Code B1474 Cadillac Description

The left front interior door handle, left front exterior door handle, right front interior door handle and right front exterior door handle switch signal circuits provide inputs to the Driver Door Module (DDM) or Passenger Door Module (PDM) when an interior or exterior door handle switch is activated. These inputs allow the door module to detect a door open request. The door modules provide voltage to the door handle switches. If the door module detects that a ground is applied for greater than 180 seconds, a DTC is set and the door module will ignore the door handle switch input. The Diagnostic Trouble Code (DTC) sets when the DDM or PDM detects a short to ground on an interior or exterior door handle switch signal circuit.
