Description
Pedal travel sensor reports a nonzero value during second stage.
Potential Impact
System will request Hydraulic Boost Compensation when driver pressed the brake pedal.
Set Condition
The input rod sensor signal shows a positive value that is larger than the specified offset of the sensor during driving situations. This might be due to a sensor condition, mechanical issue in the pedal assembly, or the driver pressing the pedal. The monitoring counts the time in which the input rod sensor signal is higher than a threshold and the acceleration pedal is applied simultaneously while the vehicle is driving. The input rod threshold is higher than the specified sensor offset for reasons of robustness.
Clear Condition
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
