Redundant brake pedal sensor short circuit to battery.
• Check wiring (to brake pedal sensor) • Check connectors (to brake pedal sensor) • Check brake pedal sensor • Measure the sensor voltage between signal and ground • Check brake pedal mechanism
What you'll see
Continuous brake light. Problem activating exhaust brake. Brake pedal information sent on the CAN-bus is labeled with an error indicator. Cruise control is disabled Adaptive Cruise control is disabled Collision Mitigation (warning and/or brake assist) will be deactivated.
System reaction
No system-reaction text recorded.
Diagnostic depth
Impermissible signal from the brake pedal redundant sensor. The sensor voltage level is too high. The brake sensor is short circuit to supply voltage.
• Defect wiring - short circuit between brake pedal signal (pin C12) and supply voltage (+5V or +24 V) - open-circuit on brake (redundant) ground connector C21. • Defect connectors • Defect brake pedal sensor (potentiometer) • Mechanically defect brake pedal mechanism (causing brake pedal sensor to reach an impermissible position)
