Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
  1. PREPARE FOR INSPECTION 
    1. Check that both of the following conditions are satisfied.
      • The brake fluid level in the brake master cylinder reservoir is correct.
      • The parking brake is released.

      HINT:

      When the ABS warning light remains illuminated, repair the malfunctions in the ABS system first.

  2. CHECK DTC FOR ABS 
    1. Check if any ABS DTCs are output (see DTC CHECK / CLEAR ).

      Result

      DTC is output B

    B: REPAIR CIRCUITS INDICATED BY OUTPUT DTCS 

    A: GO TO NEXT STEP. 

  3. CHECK CAN COMMUNICATION SYSTEM 
    1. Check if the CAN communication system DTC is output (see DIAGNOSIS SYSTEM ).

      Result 

      RESULT PROCEED

      Result Proceed to
      DTC is not output A
      DTC is output B

    B: REPAIR CAN COMMUNICATION SYSTEM 

    A: GO TO NEXT STEP. 

  4. INSPECT SKID CONTROL ECU CONNECTOR 
    1. Check if the skid control ECU connector is properly installed.

    2. Measure the resistance of the wire harness side connector.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Specified Condition
      A19-32 (GND1) - Body ground Below 1 Ω
      A19-1 (GND2) - Body ground Below 1 Ω
    3. Measure the voltage of the wire harness side connector.

      Standard voltage 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      A19-46 (IG1) - Body ground Ignition switch ON 10 to 14 V

    NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK: GO TO NEXT STEP. 

  6. READ VALUE OF INTELLIGENT TESTER (PARKING BRAKE SWITCH) 
    1. Using the DATA LIST, check for proper functioning of the parking brake switch.

      Skid control ECU 

      ITEM REFERENCE

      Item (Display) Measurement Item / Range (Display) Normal Condition Diagnostic Note
      PARKING BRAKE SW Parking brake switch / ON or OFF ON: Parking brake applied
      OFF: Parking brake released      		 -

      OK: When the parking brake lever is operated, the display changes as shown above. 

    NG: Go to step   10 

    OK: GO TO NEXT STEP. 

  7. INSPECT BRAKE FLUID LEVEL WARNING SWITCH 
    1. Remove the reservoir tank cap and strainer.
    2. Disconnect the brake fluid level warning switch connector.
    3. Measure the resistance of the switch.

      HINT:

      A float is placed inside the reservoir. Its position can be changed by increasing or decreasing the brake fluid level.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      1 - 2 Float up (Switch OFF) 10 kΩ or higher
      1 - 2 Float down (Switch ON) Below 1 Ω

      HINT:

      If there is no problem after the above check is finished, adjust the brake fluid level to the MAX level.

    NG: REPLACE BRAKE MASTER CYLINDER RESERVOIR SUB-ASSEMBLY 

    OK: GO TO NEXT STEP. 

  8. CHECK WIRE HARNESS (LEVEL WARNING SWITCH - COMBINATION METER AND BODY GROUND) 
    1. Disconnect the E19 combination meter connector. (See Fig 3).
    2. Disconnect the A8 switch connector.
    3. Measure the resistance of the wire harness side connectors.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Specified Condition
      E19-14 (SW) - A8-1 Below 1 Ω
      E19-14 (SW) - Body ground 10 kΩ or higher
      A8-2 - Body ground Below 1 Ω
