GLOW SYSTEM

GENERAL

OUTLINE OF CHANGES

The following maintenance service points have been established to correspond to the adoption of the
F9Q1 engine.

GENERAL INFORMATION

The glow system reduces the time required for starting at low temperatures to provide a degree of starting
and operation that is identical to petrol-engine vehicles by pre-heating the glow plugs at super-quick speed.
The engine-ECU controls both the time during which current is supplied to the glow plugs after the ignition
switch is turned to the ON position and also the glow indicator lamp illumination time in accordance with
the engine coolant temperature.
When the engine-ECU detects an abnormality in the glow system, it outputs diagnosis code (diesel fuel
system) in response to the abnormal item.

ON-VEHICLE SERVICE

GLOW SYSTEM CHECK

1.

Check that battery voltage is 11 – 13 V.

2.

Check that the engine coolant temperature is 40



C or

less.

3.

Measure the voltages at the glow plug circuits of each
cylinder.



For the No. 1 glow plug cylinder, measure between
glow relay box connector terminal (5) and earth.



For the No. 2 glow plug cylinder, measure between
glow relay box connector terminal (7) and earth.



For the No. 3 glow plug cylinder, measure between
glow relay box connector terminal (3) and earth.



For the No. 4 glow plug cylinder, measure between
glow relay box connector terminal (4) and earth.

4.

Measure the voltage immediately after the ignition switch is
turned to ON (without starting the engine).

Standard value:

9 – 11 V (Drops to 0 V after 0.5 – 16 seconds have
passed)

In addition, check to be sure that the glow indicator lamp
illuminates immediately after the ignition switch is turned
to ON.

NOTE
The voltage generated time (continuity time) varies
depending on the engine coolant temperature when the
ignition switch is ON.

5.

Measure the voltage while the engine is cranking.

Standard value: 6 V or more

6.

Start the engine and measure the voltage while the engine
is warming up.
The voltage always drops to 0 V when 10 – 60 seconds
have passed after starting the engine.

Standard value: 12 – 15 V

NOTE
The voltage generated time (continuity time) varies
depending on the engine coolant temperature when the
ignition switch is ON.
