DTC

C110000

Brake Pedal Position Sensor "A" Supply Voltage Malfunction

DESCRIPTION

The brake pedal stroke sensor assembly sends a signal about the pedal stroke to the skid control ECU.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Note
C110000	Brake Pedal Position Sensor "A" Supply Voltage Malfunction	When the voltage at terminal +BI1 is 7.3 V or more, the value of brake pedal stroke sensor 1 is invalid for 0.2 seconds or more.	Wire harness and connector Brake pedal stroke sensor assembly	Comes on	SAE Code: C1100 (Case 2) Output ECU: Both skid control ECUs

MONITOR DESCRIPTION

When the No. 2 skid control ECU (brake actuator assembly) detects that the value of brake pedal stroke sensor 1 is invalid, the MIL is illuminated and a DTC is stored.

MONITOR STRATEGY

Required Sensors/Components(Main)	Brake pedal stroke sensor assembly
Required Sensors/Components(Related)	No. 2 skid control ECU (brake actuator assembly) Brake pedal stroke sensor assembly
Frequency of Operation	Continuous
Duration	0.198 seconds
MIL Operation	Immediately
Sequence of Operation	None

TYPICAL ENABLING CONDITIONS

Monitor runs whenever the following DTCs are not stored	C1100 (Case 1): Brake pedal position sensor voltage circuit/open C14C7 (Case 3 to 9): Brake system voltage circuit low P057A: Brake pedal position sensor invalid data P057C: Brake pedal position sensor open circuit P057D: Brake pedal position sensor circuit high P057E: Brake pedal position sensor intermittent/erratic P05E0: Brake pedal position sensor "A"/"B" correlation
Both of the following conditions are met	-
Brake system voltage	Higher than 6.9 V
Brake pedal position sensor fail (C1100, P057C, P057D, P057E, P05E0, P057A)	Not detected

TYPICAL MALFUNCTION THRESHOLDS

Brake pedal position sensor state

Invalid

COMPONENT OPERATING RANGE

Both of the following conditions are met	-
Brake system voltage	Higher than 6.9 V
Brake pedal position sensor state	Valid

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. [*1]
Wait for 1 second or more. [*2]
HINT:

[*1] to [*2]: 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.	CHECK HARNESS AND CONNECTOR (BRAKE BOOSTER WITH MASTER CYLINDER ASSEMBLY - BRAKE PEDAL STROKE SENSOR ASSEMBLY)

(a) Make sure that there is no looseness at the locking part and the connecting part of the connectors.

OK:

The connector is securely connected.

(b) Disconnect the A104 No. 1 skid control ECU (brake booster with master cylinder assembly) connector.

*1: except TMC Made
*2: for TMC Made

(d) Check both the connector case and the terminals for deformation and corrosion.

OK:

No deformation or corrosion.

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

Standard Resistance:

except TMC Made

Tester Connection	Condition	Specified Condition
A104-3 (SKS1) - A103-6 (SKS1)	Always	Below 1 Ω
A104-3 (SKS1) or A103-6 (SKS1) - Body ground	Always	10 kΩ or higher

for TMC Made

Tester Connection	Condition	Specified Condition
A104-3 (SKS1) - A110-6 (SKS1)	Always	Below 1 Ω
A104-3 (SKS1) or A110-6 (SKS1) - Body ground	Always	10 kΩ or higher
