Code C116A Lincoln Description
When the brake pedal is pressed, the stop lamp switch closes and a voltage is sent to the Powertrain Control Module (PCM). The PCM then sends a message over the High-Speed Controller Area Network (HS-CAN) to the ABS module indicating that the brake pedal has been pressed. DTCs set in the ignition cycle can only be cleared by cycling the ignition off and on once the fault has been corrected.
This DTC sets in every ignition cycle if during normal operation, the stop lamp switch message does not match the HCU transducer, both signals have to agree about whether the brakes are being applied or not.
