Read and clear diagnostic codes for Volvo Penta marine.

Without diagnostic tool

[@WhiteKnuckleRacingJD]

I have a 2002 Volvo penta 5.7 GXi- C. Where can I find the procedure to check the DTC’s without a scan tool for that motor? Google has not been very helpful.

[@stevehez]

Should be the same port. My engine is around 1996-2000.
