Nissan Terrano model r20 series 2004. Instruction — part 174
System Operation Check
Set voltmeter between glow plug and engine body.
1. Pre-glow control
a. Turn ignition switch to “ON” position.
b. Read voltage and time.
Battery voltage will continuously appear for about 20*
seconds after ignition switch is turned “ON”.
* Engine coolant temperature is higher than 20°C
(68°F).
* Repeatedly turning the ignition switch to “ON” posi-
tion and then back to “LOCK” position may change
the glow time.
2. Intermediate-glow control
a. Turn ignition switch to “LOCK” position. Wait at least 5 seconds.
b. Turn ignition switch to “ON”.
c. Read voltage.
Battery voltage will intermittently appear for about 60
seconds after pre-glow control time has elapsed.
3. After-glow control
Start engine and read voltage and time.
Battery voltage will appear for max. 10 minutes.
When engine coolant temperature is lower than 50°C
(122°F).

Component Inspection
GLOW RELAY
1. Check relay terminals

GLOW PLUG
1. Remove glow plug connecting plate.
2. Check each glow plug for continuity.
Continuity should exist:
Approximately 0.5
Ω
[at 25°C (77°F)]
I
If NG, replace glow plug.
3. Install glow plug connecting plate securely.
I
Do not bump glow plug heating element. If it is bumped,
replace glow plug with new one. [If glow plug is dropped
from a height above 10 cm (3.94 in), replace with new one.]
I
If glow plug installation hole is contaminated with carbon,
remove using a reamer or suitable tool.
I
Hand-tighten glow plug by turning it 2 to 3 times, then
tighten using a tool to specified torque.

Component Description
VEHICLE SPEED SENSOR (VSS)
The vehicle speed sensor is installed in the combination meter. It
contains a pulse generator which provides a vehicle speed signal
to the speedometer. The speedometer then sends a signal to the
ECM.

The almost 0 km/h (0 mph) signal from vehicle speed
sensor is sent to ECM even when vehicle is being
driven.

Overall Function Check
Use this procedure to check the overall function of the vehicle
speed sensor circuit. During this check, a DTC might not be con-
firmed.
WITH CONSULT-II
1) Jack up drive wheels.
2) Start engine.
3) Read vehicle speed sensor signal in “DATA MONITOR” mode
with CONSULT-II.
The vehicle speed on CONSULT-II should be able to exceed 10
km/h (6 mph) when rotating wheels with suitable gear position.
WITHOUT CONSULT-II
1) Jack up drive wheels.
2) Rotate drive wheel by hand.
3) Check voltage between ECM connector terminal
417
and body
ground with tester.
Voltage should vary between approx. 0 - Battery voltage.
