READ VALUE USING GTS (VEHICLE SPEED)

CHECK COMBINATION METER SYSTEM

CHECK HARNESS AND CONNECTOR (ECM - COMBINATION METER)

DESCRIPTION

HINT:

1. Various systems use the vehicle speed signal distributed from the combination meter. Check all the components possibly related to speed signal.
   
2. A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter assembly.
   The signal is changed to a pulse signal at the transistor in the combination meter assembly. Each ECU controls the respective system based on the pulse signal.
   
3. If a short occurs in any of the ECUs or in the wire harness connected to an ECU, all systems using the speed signal will not operate normally.

CONFIRMATION DRIVING PATTERN

1. Connect the GTS to the DLC3.
   
2. Turn the ignition switch to ON and turn the GTS on.
   
3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
   
4. Turn the ignition switch off and wait for at least 30 seconds.
   
5. Turn the ignition switch to ON and turn the GTS on [A].
   
6. Start the engine.
   
7. On the GTS, enter the following menus to check the fuel-cut status: Powertrain / Engine and ECT / Data List / Idle Fuel Cut.
   
8. Drive the vehicle at 24 km/h (15 mph) or more for a total of 30 seconds or more [B].
   
9. Decelerate the vehicle by releasing the accelerator pedal for 5 seconds or more to perform the fuel-cut [C].
   
10. Stop the vehicle.
    
11. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].
    
12. Read the pending DTCs.
    

    HINT:

    1. If a pending DTC is output, the system is malfunctioning.
       
    2. If a pending DTC is not output, perform the following procedure.
       
13. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
    
14. Input the DTC: P0500.
    
15. Check the DTC judgment result.
    
    

    GTS Display	Description
    NORMAL	DTC judgment completed System normal
    ABNORMAL	DTC judgment completed System abnormal
    INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions
    N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    1. If the judgment result shows NORMAL, the system is normal.
       
    2. If the judgment result shows ABNORMAL, the system has a malfunction.

INSPECTION PROCEDURE

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, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1. Connect the GTS to the DLC3.
   

2. Turn the ignition switch to ON.
   

3. Turn the GTS on.
   

4. Enter the following menus: Powertrain / Engine and ECT / Data List / Vehicle Speed.
   

5. Drive the vehicle.
   

6. Read the value displayed on the GTS.
   

   OK:

   Vehicle speeds displayed on GTS and speedometer display are equal.
   

1. Inspect the circuits that send vehicle speed signals to this system in the meter system (LandCruiser RM000002UD70E2X.html ).
   

2. During the inspection in the meter section, if there is an instruction to proceed to the next suspected area, proceed to the next step.
   

1. Disconnect the ECM connector.
   

2. Disconnect the combination meter connector.
   

3. Measure the resistance according to the value(s) in the table below.
   
   

   Standard Resistance:

   
   

   Tester Connection	Condition	Specified Condition
   G6-32 (+S) - G181-23 (SPD)	Always	Below 1 Ω
