Drive Motor Position Not Learned, Fault P0C4E/P0C4E00

VOLKSWAGEN · 2012-10-26

Tech Tips (Drive Motor Position Not Learned, Fault P0C4E): The drive motor position will need to be relearned after DTC codes have been cleared, battery has been disconnected or a recharge of the 12 volt battery has taken place. The VAS PC and ODIS programs will have the technician perform this task at the end of diagnostics and module fault code erasing. This can also be accomplished without the need for a scan tool if this recalibration procedure is followed after a battery disconnect, recharging of a low 12V battery or code clearing with a generic scan tool. This document informs how the vehicle learns the Drive Motor Position.
