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 ProcedureINFOID:0000000001162619
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.
 Harness connectors E8, F8
 Harness for open or short between ECM and glow relay
 Harness for open or short between IPDM E/R and glow relay
 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.

ENGINE ASSEMBLY
 If items or work required are not covered by the engine section, follow the procedures in the applica-
ble sections.
 Always use the support point specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
 For supporting points for lifting and jacking point at rear axle, refer to GI-48, "
Garage Jack and
Safety Stand and 2-Pole Lift".
