We encounter a problem after doing a PM of the G7167A MLS, when doing auto referencing after changing needle seat and seals, it gives and unknown module error 25089. As the MLS require realignment, it won’t let the needle be in service mode. I use lab advisor try to move the needle in the ‘Instrument control’ page, it gives another error 25146 means the value of the needle is missing, I cleared the auto reference value in lab advisor, restarted with no luck. I tried a cold start also with no luck, and I reinstalled the same firmware and it still no luck.
I unclick the needle take the needle out and unscrew and screw it back the wash port in case the wash port isn't aligned. but now I couldn't put the needle back. I restart the MLS and it reinitialize ok as usual but ask for realignment otherwise it always in not ready mode. Once do autoreferencing in instant pilot controller and the same unknow module error 25089 occur.
thanks in Advance
