FRONT TOWING PICKUP
Caution
This vehicle cannot be towed by a wrecker using sling-type
equipment to prevent the bumper from deformation.
If this vehicle is towed, use wheel lift or flat bed
equipment.
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-type
equipment to prevent the axle beam from deformation. If this vehicle is towed, use wheel lift or flat bed
equipment.
Manual 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.
Caution
Do 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 mob) for a distances not
to exceed 30 km (18 miles).
Caution
If 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.

FUEL SYSTEM - Troubleshooting13-11
ON-BOARD DIAGNOSTIC-
The engine control module monitors the input/out-
put signals (some signals at all times and the others
under specified conditions) of the engine control
module.
When it is noticed that an irregularity has continued
for a specified time or longer from when the irregu- lar signal is initially monitored, passing a certain
number, the engine control module judges that an
irregularity has occurred, memorizes the diagnostic
trouble code, and outputs the signal to the on-board
diagnostic output terminal.
There are 15 on-board diagnostic items including
the normal state, and the diagnostic results can be
read out with a voltmeter or scan tool.
Moreover, since memorization of the diagnostic
trouble codes is backed up directly by the battery,
the diagnostic results are memorized even if the ig- nition key is turned off. The diagnostic trouble
codes will, however, be erased when the battery disconnected. In addition, beginning with the engine
control module of
1990 and later models, the diag-
nostic trouble codes are erased by turning on the
ignition switch and sending the diagnostic trouble
code erase signal from the scan tool to the engine
control module.
Caution
If the sensor connector is disconnected with
the ignition switch turned on, the diagnostic
trouble code is memorized. In this case, send
the diagnostic trouble code erase signal from
the scan tool to the engine control module or disconnect the battery terminal (-)
for 10 sec-
onds or more, and the diagnostic memory will
be erased.

READ OUT OF DIAGNOSTIC TROUBLE CODE
Precautions for operation
(1) When battery voltage is low, no detection of failure is possible. Be sure to check the battery for voltage and
other conditions before starting the test.
(2) On-board diagnostic item is erased if the battery or the engine control module connector is discon-
nected. Do not disconnect the battery before the di-
agnostic result is completely read.
Using Scan Tool
(1) Switch OFF the ignition switch.
(2) Connect the power-source terminal of the scan tool to the
cigarette lighter socket.
(3) Connect the scan tool to the data link connector. (4) Turn ignition switch to ON.
(5) Using the scan tool, read out and make a note of the
on-
board diagnostic output.
(6) Refer to the diagnostic chart, and repair the indicated loca-
tion of malfunction.
(7) Erase the diagnostic trouble code. (Refer to
P.13-17.)
