Guys,
i drove down to baltimore yesterday in my 997. everything worked as normal.
I turn the car on today, and i got this error.

any ideas on how to fix it ?

it literally just happened overnight.
the only thing im thinking is that the humidity might have played a factor ???
the radio displays the station and the name of the aritst/track but there is no sound.
Sat radio does not work. CDC and Ipod arent working either...

 

Intermediate communication failure of a devise in the MOST loop is the likely culprit. Do you have a 3rd party product in the loop? Tooki, Mo-Bridge, etc?

Agree with Walt.

You have a disruption in MOST.

 

the car has an ipod wire coming from the glovebox. it's always worked absolutely fine. i havent touched anything.

ive been driving the car for 3 weeks now and this just happened out of nowhere.

 

disconnected the battery for 30 seconds. now its back to normal.
bizzarre.

 

Which aftermarket interface do you have? Most have a reset button that should be accessible, and save you the trouble of disconnecting the battery.

 

i have no clue. theres just one cable thats in the glovebox and goes to the back of the pcm unit.
pardon my ignorance, but what exactly is the "interface" ?? i access it by pushing the cdc button.

 

Post a picture of the cable.

That doesn't look like the cable that comes with either the Dension, Nav-TV, or MoBridge.

Not sure if you have a reset button.

 

My dennison does the exact same thing, just tun it off, lock and unlock with the key out and restart, back to normal. Btw, my dennison has that same pos cable.

 

I have XM on mine... It happens to me every so often...a couple of times a year. The first time I disconnected the battery as well and all was fine afterwards.

The second time it happened I had to stop by the gas station and get gas. When I shut the car off and restarted it after putting gas, everything was fine. Every time it has happened to me after that, I waited until I had to stop or turn the car off. Then the problem would go away. Weird...I am glad it only happens 2-3 times a year though.

 

I think if you press 148 all at the same time it will re-boot the PCM.
