HCH Computer updates & TSBs
Check engine came on last week (at about 65,000 miles), along with the IMA light. IMA light went out, but check engine stayed on. Dealer ran codes to determine the cause (and charged me $80 for the honor). Codes that came back were P1600 and P1440. They reported that both of these have to do with IMA system malfunction. Checked IMA and all seems fine. Interesting.
They "reset the computer" to get rid of the check engine light and reported that they were upgrading the computer with 3 new updates. I didn't understand what they were talking about, so asked for more details. All my service advisor shared was that there were 3 separate TSB updates for the computer that they were loading after they reset.
It peaked my interest, so I started digging around on the internet and found a list of TSBs for the HCH, including some that seem to indicate computer updates, problem codes, and ODB II readings. I can't seem to find a site that will show me the full text of these without paying to register.
1) Thought you all might be interested...
2) If anyone has further insight or knows where I can see these in full, I'd appreciate it.
For now, I'm hoping the engine light doesn't come back on!
