Removal And Installation
NOTE:
If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to determine if alignment of the PROXI configuration data into the new ECU is needed. If PROXI alignment is needed, follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under the Body Control Module (BCM) Miscellaneous Functions menu.
The Electronic Shift Module (ESM) is integrated into the transmission shifter. To replace the ESM the transmission shifter assembly must be replaced (Refer to the appropriate diagnostic information - 948TE/SHIFTER, Floor Console/Removal and Installation).
