specifications.)
(2)Gt the vehicle on a speedometer tester.
(3)Set free rollers securely on the floor according to the wheel-base and rear tread of the vehicle (when rear wheels
are to be set on free rollers).
(4) Raise the rear wheels on a jack and place rigid racks
to support the specified positions of the side sills (whenrear wheels are to be raised on a jack).
(5) Make sure the parking brake has been set.
cPWD>
(6)Attach anchoring bars on the tie-down brackets and secure
their ends to the anchor plates.(7) Make sure the tension on the right and left bars is the
same. Also be sure there is enough tension on each bar.(8) Attach a chain or wire to the rear tie-down hole. Make
sure the end of the wire or chain is secured firmly.
(9) Take all other necessary precautions.
(1O)Use a speedometer tester to measure the speedometer’s
indication error.

lVarious noises are produced de-pending on the body part of thevehicle.

and muffler, suspension,
etc.

Repair or replace electricalcomponents.
Return parts or wiring to
their proper position.
Caution
1.Connecting a high tension cable to the noise
filter may destroy the noise filter and shouldnever be done.
2.Check that there is no external noise. Since
failure to do this may result in misdiagnosis
due to inability to identify the noise source,
this operation must be performed.3. Noise prevention should be performed by
suppressing strong sources of noise step
by step.
NOTE
1. Condenser
The condenser does not pass D.C. current, butas the number of waves increases when it
passes A.C. current, impedance (resistanceagainst A.C.) decreases, and current flow is
facilitated. A noise suppressing condenser
which takes advantage of this property is in-
serted between the power line for the noise
source and the ground. This suppresses noiseby grounding the noise component (A.C. or
pulse signal) to the body of the vehicle.
2. Coil
The coil passes D.C. current, but impedance
rises as the number of waves increases relativeto the A.C. current. A noise suppressing coil
which takes advantage of this property is in-
serted into the power line for the noise source,
and works by preventing the noise componentfrom flowing or radiating out of the line.

Ground parts by bonding.
Cases where the problem
is not eliminated by a single
response to one area are
common, due to several
bodypartsbeing
imperfectly grounded.

ECU: Electronic Control Unit
NOTEIf the
lifigate unlock switch or door key cylinder unlock switch is operated roughly, or if these switches have
been installed incorrectly or switches themselves are defective the ECU may not accept the warning or alarmcancelling signal. In such case, the alarm operation will take place when the door is opened using a key.
[When the door key cylinder switch has been shorted, however, if the ignition switch is turned ON, the ECU
judges the detection-switch as faulty and thereafter, it will prevent setting of (warning) alarm until the shorting
is corrected.]
If the
liftgate is opened using a key and is left opened when the door key cylinder switch system has a trouble
(wiring harness damage, open circuit, etc.), the ECU judges it as the
liftgate holding mode and does not producealarm even when the door is opened.
