RECONFIRM DTC
DTC C1417 High Power Supply Voltage Malfunction
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU (master cylinder solenoid) stores this DTC and the fail-safe function prohibits ABS/VSC/TRC 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.
This 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. | Charging system
Power source circuit
Internal power supply circuit of the skid control ECU (master cylinder solenoid)
|
WIRING DIAGRAM
Refer to DTC C1241 ().
INSPECTION PROCEDURE
- After replacing the master cylinder solenoid, perform zero point calibration and store the system information ().
| 1.CHECK HARNESS AND CONNECTOR (IG1 TERMINAL) |
Disconnect the skid control ECU (master cylinder solenoid) connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Condition | Specified Condition |
| A24-46 (IG1) - Body ground | Ignition switch ON
(Engine running) | 11 to 14 V |
