QOS4 PREHEATING SYSTEM
GENERAL DESCRIPTION
QOS4 preheating system features a quick-on glow plug
with thermometer control of the glowing time and the
afterglow time function.
The system consists of the ECM, indicator lamp, ECT
sensor, vehicle speed sensor, relay and temperature
self-control type glow plugs.With the employment of the ECT sensor, the glow time
changes according to the engine coolant temperature,
thus allowing optimum starting conditions to be
obtained.
The after glow time function is controlled by ECM.
NOTE:
Refer to DTC P0380 and P0381 of 6E section.

1 Inspection on Quick Heating Operation
1. Disconnect ECT-sensor connection on the
thermostat housing
Legend
(1) ECT Sensor
(2) EVRV
2. Connect the circuit tester between glow plug and
engine earth.
3. Inspect the following items with starter switch set to
ON position (but do not start the engine).
1) The glow indicator shall light for about 5 sec.
2) The circuit tester shall indicate power supply
voltage for 180 sec.
If above specifications are not satisfied, inspect
wire harness, glow relay and ECT-sensor. If
satisfied, inspect glow plug.2 Inspection on Afterglow Operation
1. Disconnect ECT-sensor connection on the
thermostat housing
Legend
(1) ECT Sensor
(2) EVRV
2. Connect the circuit tester between glow plug and
engine earth.
3. Inspect the following item with the engine started.
1) The circuit tester shall indicate about 12 volts
after 180 seconds of engine start.
•If above specifications are not satisfied, inspect
battery voltage, engine earth, wiring harness,
glow plug, and ECM.
