2004 Honda Civic Q&A
2004 Honda Civic Question: Article says there is a software update for PCM in a 2004 Honda Civic.
I cant get rid of engine light with O2 sensor codes. Replaced both sensors with Honda parts and still get engine light. Read article that says there is a software update for the PCM. Honda dealer says he never heard of it and could not find any info on that idea. Do I just get a different PCM from a salvage yard and see if that fixes it or can you verify a software update for this problem????? - screwcrew
At times a car line will release what is called a Technical Service Bulletin (T.S.B.) to dealerships that service advisor, service managers, and technician don't know about since there are so many. So there may be a T.S.B. regaurding the problem. - gmc4me
post your complete vin# and I can check.Honda techs DO have access to checking VIN status. If you post SPECIFIC DTC I can also check for any service bulletins related to it.....Curious Question , what was the source of the article you read? The other reason they might have said there is no update , is that your car might already have the 'updated' version or the tool they use for updates did not have the appropriate software version itself, which in turn , would say that your vehicle did not have an update available. - ziptie12
