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. Turn ignition switch ON.
2. Confirm that the voltage between ECM terminal 51 (engine cool-
ant temperature sensor signal) and ground is above 1.53V.
If it is 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.

with CONSULT-II or tester.
OK or NG
OK >> GO TO 9.
NG >> GO TO 8.
8. DETECT MALFUNCTIONING PART
Check the following.

60A fusible link

Harness for open or short between glow relay and battery
>> Repair harness or connectors.
9. CHECK GLOW RELAY OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 37 and glow relay terminal 2.

Component InspectionEBS011FK
GLOW RELAY
Check continuity between glow relay terminals 3 and 5 under the fol-
lowing conditions.
Operation takes less than 1 second.
GLOW PLUG
1. Remove glow plug connecting plate.
2. Check glow plug resistance.
NOTE:

Do not bump glow plug heating element. If it is bumped,
replace glow plug with a new one.

If glow plug is dropped from a height of 10 cm (3.94 in) or
higher, replace with a new one.

If glow plug installation hole is contaminated with car-
bon, remove it with a reamer or suitable tool.

Hand-tighten glow plug by turning it two or three times,
then tighten using a tool to specified torque.

BRAKE SWITCHPFP:25230
DescriptionEBS011FZ
STOP LAMP SWITCH
The stop lamp switch (1) is installed to brake pedal bracket. The
switch senses brake pedal position and sends an ON-OFF signal to
the ECM. The ECM uses the signal to control the fuel injection con-
trol system.
ASCD BRAKE SWITCH (MODELS WITH ASCD)
When depress on the brake pedal, ASCD brake switch is turned OFF and stop lamp switch is turned ON. ECM
detects the state of the brake pedal by this input of two kinds (ON/OFF signal)
Refer to EC-1339, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)" for the ASCD function.

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.
Diagnostic ProcedureEBS011G2
1. CHECK OVERALL FUNCTION-I
With CONSULT-II
1. Turn ignition switch ON.
2. Select “BRAKE SW” in “DATA MONITOR” mode with CON-
SULT-II.
3. Check “BRAKE SW” indication under the following conditions.
Without CONSULT-II
Check voltage between ECM terminal 100 and ground under the fol-
lowing conditions.
OK or NG
