C1417

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1417: High Power Supply Voltage Malfunction
C1417 - High Power Supply Voltage Malfunction

DESCRIPTION

If a malfunction is detected in the power supply circuit, the skid control ECU (housed in the 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 cleared when the IG1 terminal voltage returns to normal.





WIRING DIAGRAM

Refer to DTC C1241 C1241.

INSPECTION PROCEDURE

NOTICE:
* When replacing the brake actuator assembly, perform calibration Programming and Relearning.
* Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1. INSPECT BATTERY

(a) Check the battery voltage.

Standard voltage:

11 to 14 V

NG -- CHECK OR REPLACE CHARGING SYSTEM OR BATTERY Testing and Inspection
OK -- Continue to next step.

2. CHECK TERMINAL VOLTAGE (IG1) C1241

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (IG1 CIRCUIT)
OK -- Continue to next step.

3. RECONFIRM DTC

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(b) Turn the ignition switch off.

(c) Check if the same DTC is output Reading and Clearing Diagnostic Trouble Codes.
