Alpine OBD system connector

[dtimme]

Is there an adapter available for the Doetsch connector from the 2002 Alpine Motorhome onboard diagnostic system connection to a OBDII diagnostic system?

Hello & Welcome to IRV2 and the Alpine Forum:

Cummings ECM cannot be read by a standard OBDII diagnostic tool. If a shop works on cars and small trucks as well as large commercial vehicles they may have one tool with the ability to diagnosis both types of vehicles. The costs are very high for the yearly updates for foreign and domestic vehicles as well for large commercial vehicles.

From what I have seen most repair facilities have diagnostic tools for cars and small trucks or for large commercial vehicles but not both.

Thank you for your response. That makes the most sense for an explanation of the things I have found in my searches.
