Code B356A 2014 Chevrolet Silverado Description
When the Frontview Camera module is operating and can detect the lane markings, the Frontview Camera module will request via serial data communications that the instrument panel cluster illuminate the green lane departure ready–to–assist indicator. If the Frontview Camera module detects that the vehicle has crossed a lane marking without the turn signal being used, the module will request that the instrument cluster flash the yellow lane departure warning indicator. An audible warning may also sound three times, or the haptic seat (if equipped) may pulse when the yellow Instrument Cluster indicator is flashing. The driver can select between audible or haptic alerts in the vehicle personalization menu. The Diagnostic Trouble Code (DTC) will be set when the Active Safety Control Module has detected a short to ground, short to voltage, or an open/high resistance for more than 10 s.
