Brake Pedal (For Vacuum Brake Booster) On-Vehicle Inspection


  1. INSPECT BRAKE PEDAL LOAD SENSING SWITCH

Brake Pedal (For Vacuum Brake Booster) -- On-Vehicle Inspection



1. INSPECT BRAKE PEDAL LOAD SENSING SWITCH
HINT:
  1. Do not remove the brake pedal load sensing switch from the brake pedal lever sub-assembly.
  2. When there is a malfunction in the brake pedal load sensing switch, replace the brake pedal lever sub-assembly.
  3. The illustration below is for LHD vehicles. Check the brake pedal load sensing switch for RHD vehicles using the same procedure as for LHD vehicles.


  1. Disconnect the brake pedal load sensing switch connector.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    2 (FSW+) - 1(FSW-)
    		Brake pedal depressed
    		0.9 to 1.1 kΩ
    Brake pedal released
    		192 to 234 Ω
    If the result is not as specified, replace the brake pedal support assembly (LandCruiser RM000002W9007HX.html).
