Ecd System (W/ Dpf) - Initialization

Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 1VD-FTV ENGINE CONTROL


ECD SYSTEM (w/ DPF) - INITIALIZATION

INITIALIZATION PROCEDURE FOR DIESEL THROTTLE BODY ASSEMBLY, EGR VALVE ASSEMBLY AND TURBOCHARGER SUB-ASSEMBLY
  • HINT:
  • When the diesel throttle body assembly, EGR valve assembly or turbocharger sub-assembly is replaced, perform initialization

Turn the engine switch on (IG).

  • NOTICE:
  • Do not start the engine.

Turn the engine switch off and wait for 30 seconds or more.

Turn the engine switch on (IG) and wait for 10 seconds or more.

CATALYST RECORD OF DPF THERMAL DETERIORATION CLEAR FUNCTION
  • HINT:
  • When the front exhaust pipe assemblies (DPF catalytic converter) or monolithic converter assemblies (CCo catalytic converter) are replaced, the catalyst record of thermal deterioration stored in the ECM must be cleared.

Connect the GTS to the DLC3.

Turn the engine switch on (IG).

Turn the GTS on.

Press "Exit".

SUPPLY PUMP INITIALIZATION PROCEDURE
  • HINT:
  • After replacing the fuel supply pump assembly and/or ECM:
If the engine is defective or stalls immediately after startup, the learned values of the ECM must be initialized. The engine can be initialized through the GTS or by connecting DLC3 terminals.
If the engine starts normally, initialization is not necessary. Perform the steps labeled procedure "A" and procedure "B" only.

Press "Exit".

Start the engine to check if the initialization is complete. If the engine cannot be started, repeat the initialization procedures from the beginning (Procedure "A").

Idle the engine for at least 1 minute under the following conditions: (Procedure "B")

The engine coolant temperature is 60°C (140°F) or higher.
The fuel temperature is 20°C (68°F) or higher.
  • NOTICE:
  • Do not race the engine immediately after starting the engine. After warming up the engine, racing the engine is acceptable.
  • HINT:
The engine coolant temperature can be estimated by touching the outlet hose.
The fuel temperature can be estimated by using the ambient temperature as a substitute.
If the engine coolant temperature is difficult to estimate, use the GTS and enter the following menus: Engine and ECT / Data List / Coolant Temp.

Initialization is complete.

CRANK TIME COMPENSATION RESET FUNCTION
This procedure uses the GTS to perform "Crank Time Compensation Reset".
When replacing the timing rotor (engine assembly), perform "Crank Time Compensation Reset".
  • HINT:
Ecd System (W/ Dpf) - Initialization. 1VD-FTV ENGINE CONTROL. Land Cruiser URJ200 URJ202 GRJ200 VDJ200
If an error occurs during compensation reset, check the vehicle condition, and then perform compensation reset again.
A communication malfunction may occur if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.

Connect the GTS to the DLC3.

Turn the engine switch on (IG).

  • NOTICE:
  • Do not start the engine.

Turn the GTS on.

Enter the following menus: Engine and ECT / Utility / Crank Time Compensation Reset.

A/F SENSOR COMPENSATION RESET FUNCTION
This procedure uses the GTS to perform "A/F Sensor Compensation Reset".
When replacing the A/F sensor, replace the sensor and then perform "A/F Sensor Compensation Reset".
  • HINT:
Ecd System (W/ Dpf) - Initialization. 1VD-FTV ENGINE CONTROL. Land Cruiser URJ200 URJ202 GRJ200 VDJ200
If an error occurs during compensation reset, check the vehicle condition, and then perform compensation reset again.
A communication malfunction may occur if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.

Connect the GTS to the DLC3.
