DTC DETECTION LOGIC

NOTE:
• Conditions for applying the diagnostic procedure to the stored DTCs:

The DTC is declared present after attempts have been made to start the engine.

• Special notes:

If the DTC is present, it will be difficult to start the vehicle, or even impossible when cold, or preheating will
be continuous and the heater plugs will deteriorate.

Diagnosis Procedure

INFOID:0000000000956057

1.

CHECK GLOW RELAY POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect glow relay harness connector.

3.

Turn ignition switch ON.

4.

Check the voltage between glow relay connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DETECT MALFUNCTIONING PART

Check the following.
• 80A fusible link (letter N)
• Harness for open and short between glow relay and battery

>> Repair open circuit or short to ground or short to power in harness or connectors.

3.

CHECK GLOW RELAY INPUT CIRCUIT FOR OPEN AND SHORT-I

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between glow relay harness connector and ECM harness connector.

4.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

4.

CHECK GLOW RELAY INPUT CIRCUIT FOR OPEN AND SHORT-II

1.

Check the continuity between glow relay harness connector and ECM harness connector.

DTC No.
