Code B0988 Description
When the system is operating and can detect the lane markings, the VDAAW module will request via serial data communications that the Instrument Panel Cluster (IPC) illuminate the green lane departure ready-to-assist indicator. If the VDAAW module detects that the vehicle has crosses a lane marking without the turn signal being used, the module will request that the IPC flash the yellow lane departure warning indicator. An audible warning will also sound three times when the yellow IPC indicator is flashing.
