INSPECTION PROCEDURE

Explanation of Symptom

Starting Trouble

For good starting it is essential to have:

Sufficient cranking speed.

Properly operating engine preheating system.

Good quality fuel.

The fuel is ignited by the heat which is generated by compression pressure.
With problems such as a depleted battery, the crankshaft speed can become low, or if the engine compression is poor due to leakage, the compression pressure will not rise and there will be difficulty starting.
When the engine is cold, even if there is compression heat, it will escape from the combustion chamber. For this reason, when the engine is started when it is cold, the glow plugs heat the compressed air.
Also, after starting the engine, by charging the glow plugs for a fixed time set according to the engine coolant temperature, diesel knocking and white smoke are prevented. The quantity of fuel injected is determined by the fuel pressure and also the amount of time the injector assembly is open.

3.TAKE SNAPSHOT DURING STARTING AND IDLING (PROCEDURE 3)

Connect the GTS to the DLC3.

Turn the engine switch on (IG) and turn the GTS on.

Enter the following menus: Engine and ECT / Data List / All Data.

Take a snapshot when idling with no load after the engine is warmed up and when starting trouble is occurring.

HINT:

A snapshot can be used to compare vehicle data from the time of the malfunction to normal data and is very useful for troubleshooting. The data in the illustration below is that of a normal vehicle, but as the data varies between individual vehicles, this data should only be used for reference.

When there is trouble starting with a cold engine, take the snapshot when the engine is cold. Then warm up the engine (engine coolant temperature is 70°C (158°F) or higher) and after idling the vehicle for 1 minute (A/C off, electrical load off), take a snapshot of the data for 15 seconds while idling.

Take a snapshot when the problem is occurring, such as when the engine is cold. However, if the problem does not reoccur, it is acceptable to only take a snapshot after the engine is warmed up and when the engine is started.

If the installation procedure is not performed correctly, injector assemblies may become out of position, which may cause the injector assemblies to deteriorate, resulting in malfunctions.

If an injector assembly deteriorates and malfunctions, other problems such as knocking, rough idle, etc. may occur.

If an injector assembly becomes out of position, it is possible that the seal between the injector assembly and injection pipe may become incomplete, resulting in a fuel leak.

Go to step 30

A

20.REPLACE INJECTOR ASSEMBLIES OF ALL CYLINDERS

Replace the injector assemblies ().

NOTICE:

When replacing the injector assembly for a cylinder, always be sure to use a new injection pipe.

If the installation procedure is not performed correctly, injector assemblies may become out of position, which may cause the injector assemblies to deteriorate, resulting in malfunctions.

If an injector assembly deteriorates and malfunctions, other problems such as knocking, rough idle, etc. may occur.

If an injector assembly becomes out of position, it is possible that the seal between the injector assembly and injection pipe may become incomplete, resulting in a fuel leak.

Result	Proceed to
Except below	A
The values of Engine Speed Cyl #1 to #8 are within +/-10 rpm of each other.	B

Replace the injector assembly ().

NOTICE:

When replacing the injector assembly for a cylinder, always be sure to use a new injection pipe.

If the installation procedure is not performed correctly, injector assemblies may become out of position, which may cause the injector assemblies to deteriorate, resulting in malfunctions.

If an injector assembly deteriorates and malfunctions, other problems such as knocking, rough idle, etc. may occur.

If an injector assembly becomes out of position, it is possible that the seal between the injector assembly and injection pipe may become incomplete, resulting in a fuel leak.

NEXT

27.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

END

28.INSPECT INJECTOR DRIVER

Even in cases where DTC P062D and P062E are not stored even though the engine cannot be started, perform the DTC P062D troubleshooting procedure ().

HINT:

When the engine cannot be started due to a malfunction in the injector driver system, once the DTCs are cleared, the system cannot store DTC P062D and P062E even if it is confirmed that the engine cannot be started when trying to reproduce the problem symptoms.
As DTC P062D and P062E cannot be stored when starting the engine, fuel injection signals are output by the ECM, but fuel is not actually injected. Therefore, an excessive amount of fuel is supplied to the common rail by the fuel supply pump assembly, and as a result, the fuel pressure is higher than the target common rail pressure in the data recorded at the time the engine was having trouble starting.

If the problem cannot be determined even after performing the DTC P062D and P062E troubleshooting procedure and the fuel pressure is higher than the target common rail pressure when attempting to start the engine, proceed to the next step.
