DTC Code DTC Name
C1417 High Power Supply Voltage Malfunction

DESCRIPTION

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

This DTC is stored when the +BS terminal voltage deviates due to a malfunction in a power supply or charging system circuit such as the battery or alternator circuit, etc.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1417 High Power Supply Voltage Malfunction +BS terminal voltage is more than 16.5 V for 1 second or more.

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

    2. Disconnect the A120 skid control ECU (brake actuator assembly) connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      A120-25 (+BS) - Body ground Always 11 to 14 V
      A120-25 (+BS) - A120-38 (GND1) Always 11 to 14 V
      A120-28 (IG1) - Body ground Ignition switch ON 11 to 14 V
      A120-28 (IG1) - A120-38 (GND1) Ignition switch ON 11 to 14 V
