MONITOR DESCRIPTION
P057A:
-
When the No. 2 skid control ECU (brake actuator assembly) detects that the difference between the brake pedal stroke sensor 1 and brake pedal stroke sensor 2 is invalid, the MIL is illuminated and a DTC is stored.
P05E0:
-
The No. 2 skid control ECU (brake actuator assembly) monitors the output value of the brake pedal stroke sensor assembly.
When the ratio between the output of brake pedal stroke sensor 1 and brake pedal stroke sensor 2 is outside the normal range, the No. 2 skid control ECU (brake actuator assembly) judges that the brake pedal stroke sensor assembly is malfunctioning, the MIL is illuminated and a DTC is stored.

CONFIRMATION DRIVING PATTERN
NOTICE:
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
-
Connect the GTS to the DLC3.
-
Turn the ignition switch to ON and turn the GTS on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the ignition switch off.
-
Turn the ignition switch to ON (READY) and turn the GTS on.
-
Fully depress the brake pedal. [*]
HINT:
[*]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Enter the following menus: Chassis / Brake/EPB / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
-
If the judgment result shows NORMAL, the system is normal.
-
If the judgment result shows ABNORMAL, the system has a malfunction.
-
If the judgment result shows INCOMPLETE, perform driving pattern again.

PROCEDURE
1.
|
READ VALUE USING GTS (BRAKE PEDAL STROKE SENSOR ASSEMBLY)
|
(a) Mount a pedal effort gauge.
(b) Turn the ignition switch to ON (READY) and depress the brake pedal once.
HINT:
Depress the brake pedal after turning the ignition switch to ON (READY) to set the vehicle to linear mode (switching solenoid (SSA) on).
(c) Depress the brake pedal slowly and check the brake pedal stroke sensor assembly output voltages with respect to brake pedal depression force.
