СИСТЕМА ECD - ОСНОВНАЯ ПРОВЕРКА

  • УКАЗАНИЕ:
  • When a malfunction is not confirmed by the DTC (Diagnostic Trouble Code) check, troubleshooting should be carried out in all circuits considered to be possible causes of the problem. In many cases, by carrying out the basic engine check shown in the following flowchart, the location of the problem can be found quickly and efficiently. Therefore, using this check is essential when troubleshooting the engine.

1.CHECK BATTERY VOLTAGE
  • ПРИМЕЧАНИЕ:
  • Carry out this check with the engine stopped and ignition switch OFF.
  • Standard voltage:
  • OKNG

Система Ecd - Проверьте, Нет Ли Эпизодических Неисправностей

СИСТЕМА ECD - ПРОВЕРЬТЕ, НЕТ ЛИ ЭПИЗОДИЧЕСКИХ НЕИСПРАВНОСТЕЙ

  • УКАЗАНИЕ:
  • Intelligent tester only:
  • Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with an intelligent tester when the ECM is in check mode. In check mode, the ECM uses 1-trip detection logic, which is more sensitive to malfunctions than normal mode (default). Normal mode uses 2-trip detection logic.
Clear the DTC(s) (see page ).
Switch the ECM from normal mode to check mode using the intelligent tester (see page ).
Perform a simulation test (see page ).
Check and wiggle the harness(es), connector(s) and terminal(s) (see page ).

Система Ecd - Меры Предосторожности

Land Cruiser Prado GRJ150 TRJ150 TRJ155 KDJ150 TRJ155 LJ150 - СИСТЕМА УПРАВЛЕНИЯ ДВИГАТЕЛЕМ 5L-E

WHEN USING INTELLIGENT TESTER

WHEN USING BATTERY DURING INSPECTION

СИСТЕМА ECD - МЕРЫ ПРЕДОСТОРОЖНОСТИ

1.WHEN USING INTELLIGENT TESTER
  • ПРЕДОСТЕРЕЖЕНИЕ:
Observe the following items for safety reasons:
Read the tester's instructions prior to use.
Make sure that the tester cable is not caught on the pedals, shift lever or steering wheel when driving with the tester connected to the vehicle.
When driving the vehicle with the tester connected, make sure 2 people are present. One person should drive the vehicle and the other should operate the tester.
2.WHEN USING BATTERY DURING INSPECTION
While using the battery during inspections, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
