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 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.
  1. Battery
  2. Charging system
  3. Power source circuit
  4. Internal power supply circuit of the skid control ECU

WIRING DIAGRAM

Refer to DTC C1241 (YARIS_NCP93 RM000000XW60CEX.html).

INSPECTION PROCEDURE

NOTICE:
  1. When replacing the skid control ECU (brake actuator assembly), perform zero point calibration (YARIS_NCP93 RM000000XHR078X.html).
  2. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
1.INSPECT BATTERY

  1. Check the battery voltage.

    Standard voltage:
    11 to 14 V


NG
CHECK OR REPLACE CHARGING SYSTEM OR BATTERY (YARIS_NCP93 RM000001GNJ010X.html)
OK


2.CHECK TERMINAL VOLTAGE (IG1 TERMINAL)

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

  1. Turn the ignition switch to ON.
