Note

C110300

Brake Pedal Position Sensor "B" Supply Voltage Malfunction

When the voltage at terminal +BS is more than 8.5 V, the value of brake pedal stroke sensor 2 is invalid for 0.2 seconds or more.

  • Wire harness and connector
  • Brake pedal stroke sensor assembly

Comes on

  • SAE Code: C1103 (Case 2)
  • Output ECU: No. 2 skid control ECU (brake actuator assembly)

MONITOR DESCRIPTION

When the No. 2 skid control ECU (brake actuator assembly) detects that the value of brake pedal stroke sensor 2 is invalid, 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.
  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON and turn the GTS on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the ignition switch off.
  5. Turn the ignition switch to ON (READY) and turn the GTS on.
  6. Fully depress the brake pedal. [*1]
  7. 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.

  8. Enter the following menus: Chassis / Brake/EPB / Utility / All Readiness.
  9. 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 ACTUATOR 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 A105 No. 2 skid control ECU (brake actuator assembly) connector.

(c) Disconnect the A103*1 or A110*2 brake pedal stroke sensor 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:
