Diagnostic ProcedureEBS01KLO
1.INSPECTION START
Check fuel level, fuel supplying system, starter motor, etc.
OK or NG
OK >> GO TO 2.
NG >> Correct.
2.CHECK INSTALLATION
Check that glow plug nut (1) and all glow plug connecting plate nuts
(2) are installed properly.
OK or NG
OK >> GO TO 3.
NG >> Install properly.
3.CHECK GLOW INDICATOR LAMP OPERATION
With CONSULT-II
1. Turn ignition switch ON.
2. Select “COOLAN TEMP/S” in “DATA MONITOR” mode with
CONSULT-II.
3. Confirm that “COOLAN TEMP/S” indicates below 80°C(176°F).
If it indicates above 80°C(176°F), cool down engine.
4. Turn ignition switch OFF, wait at least 5 seconds and then turn
ON.
5. Make sure that glow indicator lamp is turned ON for 1.5 seconds
or more after turning ignition switch ON, and then glow indicator
lamp turned OFF.
Without CONSULT-II
1. Set the tester probe between ECM terminal 51 (engine coolant
temperature sensor signal) and ground.
2. Confirm that the voltage indicates above 1.53V. If it indicates
below 1.53V, cool down engine.
3. Turn ignition switch OFF, wait at least 5 seconds and then turn
ON.
4. Make sure that glow indicator lamp is turned ON for 1.5 seconds
or more after turning ignition switch ON, and then glow indicator
lamp turned OFF.
OK or NG
OK >> GO TO 4.

ECM Terminals and Reference ValueEBS01KLT
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

3. Remove EGR volume control valve from cylinder head.
4. Reconnect EGR volume control valve harness connector.
5. Turn ignition switch ON.
6. Perform “EGR VOL CONT/V” in “ACTIVE TEST” mode with CONSULT-II. Check that EGR volume control
valve shaft moves smoothly forward and backward according to the valve opening.
If NG, replace the EGR volume control valve.
