CEL 1412

[Croc999]

Car - Euro 2007 S2000.

since FPM 1.8.2 i have CEL 1412 which is not documented in US Honda service manual.
according to UK s2ki wizards it's related to air pump relay.
currently air pump doesn't work.

this CEL started immidiately after reflash new tune with FPM 1.1.8.2.
it continued with following FPM releases including 1.1.8.5.

tune file is attached.

Thx, Gennady

2 other Euro s2000 owners reported the same problem:

hello,

i recently upgraded my FPM version from 1.1.7.4 to 1.1.8.5 and uploaded my final calibration to the car which is a 2006 EDM S2000.

i immediately received a CEL as P1412. i guess this is related with secondary air injection system. i have never received such a CEL during my uploads with FPM 1.1.7.4.

does Hondata think that it is related with the latest version of FPM?

i am using a test pipe. i think it will be very valuable to have secondary air injection delete feature in FlashPro.

so it must be caused by the FPM.
since the problem started from the FPM version which intriduced boost control - it might be somehow related.

looking at this Honda's guide it looks like ECU pin A31 controls the system:

how?
is there a Euro S2000 version of FPM? where do we download it?
nothing has been reported by Hondata at the web site or forum up to now???
there are many Euro S owners waiting for the next release of FPM for the bug resolution?

[Croc999]

i think "terryl" was asking whether this was solved.

i see ver 1.1.8.5 at Hondata's website - so i'm still waiting.

sorry, i misunderstood terryl's statement because of waiting for months :):):)
i bought a ScanGaugeII device to reset CEL EVERY time i drive. i am improving about CEL1412 bug day by day!
hondata support previously stated that bug resolution is done. i hope next version will be released before Honda announces the next version of S2000.

Hello Hondata,

don't mean to irritate - but perhaps you could do a minor release just ot fix our issue?

thx,

Sorry, but to release the software there are other changes which must be completed and tested - this is why we usually don't give release dates. We should be able to make a beta build shortly.
