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.

NOTE: When replacing the brake actuator assembly, perform zero point calibration (see CALIBRATION ).

HINT:

If DTC C1249/49 is output, repair it before repairing DTC C1267/67 based on the flowchart below.

READ VALUE OF INTELLIGENT TESTER (BRAKE PEDAL LOAD SENSING SWITCH)

Check the DATA LIST for proper functioning of the brake pedal load sensing switch.

Skid control ECU

ITEM REFERENCE

Item (Display)	Measurement Item / Range (Display)	Normal Condition	Diagnostic Note
BRAKE PEDAL SW	Brake pedal load sensing switch / ON or OFF	ON: Depressed brake pedal OFF: Released brake pedal	-

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

OK: Go to step 4

NG: GO TO NEXT STEP.

INSPECT BRAKE PEDAL LOAD SENSING SWITCH

NOTE:

Do not remove the brake pedal load sensing switch from the brake pedal.
When there is a malfunction in the brake pedal load sensing switch, replace the brake pedal.

Turn the ignition switch OFF.
Disconnect the brake pedal load sensing switch connector. (See Fig 1).

Measure the resistance of the switch.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Condition	Specified Condition
2 - 1	Brake pedal depressed (OFF)	0.95 to 1.05 kΩ
2 - 1	Brake pedal released (ON)	202.4 to 223.7 Ω

NG: REPLACE BRAKE PEDAL SUPPORT ASSEMBLY

OK: GO TO NEXT STEP.

CHECK WIRE HARNESS (SKID CONTROL ECU - BRAKE PEDAL LOAD SENSING SWITCH)

Disconnect the A19 ECU connector.

Measure the resistance of the wire harness side connectors.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Specified Condition
A19-7 (FSW+) - A2-2	Below 1 Ω
19-7 (FSW+) - Body ground	10 kΩ or higher
A2-1 - Body ground	Below 1 Ω

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: GO TO NEXT STEP.

RECONFIRM DTC

Clear the DTC (see DTC CHECK / CLEAR ).

Check if the same DTC is recorded (see DTC CHECK / CLEAR ).
