Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 1VD-FTV ENGINE CONTROL
ECD SYSTEM (w/ DPF) - PRECAUTION
| 1.INITIALIZATION AND REGISTRATION |
- NOTICE:
- When replacing the ECM and/or any other components in the following chart, perform the corresponding utility items.
- HINT:
- When the ECM and one or more other components are replaced at the same time, perform the following utility items by following the instructions shown on the GTS display, starting with the ECM.
| Replacement Part | Utility Item |
| ECM | Learning Values Save () Learning Values Write () |
| Engine assembly | Clear Crank Time Compensation Data () Input Injector Compensation Code () Pilot Quantity Learning () |
| Crankshaft position sensor plate | Clear Crank Time Compensation Data () |
| Air fuel ratio sensor | Clear A/F Sensor Compensation data () |
| Fuel supply pump assembly | Supply Pump Initialization () |
| Front exhaust pipe assemblies (DPF catalytic converter) | Clear DPF Thermal Deterioration Data () Learning Values Write () |
| Monolithic converter assemblies (CCo catalytic converter) | Clear DPF Thermal Deterioration Data () Learning Values Write () |
| Injector assembly | Input Injector Compensation Code () Pilot Quantity Learning () |
| Automatic transmission assembly, engine assembly or ECM | Automatic Transmission Initialization () |
- HINT:
- When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initializations/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.
| 2.INJECTOR COMPENSATION CODE |
- HINT:
When an injector assembly is replaced, the injector compensation code must be input into the ECM ().
| *1 | Injector Compensation Code |
| *a | Example |
When the ECM is replaced, all of the existing injector compensation codes must be input into the new ECM ().
| 3.CATALYST RECORD OF DPF THERMAL DETERIORATION |
- HINT:
- The ECM stores the thermal deterioration history data of the front exhaust pipe assemblies (DPF catalytic converter) and monolithic converter assemblies (CCo catalytic converter). This data is updated continuously and is then converted to an 8-digit code and is stored in the EEPROM. If the ECM determines that replacement of the front exhaust pipe assemblies (DPF catalytic converter) or monolithic converter assemblies (CCo catalytic converter) is required based on the thermal deterioration data, a DTC is stored to inform the driver.
When only the front exhaust pipe assemblies (DPF catalytic converter) are replaced.
After replacing the front exhaust pipe assemblies (DPF catalytic converter), clear the thermal deterioration data stored in the ECM ().
- HINT:
- Replace the DPF catalytic converter for bank 1 and bank 2 at the same time.
When only the monolithic converter assemblies (CCo catalytic converter) are replaced.
After replacing the monolithic converter assemblies (CCo catalytic converter), clear the thermal deterioration data stored in the ECM ().
When only the ECM is replaced.
After replacing the ECM, input the original thermal deterioration data stored before replacement ().
- NOTICE:
After replacing both the front exhaust pipe assemblies (DPF catalytic converter) and the ECM, clear the thermal deterioration data stored in the new ECM ().
- HINT:
- Clearing the thermal codes is required because initialization codes are stored in a new ECM. Failure to do this will cause a DTC to be stored.
| 4.PILOT QUANTITY LEARNING |
- HINT:
When an injector assembly is replaced, the injector compensation code must be input to the ECM, and then pilot quantity learning must be performed ().
When the ECM is replaced, all of the existing injector pilot quantity learning values must be input into the new ECM ().
| 5.ENGINE DIFFICULT TO START, ENGINE STALLING, BLACK SMOKE EMITTED, ROUGH IDLING, EXCESSIVE ENGINE VIBRATION, ENGINE KNOCKING, LACK OF POWER OR HESITATION |
Check if the customer problem is described below. If so, refer to the appropriate troubleshooting section.
Engine is difficult to start or stalling.
Black smoke is emitted.
There is rough idling or excessive engine vibrations.
There is engine knocking or rattling.
There is a lack of power or hesitation.
| 6.WHEN USING GTS |
- CAUTION:
