Vehicle Dynamics Module (VDM) DTC Index
WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If vehicle dynamics module (VDM) C2131b is disconnected before VDM C2131a, DTCs C1830, C1770, C1790 and C1795 will be set and must be cleared before an accurate list of continuous DTCs can be retrieved.
