Parts Information

NOTE:
To ensure parts are obtained as soon as possible, order them from GM Service Parts Operations (GMSPO) on a C.I.O. order, with NO special instruction code, but order on an advise code (2).




For the Ninety-Eight, order new PROM based on old PROM, Code or Old Scan I.D. Order quantity based on Estimated Usage column and dealer listing.

NOTE: If all three PROMs for the NINETY-EIGHT model are not in stock, check the old PROM Scan I.D. using a scan tool before starting the SERVICE PROCEDURE.
