CRUISE CONTROL SYSTEM Clutch Switch Circuit

DESCRIPTION

When the clutch pedal is released, the ECM receives positive (+) battery voltage through the ECU-IG&GAUGE fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal 21(D)*1, 15(CLSW)*2 or 10(CLSW)*3 of the ECM. The ECM cancels cruise control when terminal 21(D)*1, 15(CLSW)*2 or 10(CLSW)*3 receives the signal.

INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT FUSE (ECU-IG&GAUGE)


    1. Remove the ECU-IG&GAUGE fuse from the driver side junction block.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      ECU-IG&GAUGE fuse Always Below 1 Ω

    NG

    REPLACE FUSE

    OK

  2. CHECK HARNESS AND CONNECTOR (ECM - BATTERY)


    1. A01E195E01

      Disconnect the E13*1, E27*2 or E6*3 ECM connector.

      *1: for 1GR-FE

      *2: for 1KD-FTV (for DPF)

      *3: for 1KD-FTV (except DPF)

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

      Standard Voltage
      for 1GR-FE
      Tester Connection Switch Condition Specified Condition
      E13-21 (D) - Body ground

      Ignition switch ON

      Clutch pedal depressed

      		 Below 1 V

      Ignition switch ON

      Clutch pedal released

      		 11 to 14 V
      for 1KD-FTV (for DPF)
      Tester Connection Switch Condition Specified Condition
      E27-15 (CLSW) - Body ground

      Ignition switch ON

      Clutch pedal depressed

      		 Below 1 V

      Ignition switch ON

      Clutch pedal released

      		 11 to 14 V
      for 1KD-FTV (except DPF)
      Tester Connection Switch Condition Specified Condition
      E6-10 (CLSW) - Body ground

      Ignition switch ON

      Clutch pedal depressed

      		 Below 1 V

      Ignition switch ON

      Clutch pedal released

      		 11 to 14 V

    NG

  3. INSPECT CLUTCH SWITCH ASSEMBLY


    1. A01DVP2E01

      Remove the clutch switch.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      1 - 2 Pin pushed Below 1 Ω
      Pin not pushed 10 kΩ or higher

    NG

    REPLACE CLUTCH SWITCH ASSEMBLY

    OK

  4. CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH)


    1. A01E2AXE01

      Disconnect the E13*1, E27*2 or E6*3 ECM connector.

      *1: for 1GR-FE

      *2: for 1KD-FTV (for DPF)

      *3: for 1KD-FTV (except DPF)

    2. Disconnect the C23 clutch switch connector.

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

      Standard Resistance
      for 1GR-FE
      Tester Connection Condition Specified Condition
      E13-21 (D) - C23-2 Always Below 1 Ω
      E13-21 (D) - Body ground Always 10 kΩ or higher
      for 1KD-FTV (for DPF)
      Tester Connection Condition Specified Condition
      E27-15 (CLSW) - C23-2 Always Below 1 Ω
      E27-15 (CLSW) - Body ground Always 10 kΩ or higher
      for 1KD-FTV (except DPF)
      Tester Connection Condition Specified Condition
      E6-10 (CLSW) - C23-2 Always Below 1 Ω
      E6-10 (CLSW) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - CLUTCH SWITCH)
