Code B2275 Mercury Description
When 1 or more of the following Diagnostic Trouble Code (DTC) is set, the adjustable pedals will enter a jog mode. When the pedals are in jog mode, the memory system recall will not function from either the Remote Keyless Entry (RKE) transmitter or the memory SET switch buttons. When the pedals are actuated using the adjustable pedal switch, the motor will move the pedals for one second in the direction selected regardless of the length of time the button is actually pressed.
If the DSM detects a short to ground on circuit VPP16 (BU/BN) during normal operation or an on-demand self test and without any pedal switch input, DTC B2275 will be set.
