Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

  1. CHECK SPARK PLUG AND SPARK OF MISFIRING CYLINDER 

    NG: GO TO step   4

    OK: GO TO Next Step 

  2. CHECK HARNESS AND CONNECTOR (IGNITION COIL - ECM [IGF SIGNAL TERMINAL]) 
    1. Check harness and connector (see ELECTRONIC CIRCUIT INSPECTION PROCEDURE ).

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: GO TO Next Step 

  3. INSPECT ECM (IGF1 AND IGF2 VOLTAGE) 
    1. Disconnect the ignition coil connector.
    2. Turn the ignition switch ON.
    3. Measure the voltage of the E5 and E7 ECM connector.

      Standard voltage 

      TESTER CONNECTION SPECIFIED CONDITION CHART

      Tester Connection Specified Condition
      E5-24 (IGF1) - E7-1 (E1) 4.5 to 5.5 V
      E5-25 (IGF2) - E7-1 (E1) 4.5 to 5.5 V
    4. Reconnect the ignition coil connector.

    NG: REPLACE ECM

    OK: REPLACE IGNITION COIL 

  4. CHECK HARNESS AND CONNECTOR (IGNITION COIL - ECM [IGT SIGNAL TERMINAL]) 
    1. Check harness and connector (see ELECTRONIC CIRCUIT INSPECTION PROCEDURE ).

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: GO TO Next Step 

  5. INSPECT ECM (IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7 OR IGT8 VOLTAGE) 
    1. Measure the voltage of the E5 and E7 ECM connectors when the engine is cranked.

    Standard voltage

    OK: GO TO Next Step 

  6. INSPECT ECM (IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7 OR IGT8 VOLTAGE) 
    1. Disconnect the 11, 12, 13, 14, 15, 16,17 or 18 ignition coil connector.
    2. Measure the voltage of the E5 and E7 ECM connectors when the engine is cranked.

      Standard voltage
