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 master cylinder solenoid) stores this DTC and the fail-safe function prohibits ABS/VSC/TRAC 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.

INSPECTION PROCEDURE

NOTICE:
When replacing the master cylinder solenoid, perform calibration Programming and Relearning.

PROCEDURE

1. CHECK TERMINAL VOLTAGE (IG1)

(a) Disconnect the A7 skid control ECU connector.

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





Standard Voltage:

NG -- GO TO CHARGING SYSTEM (ON-VEHICLE INSPECTION) Testing and Inspection
OK -- Continue to next step.

2. RECONFIRM DTC

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

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

Result





B -- REPLACE MASTER CYLINDER SOLENOID Disassembly

A -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting
