Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK OPERATION OF SPEEDOMETER 
    1. Drive the vehicle and check if the function of the speedometer on the combination meter is normal.

      OK: Actual vehicle speed and the speed indicated on the speedometer are the same. 

      HINT:

      • The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, refer to "ON-VEHICLE INSPECTION " in the meter/gauge system (See DIAGNOSTIC TROUBLE CODE CHART ).
      • The vehicle speed sensor is functioning normally when the indication on the speedometer is normal.

    NG:  Go TO COMBINATION METER

    OK: Go to Next Step 

  2. INSPECT RADIO RECEIVER 
    1. Disconnect the radio receiver connector R2 (*1), R16 (*2).
    2. Measure the voltage.
      1. Jack up either one of the drive wheels.
      2. Move the shift lever to the neutral position.
      3. Turn the ignition switch to the ON position.

      4. Measure the voltage between terminal SPD of the wire harness connector and body ground when the drive wheels are turned slowly.

        OK: Voltage pulses as shown in the illustration.

        *2: for Separate Type Amplifier System

    OK: REPLACE RADIO RECEIVER 

    NG: Go to Next Step 

  3. CHECK HARNESS AND CONNECTOR (COMBINATION METER - RADIO RECEIVER) 
    1. Disconnect the radio receiver connector R2 (*1), R16 (*2) and combination meter connector C7.

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

      Standard resistance 

      STANDARD RESISTANCE SPECIFICATION

      Tester connection Condition Specified condition
      SPD - C7-36 Ignition switch off Below 1 Ω

      *1: for Built-in Type Amplifier System

      *2: for Separate Type Amplifier System

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to Next Step 

  4. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER - BODY GROUND) 
    1. Measure the resistance according to the value (s) in the table below.

      Standard resistance 

      STANDARD RESISTANCE SPECIFICATION

      Tester connection Condition Specified condition
      SPD - Body ground Ignition switch off 10 kΩ or higher

      HINT:

      If the resistance between terminal SPD and body ground is less than 10 kΩ, there may be a short in a wire harness, connector, or an ECU that is connected to the SPD signal wire.

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR OR EACH ECU 

    OK: REPLACE COMBINATION METER
