First, I’ve searched a couple days with no luck, what I’m wondering if anyone here that actually works at a dealership can help, or anyone that has fixed this issue.
I installed the full bypass kit from Hewitt back in April. Installed easily, cleared the codes, has ran great since then. Until Wednesday when he had our first real cold day. Wife started off taking our son to school and noticed in the parking lot the CEL came on, did the normal shut down of TRAC and so on. Went and got it checked and it’s only the P2445 code. Emailed back and forth it Hewitt support and learn this is a know “glitch” in the ECM, due to it not throwing the code on start up. There was supposed to be a calibration file issued a few years back that is uploaded to the ECM that corrects the glitch and gets rid of the code. Then Toyota apparently issued a new service bulletin stating the entire system had to be replaced(of course, not recalled like the sequoia and tundra).
If anyone knows what that calibration file number or identifier is so I can tell them when I get to the dealership I’d appreciate it. I already feel like this will be a nightmare because they will tell me it doesn’t exist, blah blah blah, have to replace the whole system, blah blah blah.
Any help would be greatly appreciated, and anyone who has dealt with this same issue if you have any other options or advise I’d appreciate it.
