Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
IHeadlamp switch is OFF,
I Air conditioner switch is OFF,
I Rear defogger switch is OFF,
I Steering wheel is in the straight-ahead position, etc.
BEFORE STARTING
1. Check service records for any recent
repairs that may indicate a related
problem, or the current need for
scheduled maintenance.
2. Open engine hood and check the fol- lowing:
I Harness connectors for improper con-
nections
I Vacuum hoses for splits, kinks, or
improper connections
I Wiring for improper connections,
pinches, or cuts
3.Using priming pump, bleed air from fuel system. Refer to ªFuel Filter Checkº in
MA section.
CONNECT CONSULT-II TO THE
VEHICLE.
Connect ªCONSULT-IIº to the data link
connector for CONSULT-II and select
ªENGINEº from the menu.
DOES ENGINE START?

CHECK INJECTION TIMING.
1. Set No. 1 piston at TDC on its com-pression stroke.
2. Remove injection tubes and air bleeder on the back of injection pump.
3. Set dial gauge so its indicator points to somewhere between 1.0 and 2.0 mm
(0.039 and 0.079 in) on the scale.
4. Turn crankshaft two turns clockwise and check that dial gauge indicates the
same value again.

Component Description
INJECTION TIMING CONTROL VALVE
The injection timing control valve is built into the fuel injection
pump. It controls the timer piston to change the fuel injection tim-
ing.
The timing control valve is a solenoid valve located in the line
between high-pressure chamber and low-pressure chamber. It
changes fuel pressure in the high-pressure chamber.
When current flows through the solenoid (the solenoid turns ON),
the timing control valve opens, advancing fuel injection timing.
When current does not flow through it, the timing control valve
closes, retarding injection timing.
The ECM emits an ON-OFF duty signal. The longer the OFF-
duration, the greater the advance angle. The longer the
ON-duration, the greater the retard angle. This means that chang-
ing the ON-OFF duty ratio makes it possible to achieve an optimal
advance angle and accurately control fuel injection timing.

Engine coolant temperature sensorEEngine coolant temperatureECMEGlow relayEGlow plugs
Ignition switchEStart signalEGlow lamp
IPre-glow
When the ignition switch is turned on the ON position, the glow
indicator lamp will turn ON and pre-glow starts.
The glow relay is turned ON continuously. The ON time of both
the glow indicator lamp and the glow relay is determined by the
engine coolant temperature. Pre-glow ends when the pre-glow
time elapses or when the engine is started.
I Intermediate glow
Intermediate glow starts when the pre-glow time has elapsed
and the engine has not been started. The glow relay is turned
ON intermittently. Intermediate glow ends when the intermedi-
ate glow time has elapsed, or when the engine is started.
I After-glow
After-glow starts as soon as the engine is running and the
engine coolant temperature is below 50ÉC (122ÉF). The glow
relay is turned on continuously. After-glow ends when the after-
glow time elapses, or when the engine coolant temperature
exceeds 50ÉC (122ÉF).

Set voltmeter between glow plug and engine body.
1. Pre-glow control
a. Turn ignition switch to ªONº position.
b. Read voltage and time.Battery voltage will continuously appear for about 20*
seconds after ignition switch is turned ªONº.
* Engine coolant temperature is higher than 20ÉC(68ÉF).
* Repeatedly turning the ignition switch to ªONº posi- tion and then back to ªLOCKº position may change
the glow time.
2. Intermediate-glow control
a. Turn ignition switch to ªLOCKº position. Wait at least 5 seconds.
b. Turn ignition switch to ªONº.
c. Read voltage. Battery voltage will intermittently appear for about 60
