Abnormal Learning of Stroke Sensor Zero Point (Test Mode DTC)

DTC

C1392

Zero Point Calibration of Stroke Sensor undone

DESCRIPTION

The brake pedal stroke sensor assembly sends a signal about the pedal stroke to the skid control ECU (brake booster with master cylinder assembly).

DTC C1346 will be cleared when the brake pedal stroke sensor assembly sends a brake pedal stroke sensor assembly signal or when Test Mode ends. DTC C1346 is output only in Test Mode.

DTC No.
