DTC C1247: Stroke Sensor; DTC C1346: Abnormal Learning of Stroke Sensor Zero Point (Test Mode DTC); DTC C1392: Zero Point Calibration of Stroke Sensor undone [02/2019 - 12/2021]: 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.
