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
