On-Vehicle Inspection [01/2019 - 03/2019]: Procedure

  1. INSPECT SPEEDOMETER 
    NOTE:
    • The combination meter assembly receives the vehicle speed signal from the skid control ECU (brake actuator assembly) via CAN communication. Therefore, perform the following inspection referring to values on the Data List of the skid control ECU (brake actuator assembly) because it is the source of the vehicle speed signal.
    • Data List values of the skid control ECU (brake actuator assembly) are used for this inspection. Therefore, make sure to perform this inspection after confirming that DTCs are not output.
    • If the tire size or tire inflation pressure is not within the specified range, or the tires are excessively worn, the speedometer indication error will increase. Therefore, make sure to perform this inspection after checking that the tire size, tire inflation pressure and tire wear are in the specified range.
    1. Warm up the engine.
    2. Connect the Techstream to the DLC3.
    3. Turn the ignition switch to ON.
    4. Turn the Techstream on.
    5. Enter the following menus: Chassis / Brake / Data List.
    6. Read the Data List according to the display on the Techstream.

      Chassis > Brake > Data List

      220 222.8 to 227.8

      OK

      Speedometer reading is within the acceptable range at each vehicle speed.

  2. INSPECT TACHOMETER 
    1. Warm up the engine.
    2. Connect the Techstream to the DLC3.
    3. Turn the ignition switch to ON.
    4. Turn the Techstream on.
    5. Enter the following menus:
      • Powertrain / Engine / Data List. (for M20A-FKS)
      • Powertrain / Engine and ECT / Data List. (for 2ZR-FAE)
    6. Read the Data List according to the display on the Techstream.
      1. for M20A-FKS

        Powertrain > Engine > Data List 

        Tester Display Measurement Item Range Normal Condition Diagnostic Note
        Engine Speed Engine speed Min.: 0 rpm, Max.: 16383 rpm 600 to 700 rpm: Idling (shift lever in P, engine warmed up and A/C off) When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.

        Powertrain > Engine > Data List 

        Tester Display
