WIRING DIAGRAM

Refer to DTC P0545 (LandCruiser RM00000188D0AIX_03.html).

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (LandCruiser RM0000012XK0AUX.html) and initialization (LandCruiser RM000000TIN08HX.html).
HINT:
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2080, P2084 OR P242B)

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

  1. Read DTCs.

2.READ VALUE USING GTS (EXHAUST TEMPERATURE)

  1. Leave the vehicle as is for 1 to 2 hours with the engine stopped.

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Exhaust Temperature B1S1, Exhaust Temperature B1S2 and Exhaust Temperature B1S3.

  1. Record the exhaust temperature displayed on the GTS.

3.INSPECT EXHAUST GAS TEMPERATURE SENSOR

  1. Drive the vehicle for 5 minutes or more at a speed of 50 km/h (31.1 mph) or more.

  1. Stop the vehicle.

  1. Connect the GTS to the DLC3.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Exhaust Temperature B1S1, Exhaust Temperature B1S2 and Exhaust Temperature B1S3.

  1. Read the value.

    Result:

    Result
    		Proceed to
    Difference between Exhaust Temperature B1S1 recorded in "READ VALUE USING GTS (EXHAUST TEMPERATURE)" and Exhaust Temperature B1S1 checked after driving is within +/-15°C (27°F)
    		A
    Difference between Exhaust Temperature B1S2 recorded in "READ VALUE USING GTS (EXHAUST TEMPERATURE)" and Exhaust Temperature B1S2 checked after driving is within +/-15°C (27°F)
    Difference between Exhaust Temperature B1S3 recorded in "READ VALUE USING GTS (EXHAUST TEMPERATURE)" and Exhaust Temperature B1S3 checked after driving is within +/-15°C (27°F)
    Difference between exhaust temperature recorded in "READ VALUE USING GTS (EXHAUST TEMPERATURE)" and exhaust temperature checked after driving is equal to or greater than +/- 15°C (27°F)

4.REPLACE EXHAUST GAS TEMPERATURE SENSOR
HINT:
Replace the exhaust temperature sensor that changed a small amount in "INSPECT EXHAUST GAS TEMPERATURE SENSOR".

  1. Replace the exhaust gas temperature sensor (LandCruiser RM000005UK3000X.html).

  1. Replace the No. 2 exhaust gas temperature sensor (LandCruiser RM000005UK3000X.html).

  1. Replace the No. 3 exhaust gas temperature sensor (LandCruiser RM000005UK3000X.html).



NEXT
Go to step 6

5.REPLACE ECM

  1. Replace the ECM (LandCruiser RM0000013Z002DX.html).

6.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

  1. Leave the vehicle as is for 1 to 2 hours with the engine stopped.

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG) and turn the GTS on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Exhaust Temperature B1S1, Exhaust Temperature B1S2 and Exhaust Temperature B1S3.

  1. Drive the vehicle for 5 minutes or more at a speed of 50 km/h (31.1 mph) or more.

  1. Stop the vehicle.

  1. Connect the GTS to the DLC3.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Exhaust Temperature B1S1, Exhaust Temperature B1S2 and Exhaust Temperature B1S3.
