SEA DOO GS / GTS / GTI / GTX / GTX RFI / GTX DI / RX / RX DI / XP TROUBLESHOOTING CHART
The following is provided to help in diagnosing the probable source of troubles. It is a guideline and should not be assumed to have all causes for all problems.
NOTE: On RFI and DI models, always check for fault codes recorded in the MPEM first using the VCK (vehicle communication kit (P/N 529 035 676). The MPEM programmer (P/N 529 035 718) can be used on the RFI models. If a fault code is detected, service the fault code and recheck operating conditions. Refer to Diagnostic Procedures in ENGINE MANAGEMENT section.
