DTC C1247/47: Stroke Sensor Malfunction; DTC C1346/71: Stroke Sensor Zero Point Learning Malfunction (Test Mode DTC); DTC C1392/48: Stroke Sensor Zero Point Calibration Undone [08/2013 - ]: Description
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
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 C1346/71 will be cleared when the brake pedal stroke sensor assembly sends a brake pedal stroke sensor assembly signal or when Test Mode ends. DTC C1346/71 is output only in Test Mode.
| DTC No. | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
