Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Lately I've been trying to ID an intermittent problem which seems to slowly be getting worse. The situation: 2002 Boxster 2.7 with a professionally installed SiriusXM converter, and a Pioneer radio from Crutchfield which I installed. The symptoms: The car runs great. Normally the car turns on when I turn the key, and the satellite radio and Pioneer radio come right up. The alarm will chirp when I lock the car (even though I thought that I had deactivated that.) Occasionally when I try to start the car the Sirius unit and the radio will be dead, and the car won't start. I'd noticed a clicking sound from the radio console which I've identified as the SiriusXM FMDA25 FM Direct Adaptor. It's a small black box which switches between the AM/FM Antenna and the Satellite Radio FM out plug. Using my Durametric OBD reader, I also noticed an "Alarm I48 - Fault 25 "Status lead, signal converter, short circuit to B+". When it happens, it can happen multiple times. I haven't found much of an explanation for this fault, but I suspect that the "B+" refers to Battery-plus or +12V (as opposed to a short to ground). If there is no clicking sound, then the tunes come up fine and the car starts. The relays only seem to cost ~$15-$20, so I'm going to swap it out and see what happens. Anyone else ever run into this?

POST 2 / ORIGINAL POSTEROriginal post

Just logging the solution. I replaced the relay, and the new one started clicking even faster when the car wouldn't start. So I pulled out the entire SiriusXM system, and now the car and alarm work fine.

This is a source reference. Confirm exact model applicability in the original material.
