СИСТЕМА ECD - Цепь предпускового подогрева |
DESCRIPTION
The glow plug is mounted inside the engine combustion chamber. To ensure efficient engine starting with a cold engine, the ECM calculates a time interval of the current that needs to flow through the glow plug depending on the starting engine coolant temperature when the ignition switch is turned on (IG). The ECM then turns on the glow plug relay and permits the current to flow through the glow plug based on the ECM's calculated time. The glow plug relay is then heated, and enhances fuel combustion with a cold engine. This DTC will be set if the glow plug or the circuit is open.- УКАЗАНИЕ:
- These troubleshooting procedures are for: 1) difficult starting engine in cold weather, and 2) difficulty driving / vehicle malfunctions in cold weather immediately after the engine is started.
- After the engine is started, the ECM performs an "after-glow" for a certain period of time. In proportion to the actual engine coolant temperature, the time period varies. The after-glow reduces diesel engine knocking, white smoke emissions and engine noises when the engine is cold.

INSPECTION PROCEDURE
- ПРИМЕЧАНИЕ:
- After replacing the ECM, the new ECM needs registration (See page Нажмите здесь) and initialization (See page Нажмите здесь).
1.CHECK GLOW PLUG RELAY TERMINAL VOLTAGE (GREL TERMINAL) |
Remove the glow plug relay.
Turn the ignition switch on (IG).
Measure the voltage according to the value(s) in the table below.
- Standard voltage:
Tester Connection
| Switch Condition
| Specified Condition
|
A55-2 - Body ground
| Ignition switch on (IG)
| 11 to 14 V
|
Reinstall the glow plug relay.
2.INSPECT GLOW PLUG RELAY |
Remove the glow plug relay.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
3 - 4
| Battery voltage is not applied between terminals 1 and 2
| 10 kΩ or higher
|
3 - 4
| Battery voltage is applied between terminals 1 and 2
| Below 1 Ω
|
Reinstall the glow plug relay.
3.INSPECT FUSIBLE LINK BLOCK ASSEMBLY (GLOW PLUG) |
Remove the fusible link block assembly from the engine room relay block.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
1G-1 - 1O-1
| Always
| Below 1 Ω
|
Reinstall the fusible link block assembly.
| REPLACE FUSIBLE LINK BLOCK ASSEMBLY |
|
|
4.INSPECT GLOW PLUG ASSEMBLY (RESISTANCE) |
Disconnect the glow plug wire.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
Glow plug terminal - Body ground
| 20°C (68°F)
| Approximately 0.95 Ω
|
- УКАЗАНИЕ:
- If any of the glow plugs has an open circuit, the engine power will be insufficient only when the engine is cold.
- ПРИМЕЧАНИЕ:
- Exercise extreme care not to damage the glow plug pipes. Damaging them could cause an open circuit, or shorten the life of the glow plugs.
- Keep the glow plugs free of oil and fuel while cleaning.
- Wipe any oil off of the terminal and Bakelite washer with a clean, dry cloth during inspection.
- Do not apply more than 11 V to the glow plugs as it may cause an open circuit.
Reconnect the glow plug wire.
5.CHECK GLOW PLUG ASSEMBLY (INSTALLATION) |
Check the glow plug installation.
- OK:
- The glow plugs are installed securely.
- Момент затяжки:
- 12 Н*м{125 кгс*см, 9 фунт-сила-футов}
6.CHECK HARNESS AND CONNECTOR (GLOW PLUG RELAY - GLOW PLUG - BATTERY AND BODY GROUND) |
Remove the glow plug relay.
Disconnect the glow plug connector.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection
| Condition
| Specified Condition
|
A55-3 - B44-1
| Always
| Below 1 Ω
|
A55-4 - Positive (+) battery terminal cabled
| Always
| Below 1 Ω
|
A55-1 - Body ground
| Always
| Below 1 Ω
|
Reinstall the glow plug relay.
Reconnect the ECM connector.
| REPAIR OR REPLACE HARNESS OR CONNECTOR (GLOW PLUG RELAY - GLOW PLUG - BATTERY AND BODY GROUND) |
|
|
7.CHECK HARNESS AND CONNECTOR (GLOW PLUG RELAY - ECM AND BODY GROUND) |
Remove the glow plug relay.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard resistance (Check for open):
Tester Connection
| Condition
| Specified Condition
|
A55-2 - B31-56 (GREL)
| Always
| Below 1 Ω
|
- Standard resistance (Check for short):
Tester Connection
| Condition
| Specified Condition
|
A55-2 or B31-56 (GREL) - Body ground
| Always
| 10 kΩ or higher
|
Reinstall the glow plug relay.
Reconnect the ECM connector.
| REPAIR OR REPLACE HARNESS OR CONNECTOR (GLOW PLUG RELAY - ECM AND BODY GROUND) |
