ELECTRIC PARKING BRAKE SYSTEM, Diagnostic DTC:C13B1/63

DTC Code DTC Name
C13B1/63 Stroke Sensor Malfunction

DESCRIPTION

for M/T:

The brake pedal stroke sensor (clutch pedal stroke sensor) inputs the clutch pedal stroke into the electric parking brake ECU.

DTC Code DTC Detection Condition Trouble Area
C13B1/63

Either condition is met:


  • The brake pedal stroke sensor (clutch pedal stroke sensor) signal exceeds the upper or lower failure threshold.

  • A defective brake pedal stroke sensor (clutch pedal stroke sensor) signal.

  • Brake pedal stroke sensor (Clutch pedal stroke sensor)

  • Harness or connector

  • Electric parking brake ECU (Parking brake with bracket actuator assembly)

CAUTION / NOTICE / HINT

Note


  • Before performing work, turn the ignition switch off and wait approximately 20 seconds to make sure that the parking brake cannot operate.

  • When replacing the parking brake with bracket actuator assembly or brake pedal stroke sensor (clutch pedal stroke sensor), perform zero point calibration Click here.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (ELECTRIC PARKING BRAKE ECU - BRAKE PEDAL STROKE SENSOR (CLUTCH PEDAL STROKE SENSOR))


    1. Disconnect the electric parking brake ECU connector.
