4. SERVICE PROGRAMMING SYSTEM (SPS)

4.1 GENERAL INFORMATION

On VX Series vehicles equipped with either a GEN III V8 engine or a V6 Non Supercharged Engine, the PCM

does not contain a removable PRO M, it uses an EEPRO M (Flas h Mem ory) which is non rem ovable. The PCM is

programmed from the factory with the proper calibrations for vehicle operation. In the event that the PCM is

replaced, or an updated c alibration is required to c orrect a vehic le's operating condition, the PCM will have to be

programmed with the new calibration. Programming is accomplished through the vehicle DLC using the Tech 2

Service Programming System (SPS) and TIS 2000.

A ser vice r eplacement PCM will not be programmed. DT C P0601 indic ates that the PCM is not pr ogrammed and

DTC P0602 indicates that programming has malfunctioned. For further DTC information and diagnostic
