Toyota RAV4 Service Manual: Brake pedal load sensing switch

Description

The brake pedal load sensing switch is turned on when the brake pedal is depressed with force exceeding a predetermined level.

The skid control ecu detects if the brake pedal is depressed or not via this circuit.

Inspection procedure

Notice:

When replacing the brake actuator assembly, perform zero point calibration (see page bc-24).

Hint:

If dtc c1249/49 is output, repair it before repairing dtc c1267/67 based on the flowchart below.

  1. Read value of intelligent tester (brake pedal load sensing switch)

  1. Check the data list for proper functioning of the brake pedal load sensing switch.

Ok: on (brake pedal is depressed) appears on the screen.



  1. Inspect brake pedal load sensing switch

Notice:

  1. Turn the ignition switch off.
  2. Disconnect the brake pedal load sensing switch connector.
  3. Measure the resistance of the switch.

Standard resistance




  1. Check wire harness (skid control ecu - brake pedal load sensing switch)

  1. Disconnect the a19 ecu connector.
  2. Measure the resistance of the wire harness side connectors.

Standard resistance




  1. Reconfirm dtc

  1. Clear the dtc (see page bc-47).
  2. Check if the same dtc is recorded (see page bc-47).
