DTC 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 alternator circuit, etc.
The DTC is cleared when the IG1 terminal voltage returns to normal.

DTC Code

INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform zero point calibration (COROLLA_ZRE142 RM000000XHR08KX.html).
1.INSPECT ECU-IG NO. 1 FUSE


    Corolla. Zre142 Aze141.Brake Control Dynamic Control Systems.Anti-Lock Brake System. Dtc C1417 High Power Supply Voltage Malfunction

  1. Remove the ECU-IG NO. 1 fuse from the main body ECU (instrument panel junction block).

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    ECU-IG NO. 1 (10 A) fuse
    		Always
    		Below 1 Ω


NG
REPLACE ECU-IG NO. 1 FUSE
OK


2.CHECK BATTERY

  1. Install the ECU-IG NO. 1 fuse.

  1. Check the battery voltage.

    Standard Voltage:
    11 to 14 V

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

  1. Disconnect the skid control ECU connector.

  1. Turn the ignition switch to ON.

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

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    A66-34 (IG1) - Body ground
    		Ignition switch ON
    		11 to 14 V
    HINT:
    If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step (COROLLA_ZRE142 RM000000XHN0DUX.html).
