On-Vehicle Inspection [03/2017 - 06/2017]: Procedure

  1. INSPECT COMBINATION METER ASSEMBLY 
    1. Inspect speedometer operation
      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 / ABS/VSC/TRAC / Data List.
      6. Read the Data List according to the display on the Techstream.

        Chassis > ABS/VSC/TRAC

        Techstream Indication (mph) Acceptable Range (mph)
        20 19.2 to 21.7
        40 39.5 to 42.3
        60 59.9 to 62.7
        80 80.2 to 83.4
        100 100.6 to 103.8
        120 121.1 to 124.3
        140 141.5 to 144.7

        OK

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

    2. Inspect tachometer operation
      1. Warm up the engine.
      2. Connect the Techstream to the DLC3.
      3. Turn the ignition switch to ON.
      4. Enter the following menus: Powertrain / Engine / Data List.
      5. Read the Data List according to the display on the Techstream.

        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.

        5000 4800 to 5200
        6000 (5750 to 6250)
        7000 6700 to 7300

        OK

        Tachometer reading is within the acceptable range at each engine speed.

    3. Check LED illumination (LED check)
      1. Check the illumination function of the warning or indicator lights listed below when turning the ignition switch to ON.

        OK

        Warning or Indicator Light Specified Condition
        Brake warning light Warning or indicator light comes on for about 3 seconds after turning the ignition switch to ON.
        Slip indicator light
        VSC OFF indicator light
