ON-VEHICLE INSPECTION
Charge the battery fully before starting the following
inspections.
A. If the magnetic switch dose not function dur-
ing starting.
1. Turn the ignition switch to the start position.
2. Measure the voltage between the S terminal and
ground.
3. If the measured value is standard voltage or more,
there is starter malfunction.
4. If it is less than standard voltage, there is a mal-
function in the wiring.
Standard voltage: 8 V
Caution
If the magnetic switch is hot, it may not func-
tion even though the voltage is standard volt-
age or more.
B.lf the starter won't crank, or if the cranking
speed is slow.
The problem may be a malfunction of the starter
or in the wiring.
Note
The cranking speed is greatly affected by the
viscosity of the engine oil.

inspection.
1. Turn the ignition switch to the start positron.
2. Check that the starter motor operates.
3. If the starter does not operate, check the voltage
between S terminal and ground using a voltmeter.
4. If the voltage is 8V or more, the starter is mal-
function.
5. If less than 8V, the wiring harness is malfunction.
Caution
If the magnetic switch is hot, it may not func-
tion even though the voltage is standard volt-
age or more.
Note
The cranking speed is greatly affected by the
viscosity of the engine oil.

QUICK START SYSTEM (QSS) 5
SYSTEM OPERATION
The Quick Start System has three functions: Pre-heating, Chopping, and After-glow; as used in
the previous model. Each function operates as follows:
1. Pre-heating After ignition switch is turned to ON position, current flows to glow plug for 6
sec.
2. Chopping While engine switch is in START position, current flows to glow plug con-
tinuously.
3. After-glow (coolant temperature below 30°C (86°F):
a) When engine switch is kept in ON position after pre-heating, current flows to
glow plug continuously for 15 sec.
b) After engine has stared, current flows to glow plug continuously for 15 sec.
Indicator lamp: Indicator illuminates for 3 sec. after ignition is ON position.
When ignition switch is ON-START-ON position
When ignition switch is kept in ON position

2. Ground the ground connector of the EC-AT
Tester.
3. Connect the 6-pin connector of the EC-AT Tester
to the service connector.
Note
The service connector is blue-colored con-
nector.
4. Ground the 1 pin service connector.
Note
The service connector is blue-colored con-
nector.
5. Turn the ignition switch ON.
6. Check that "88" flashes on the digital display and
the buzzer sounds for three seconds after turning
the ignition switch ON.
7. If "88" does not flash, check the service connec-
tor wiring.
8. If "88" flashes and the buzzer sounds continuously
for more than 20 seconds, check wiring to 2M ter-
minal of the EC-AT control unit for short-circuit then
replace the EC-AT control unit and repeat steps
3 and 4.
9. Note the code numbers and check for the causes
by referring to the Inspection Procedure shown on
pages 7B—19 to 7B—21, repair as necessary.
Note
After repairs are made, recheck for code num-
bers by performing the "After-repair
procedure."
