On-Vehicle Inspection [12/2019 - ]: Procedure

INSPECT BRAKE PEDAL LOAD SENSING SWITCH (BRAKE PEDAL SUPPORT ASSEMBLY)

Make sure that there is no looseness in the locking part and the connecting part of the connector.
Disconnect the brake pedal load sensing switch (brake pedal support assembly) connector.
Check both the connector case and the terminal for deformation and corrosion.
OK

No deformation or corrosion.
NOTE:
- Do not remove the brake pedal load sensing switch from the brake pedal support assembly.
- When there is a malfunction in the brake pedal load sensing switch, replace the brake pedal support assembly.

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

Standard Resistance

Tester Connection	Condition	Specified Condition
1 (FSW-) - 2 (FSW+)	Brake pedal load sensing switch off (Brake pedal depressed)	950 to 1050 Ω
1 (FSW-) - 2 (FSW+)	Brake pedal load sensing switch on (Brake pedal released)	203 to 223 Ω

If the result is not as specified, replace the brake pedal support assembly.
