DTC 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 brake control system operation.
This DTC is stored when the IG1 terminal voltage drops below the threshold due to a malfunction in the power supply or charging circuit, such as the battery or generator circuit, etc.
The DTC is cleared when the IG1 terminal voltage returns to normal.

DTC Code
DTC Detection Condition
Trouble Area
C1417
The IG1 terminal voltage is 17.4 V or higher for 0.8 seconds or more.
  1. ECU-IG NO. 2 fuse
  2. Battery
  3. Charging system
  4. Power source circuit
  5. Internal power supply circuit of skid control ECU (Brake actuator assembly)

Refer to DTC C1241 (Toyota Fortuner RM000000XW60C1X.html).

INSPECTION PROCEDURE

NOTICE:
  1. After replacing the brake actuator assembly, perform calibration (Toyota Fortuner RM000000XHR06WX.html).
  2. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
  3. Before disconnecting the connector, make sure that there are no problems with the connection.
  4. After disconnecting the connector, make sure that the connector case and terminals are not deformed or corroded.
1.CHECK TERMINAL VOLTAGE (IG1 TERMINAL)

  1. Turn the ignition switch off.

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