FRONT TOWING PICKUP
Caution
\‘i
d
This vehicle cannot be towed by a wrecker using sling-typeequipment to prevent the bumper from deformation.
If this vehicle is towed, use wheel lift or flat bed equip-
ment.The vehicle may be towed on its rear wheels for extended
distances provided the parking brake is released. It is recom-
mended that vehicles be towed using the front pickup
whenever possible.
REAR TOWING PICKUP
Caution
This vehicle cannot be towed by a wrecker using sling-typeequipment to prevent the bumper from deformation.
If this vehicle is towed, use wheel lift or flat bed equip-
\
ment.‘L*3Manual transaxle vehicles may be towed on the front wheels,
provided the transaxle is in neutral and the drive-line has not
been damaged. The steering wheel must be clamped in the
straight-ahead position with a steering wheel clamping device
designed for towing service use.
CautionDo not use steering column lock to secure front wheel
position for towing.
Automatic transaxle vehicle may be towed on the front wheels
at speeds not to exceed 50 km/h (30 mph) for a distances not to
exceed 30 km (18 miles).
CautionIf these limits cannot be met, the front wheels must be
placed on a tow dolly.
TOWING WHEN KEYS ARE NOT AVAILABLE
When a locked vehicle must be towed and keys are not
available, the vehicle may be lifted and towed from the front,
provided the parking brake is released. If not released, the rear
wheels should be placed on a tow dolly.

13-12FUEL SYSTEM - Troubleshooting
MALFUNCTION INDICATOR LIGHT INSPECTION
(1) Check that when the ignition switch is turned on, the lightilluminates for about 5 seconds and then goes out.
(2) If the light does not illuminate, check for open circuit in
dharness, blown fuse and blown bulb.
SELF-DIAGNOSIS
The engine control unit monitors the input/output signals (some
signals at all times and the others under specified conditions) ofthe engine control unit.
When it is noticed that an irregularity has continued for a
specified time or longer from when the irregular signal is
initially monitored, passing a certain number, the engine controlunit judges that an irregularity has occurred, memorizes the
malfunction code, and outputs the signal to the self-diagnosis
output terminal.
There are 21 diagnosis items, including the normal state, andthe diagnosis results can be read out with a voltmeter or
multi-use tester.Moreover, since memorization of the malfunction codes is
backed up directly by the battery, the diagnosis results are
memorized even if the ignition key is turned off. The malfunc-
tion codes will, however, be erased when the battery terminalor the engine control unit connector is disconnected.
The malfunction code can also be erased by turning on the
ignition switch and sending the malfunction code erase signalfrom the multi-use tester to the engine control unit.
CautionIf the sensor connector is disconnected with the ignition
_ _switch turned on, the malfunction code is memorized. Ind
this case, send the malfunction code erase signal from themulti-use tester to the engine control unit or disconnect
the battery terminal
(-) for 10 seconds or more, and the
diagnosis memory will be erased.
The 21 diagnosis items are provided as follows, and if plural
items are activated, they are all indicated sequentially from the
smallest code number.
CautionThe malfunction code for the ignition timing adjustment
signal is output when the line of the ignition timing
adjustment terminal is shorted to ground. Therefore, the
malfunction code is also output when the ignition timing
adjustment terminal is grounded to adjust the ignition
timing, but this does not show any abnormality.

SELF-DIAGNOSIS CHECKING
Self-diagnosis checking is performed when there has been an
automatic cancellation without cancel switch operation.
‘1 ’
NOTE‘LAEven when the ignition key is placed in the OFF position, all
diagnosis codes are stored and retained, until the battery cable
is disconnected, to make sure that the problems encountered
in the past can be checked.

WITH MULTI-USE TESTER(1) Read the self-diagnosis code.
(2) Refer to the diagnosis chart and repair the defective point.
(3) Clear the self-diagnosis codes by the following procedure.@ Place the ignition switch in the ON position.@ With the SET switch in the ON state, set the main
switch to ON. In less than 1
.O second thereafter, set the
RESUME switch to ON.@ With the SET switch in the ON state again, keep the
’stop light switch in the ON state for more than 5dseconds.@ Check the self-diagnosis code to verify that a normal
code is output.
WITH VOLTMETER
(1) Connect an analog voltmeter across the self-diagnosis
output terminal and ground terminal of the diagnosis
connector.
(2) Place the ignition switch and main switch in the ON
position.
(3) Read the self-diagnosis code on the basis of the deflection
of the pointer of the voltmeter.
(4) Refer to the diagnosis chart and repair the defective point.
(5) Clear the self-diagnosis codes in the same way as when a
multi-use tester is used.

is blocked by the stopper, turn down adjusting nut C in
the direction that the free travel of the inner cable is
reduced, and back off adjusting nut C the specified
number of turns just before intermediate link C begins
to move.
Amount adjusting nut C is to be backed off:
About l/2 turn [inner cable free travel0

travel of the inner cable of the throttle cable is reduced.
At the position where the lever of intermediate link B is
brought into contact with intermediate. link C, back off
adjusting nut B the specified number of turns.
Amount adjusting nut B is to be backed off:
About one turn [inner cable free travel 1 to 2 mm
(.04 to .08 in.)]@ Secure the throttle cable with the lock nut.@ Secure the adjusting bolt of the surge tank.@ Turn down adjusting nut A in the direction that the free
travel of the inner cable of the cruise control cable is
reduced. At the position where the lever of intermedi-

B, back off adjusting nut A the specified number of
turns.
Amount adjusting nut A is to be backed off:
About one turn [inner cable free travel 1 to 2 mm

TRANSMISSION OIL LEVEL INSPECTIONRefer to GROUP 00
- Maintenance Service.
TRANSMISSION OIL REPLACEMENTM22FCAI(1) Position vehicle on a flat level.
(2) Remove filler and drain plugs and allow the transmission oil
to drain.
(3) Refill the transaxle to the proper level with specified
transmission oil. The oil level should be the bottom of the oil
filler hole.
Transmission oil: Hypoid gear oil, SAE 75W-85W con-
forming to API classification GL-4 or
higherC2.3 liters (2.4 pts.)]
SPEEDOMETER CABLE REPLACEMENTMUFEALl
1.Correctly insert the adapter into the instrument panel, and
fasten the new speedometer cable.
2.Install the grommet so that, as shown in the illustration, the
cable attachment part and the projecting part are horizontal.
CautionThe cable arrangement should be made so that the
radius of cable bends is 150 mm (5.9 in.) or more.
3.At the transaxle end of the speedometer cable, the key joint
should be inserted into the transaxle, and the nut should be
securely tightened.
Caution
If the cable is not correctly and securely connected, it
may cause incorrect indication. by the speedometer, orabnormal noise. Be sure to connect it correctly.
