345 PJW prefix, keeps loosing FLS parameters, as a result, engine ecm error displays on the monitor. What am I missing here?
Engine ecm has lost his parameters u need to replace it
Replace the ecm you mean or parameters? I can use ET configuration tool to input the correct FLS and FTS figures but they are not stored.
Yes replace ecm because they not keep restored
Try flashing the same Part number of engine software file that the ECM already contains. I've seen quite a few cases where ECMs went cranky and were cured with a re-flash. if that doesn't work it's a replacement ECM I'm afraid.
Yes, I've also had a few ECMs lose their FLS or FTS. Fortunately because the setting goes 'blank' you don't need a factory PW to reprogram it. Unfortunately if it happens again the cure is a new ECM. Interesting you're working on a 345. The last two I've had have been on medium/large HEXs. A 345 and a 365.
That's always a good point to remember because you only get one "attempt" to install FLS & FTS in a blank ECM without requiring Factory Passwords.
Thank you gentlemen. Your input it greatly appreciated.
