EASY AND SMOOTH START SYSTEM, Diagnostic DTC:C1382/21

DTC Code DTC Name
C1382/21 Clutch Stroke Sensor

DESCRIPTION

The clutch pedal stroke sensor assembly is installed to the upper part of the clutch pedal. It detects the amount that the clutch pedal is being depressed, and outputs a signal to the electric vehicle control ECU assembly.

The electric vehicle control ECU assembly memorizes the clutch release learning value.

DTC No. Detection Condition Trouble Area
C1382/21 When accelerating from 0 to 40 km/h, there is almost no change in the clutch pedal stroke sensor signal, and this occurs 5 times consecutively.

  • Harness or connector

  • Clutch pedal stroke sensor assembly

  • Electric vehicle control ECU assembly

INSPECTION PROCEDURE

Note


  • After replacing the electric vehicle control ECU assembly, perform clutch pedal stroke sensor assembly release position calibration Click here.

  • After replacing the clutch pedal stroke sensor assembly, perform clutch pedal stroke sensor zero point calibration and release position calibration Click here.

  • DTCs stored in the electric vehicle control ECU assembly are not cleared even after the system returns to a normal condition, so clear the DTCs after performing troubleshooting Click here.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (ELECTRIC VEHICLE CONTROL ECU ASSEMBLY - CLUTCH PEDAL STROKE SENSOR ASSEMBLY)


    1. Turn the ignition switch off.

    2. Disconnect the E42 electric vehicle control ECU assembly connector.

    3. Disconnect the C16 clutch pedal stroke sensor assembly connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      E42-22 (S+B) - C16-1 (C+B) Always Below 1 Ω
      E42-23 (S/S) - C16-2 (CSS) Always Below 1 Ω
      E42-24 (SGND) - C16-3 (C-S) Always Below 1 Ω
      E42-22 (S+B) or C16-1 (C+B) - Body ground Always 10 kΩ or higher
      E42-23 (S/S) or C16-2 (CSS) - Body ground Always 10 kΩ or higher
      E42-24 (SGND) or C16-3 (C-S) - Body ground Always 10 kΩ or higher

    5. Reconnect the E42 electric vehicle control ECU assembly connector.

    6. Reconnect the C16 clutch pedal stroke sensor assembly connector.

      *a

      Component with harness connected

      (to Electric Vehicle Control ECU Assembly)

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E42-22 (S+B) - Body ground Ignition switch ON 4.75 to 5.25 V
      E42-24 (SGND) - Body ground Ignition switch ON Below 1 V

    NG

    OK

  3. CHECK CLUTCH PEDAL STROKE SENSOR ASSEMBLY


    1. A01CHLVE02
      Text in Illustration
      *a

      Component with harness connected

      (to Electric Vehicle Control ECU Assembly)

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E42-23 (S/S) - Body ground

      Ignition switch ON

      Changes in proportion with the clutch pedal movement

      		 0.5 to 4.5 V
      OK
      The voltage varies in response to the clutch pedal stroke amount.

    NG

    REPLACE CLUTCH PEDAL STROKE SENSOR ASSEMBLY Click here

    OK

  4. READ VALUE USING INTELLIGENT TESTER


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.

      Note

      Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.

    4. Connect the intelligent tester to the DLC3.

    5. Turn the ignition switch to ON.

    6. Turn the intelligent tester on.

    7. Enter the following menus: Powertrain / Vehicle Control / Data List.

    8. According to the display on the intelligent tester, read the Data List.

      Vehicle Control
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
