DESCRIPTION

УКАЗАНИЕ:

1. These troubleshooting procedures are for: 1) difficulty starting engine in cold weather, and 2) difficulty driving/vehicle malfunctions in cold weather immediately after the engine is started.
   
2. 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 noise when the engine is cold.

INSPECTION PROCEDURE

1. Disconnect the glow plug relay connector.
   

2. Measure the voltage according to the value(s) in the table below.
   

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   A55-4 - Body ground	Always	9 to 14 V

3. Connect the glow plug relay connector.
   

1. Disconnect the glow plug relay connector.
   

2. Turn the ignition switch to the ON position.
   

3. Measure the voltage according to the value(s) in the table below.
   

   Standard voltage:

   Tester Connection	Switch Condition	Specified Condition
   A55-1 - Body ground	Ignition switch ON	9 to 14 V

4. Turn the ignition switch off.
   

5. Reconnect the glow plug relay connector.
   

1. Disconnect the glow plug relay connector.
   

2. Measure the resistance according to the value(s) in the table below.
   

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   3 - 4	When battery voltage not applied to terminals 1 and 2	10 kΩ or higher
   3 - 4	When battery voltage applied to terminals 1 and 2	Below 1 Ω

3. Reconnect the glow plug relay.
   

1. Disconnect the glow plug relay connector.
   

2. Disconnect the glow plug connector.
   

3. Measure the resistance according to the value(s) in the table below.
   

   Standard resistance (check for open):

   Tester Connection	Condition	Specified Condition
   A55-3 - B44-1	Always	Below 1 Ω

   Standard resistance (check for short):

   Tester Connection	Condition	Specified Condition
   A55-3 or B44-1 - Body ground	Always	10 kΩ or higher

4. Reconnect the glow plug relay connector.
   

5. Reconnect glow plug connector.
   

1. Remove the glow plug connector.
   

2. 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)	0.55 to 0.68 Ω

   УКАЗАНИЕ:

   If any of the glow plugs has an open malfunction, the engine power is insufficient only when the engine is cold.

   ПРИМЕЧАНИЕ:

   1. 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.
      
   2. Keep the glow plugs free of oil and fuel while cleaning.
      
   3. Wipe any oil off of the terminal and Bakelite washer with a clean, dry cloth during inspection.
      
   4. Do not apply more than 11 V to the glow plugs as it may cause an open circuit.
      

3. Reinstall the glow plug connector.
   

1. Check the glow plug installation.
   

   OK:

   The glow plugs are installed securely.
   

   Torque:

   13 N*m (127 kgf*cm, 9 ft.*lbf)
   

1. Disconnect the glow plug relay connector.
   

2. Disconnect the ECM connector.
   

3. Measure the resistance according to the value(s) in the table below.
   

   Standard resistance (check for open):

   Tester Connection	Condition	Specified Condition
   A55-2 - A57-81 (GREL)	Always	Below 1 Ω

   Standard resistance (check for short):

   Tester Connection	Condition	Specified Condition
   A55-2 or A57-81 (GREL) - Body ground	Always	10 kΩ or higher

4. Reconnect the glow plug relay connector.
   

5. Reconnect the ECM connector.
   

1. Remove the fusible link block from the engine room relay block.
   

2. 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

3. Reinstall the glow fuse.
   

1. Remove the EFI No. 2 fuse from the engine room relay block.
   

2. Measure the resistance according to the value(s) in the table below.
   

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   EFI No. 2 fuse	Always	Below 1 Ω

3. Reinstall the EFI No. 2 fuse.
   

1. Disconnect the glow plug relay connector.
   

2. Remove the integration relay from the engine room relay block.
   

3. Measure the resistance according to the value(s) in the table below.
   

   Standard resistance (check for open):

   Tester Connection	Condition	Specified Condition
   A55-1 - 1N-8	Always	Below 1 Ω

   Standard resistance (check for short):

   Tester Connection	Condition	Specified Condition
   A55-1 or 1N-8 - Body ground	Always	10 kΩ or higher
