Read evidence and context

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.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

They are run on the most bus fibre optical system and have an internal code number which it remembers - it doesnt matter if you disconnect the battery, the coding will remain.

I've gone through the paperwork and noticed that there is no code card for the PCM2 unit to enter if the power supply is interupted when changing the battery etc.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

I have just changed over from a 2000 boxster with PCM1 to a 2003 996 c2 with PCM 2 . I've gone through the paperwork and noticed that there is no code card for the PCM2 unit to enter if the power supply is interupted when changing the battery etc. I had one with the PCM1 unit on the boxster, does anyone know if the PCM2 has feature. I can't find any mention of it in the manual. Migration info. Legacy thread was 21721

POST 2Original post

PCM 2 as well as CDR23 do not come with codes any more. They are run on the most bus fibre optical system and have an internal code number which it remembers - it doesnt matter if you disconnect the battery, the coding will remain. Migration info. Legacy thread was 22014
