Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I've just tried disconnecting the battery, to see if it 'resets' it but it didn't work and it's still frozen, and I can't scroll thro' temp / MPG / range / oil level etc.

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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Has anyone ever had a problem with their trip computer on a 996..? Driving yesterday, I noticed the green cruise light activate itself which I turned off. When I got home I noticed the trip computer had 'frozen' on range and the control stalk did nothing..? I've just tried disconnecting the battery, to see if it 'resets' it but it didn't work and it's still frozen, and I can't scroll thro' temp / MPG / range / oil level etc. Is there a reset button anywhere..? or a hard reboot fix which generally works on most computers..! I've no idea if its relevant, but the battery tray was under water so I cleared the 4 drain holes while I was in there.

POST 2Original post

You can try rebooting the PCM, just press all together 2,4 and 8 on the number pad. Cannot remember if you have to do this when it is turned off and turn it on when you are depressing the keys or if it will just work when on. Give it a go and let us know how you get on. Hope it solves the error for you.

POST 3 / ORIGINAL POSTEROriginal post

Ah, mines had a PCM swap out, so it's got a Kenwood head unit/Nav that works, with Blue teeth and Ipodery.. so that possible fix is out of reach. It has never missed a beat before now, I'm just wondering if the damp has got into something. Edited by RatBoy M3CSL on Thursday 2nd January 17:59
