GLOW CONTROL SYSTEM

Diagnostic ProcedureEBS011FJ
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 and all glow plug connecting plate nuts 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. 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.
OK or NG
OK >> GO TO 4.
NG >> GO TO 5.

ant temperature sensor signal) and ground is above 3.62V.
If it is below 3.62V, cool down engine.
2. Turn ignition switch OFF.
3. Set voltmeter probe between glow plug and engine body.
4. Turn ignition switch ON.
5. Check the voltage between glow plug and engine body under
the following conditions.
OK or NG
OK >>INSPECTION END
NG >> GO TO 7.
5. CHECK DTC
Check that DTC U1000 is not displayed.
Ye s o r N o
Yes >> Perform trouble diagnoses for DTC U1000, refer to EC-944, "DTC U1000 CAN COMMUNICA-
TION LINE" .

ON BOARD DIAGNOSTIC (OBD) SYSTEMPFP:00028
DTC and MI Detection LogicEBS011X8
When a malfunction is detected, the malfunction (DTC) and freeze frame data are stored in the ECM memory.
The MI will light up each time the ECM detects malfunction. For diagnostic items causing the MI to light up,
refer to EC-1205, "
INDEX FOR DTC" .
Diagnostic Trouble Code (DTC)EBS011X9
HOW TO READ DTC
The DTC can be read by CONSULT-II only.
With CONSULT-II
CONSULT-II displays the DTC in "SELF-DIAG RESULTS" mode. Example: P0117, P0335, P1260, etc.
These numbers are prescribed by ISO15031-6.
(CONSULT-II also displays the malfunctioning component or system.)
HOW TO ERASE DTC
How to Erase DTC ( With CONSULT-II)
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2. Touch “ENGINE”.
3. Touch “SELF-DIAG RESULTS”.
4. Touch “ERASE”. (The DTC in the ECM will be erased.)
The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.
Freeze Frame DataEBS011XA
The ECM records the driving conditions such as calculated load value, engine coolant temperature, engine
speed, vehicle speed and intake manifold pressure at the moment a malfunction is detected.
The data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II. For
details, see EC-1253
.
Only one set of freeze frame data can be stored in the ECM. If freeze frame data is stored in the ECM memory
and another freeze frame data occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Freeze frame data (along with the DTCs) are cleared when the ECM memory is erased. Procedures for clear-
ing the ECM memory are described in EC-1223, "
HOW TO ERASE DTC" .
