Система Ecd -- Меры Предосторожности |
- ПРИМЕЧАНИЕ:
- Replace the ECM, DPF catalyst and/or injector after the following operations:
| Replacement part | Operation |
| ECM |
|
| DPF catalyst | Clear DPF thermal deterioration data (See page Нажмите здесь) |
| Injector | Input injector compensation code (See page Нажмите здесь) |
| ECM and DPF catalyst |
|
| 1.CATALYST RECORD OF DPF THERMAL DETERIORATION |
- УКАЗАНИЕ:
- The ECM stores the history data of DPF catalyst thermal deterioration. 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 DPF catalyst is required based on the thermal deterioration data, the DTC is set to inform the driver.
When only the DPF catalyst is replaced.
After replacing the DPF catalyst, clear the thermal deterioration data stored in the ECM (See page Нажмите здесь).
When only the ECM is replaced.
After replacing the ECM, input the original thermal deterioration data stored before replacement (See page Нажмите здесь).
- ПРИМЕЧАНИЕ:
- Read the thermal deterioration data stored in the ECM before replacement, and store the data in the intelligent tester.
- If the thermal deterioration data cannot be read, be sure to replace the DPF catalyst with a new one and initialize the ECM (See page Нажмите здесь).
After replacing both the DPF catalyst and the ECM, clear the thermal deterioration data stored in the new ECM (See page Нажмите здесь).
- УКАЗАНИЕ:
- 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 set.
| 2.INJECTOR COMPENSATION CODE |
- УКАЗАНИЕ:
- Each injector has different fuel injection characteristics. In order to optimize fuel injection performance, the ECM compensates for these differences by adjusting the fuel injection duration of each injector according to its compensation code. Injector compensation codes are unique, 30-digit, alphanumeric values printed on the head portion of each injector.
- If an incorrect injector compensation code is input into the ECM, the engine may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.
When an injector is replaced, the injector's compensation code must be input into the ECM (See page Нажмите здесь).
When the ECM is replaced, all of the existing injector compensation codes must be input into the new ECM (See page Нажмите здесь).

| 3.DIFFICULT TO START ENGINE, ENGINE STALLING, OR BLACK SMOKE EMITTED |
Check if the customer's problem is described below. If so, refer to the troubleshooting section on the page given.
Engine is difficult to start or stalls (See page Нажмите здесь).
Black smoke is emitted (See page Нажмите здесь).
| 4.FOR USING INTELLIGENT TESTER |
- ПРЕДОСТЕРЕЖЕНИЕ:
- Observe the following items for safety reasons:
- Before using the tester, refer to the tester manuals.
- Prevent the tester cable from being caught on the pedals, shift lever and steering wheel when driving with the tester connected to the vehicle.
- When driving the vehicle for testing purposes using the tester, two persons are required. One is for driving the vehicle, and the other operates the tester.
| 5.EXPRESSIONS OF IGNITION SWITCH |
- УКАЗАНИЕ:
- The type of ignition switch used on this model differs according to the specifications of the vehicle.
- The expressions listed in the table below are used in this section.
| Expression | Ignition Switch (Position) | Engine Switch (Condition) |
| Ignition switch off | LOCK | Off |
| Ignition switch on (IG) | ON | On (IG) |
| Ignition switch on (ACC) | ACC | On (ACC) |
| Engine Start | START | Start |
