# Service bulletin TT 93\-12\-01

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

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.
