ECM AND PCM VIN WRITING DURING
CONTROL MODULE REPLACEMENT
SUBJECT
:
This TSB supersedes TSB# 04-36-019 to update the service procedure.
Description: This bulletin provides the procedure to write the Vehicle Identification Number (VIN) during
the replacement of the Engine Control Module (ECM) or Powertrain Control Module (PCM). Once the
VIN has been programmed to the ECM/PCM, it cannot be removed or overwritten.

All vehicles are shipped with the VIN pre-programmed into the ECM/PCM. If either the ECM/PCM
needs to be replaced, the VIN must be programmed to the new module.

A new ECM/PCM requires that this function be performed following installation. Failure to perform
this function will result in a check engine light with DTC P0630 (VIN not programmed or
mismatch).
Applicable Vehicles: All 2005 or later model year Hyundai vehicles
!
WARNING
Input of incorrect VIN during the writing procedure requiring the purchase of a new ECM/PCM is
non warrantable.
!
CAUTION
Do not exchange an ECM/PCM from another vehicle as a permanent repair. If the module has to
be replaced, a new service replacement control module must be used, and the VIN must be
programmed into the new control module.
