C1417








BRAKE CONTROL: ANTI-LOCK BRAKE SYSTEM (for Hatchback): C1417: High Power Supply Voltage Malfunction

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 generator circuit, etc.
The DTC is cancelled when the IG1 terminal voltage returns to normal.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK BATTERY
(a) Check the battery voltage.
Standard voltage:
11 to 14 V
NG -- CHECK OR REPLACE CHARGING SYSTEM OR BATTERY
OK -- Continue to next step.
2. INSPECT SKID CONTROL ECU (IG1 TERMINAL)




(a) Disconnect the skid control ECU connector.
(b) Inspect the connector case and the terminal for deformation and corrosion.
OK:
No deformation or corrosion.
(c) Turn the ignition switch to ON.
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:






NG -- CHECK POWER SOURCE CIRCUIT (IG1 CIRCUIT)
OK -- Continue to next step.
3. RECONFIRM DTC
(a) Reconnect the skid control ECU connector.
(b) Clear the DTC ABS (Antilock Brake System) (for Hatchback).
(c) Start the engine.
(d) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(e) Check if the same DTC is recorded ABS (Antilock Brake System) (for Hatchback).

Result





HINT: If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step Problem Symptoms Table.

B -- REPLACE BRAKE ACTUATOR ASSEMBLY
A -- CHECK FOR INTERMITTENT PROBLEMS (SYMPTOM SIMULATION)
