VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1417

DTC Code DTC Name
C1417 High Power Supply Voltage Malfunction

DESCRIPTION

If a malfunction is detected in the power supply circuit, the brake actuator assembly (skid control ECU) stores this DTC and the fail-safe function prohibits ABS operation.

This DTC is stored when the IG1 terminal voltage deviates from the DTC detection condition due to a malfunction in the power supply or charging circuit such as the battery or generator circuit, etc.

The DTC is cancelled when the IG1 terminal voltage returns to normal.

DTC NO. DTC Detection Condition Trouble Area
C1417 The IG1 terminal voltage is 17.4 V or more for 0.8 seconds or more.

  • ECU-IG NO. 2 fuse

  • Battery

  • Charging system

  • Power source circuit

  • Internal power supply circuit of the skid control ECU

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

    2. Disconnect the A54 or A56 brake actuator assembly (skid control ECU) connector.

    3. Turn the ignition switch to ON.

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

      Standard Voltage
      except LHD with CVT
      Tester Connection Switch Condition Specified Condition
      A54-34 (IG1) - Body ground Ignition switch ON 11 to 14 V
      for LHD with CVT
      Tester Connection Switch Condition Specified Condition
      A56-34 (IG1) - Body ground Ignition switch ON 11 to 14 V
