Welcome to just I'm here to help you and your 100% satisfaction is my goal.

This can be caused by a number of things checked the connectors at the ABS unit and at the transmission make sure they are clean and all tight with no damaged conductors or terminals Then clear these trouble codes and test drive the vehicle tell me which trouble code occurs first this could be a problem with the solenoid in the transmission or it could be a problem with the front brake solenoid

I did it at Infinity Dealership. They exchange the transmission fluid and check possible things, clear up the "check engine" light. Its come back after 1 min , when I was at the 300 meters from Dealership after "repair" . Now they recommend me "reprogramm" the infinity main unit. But my feeling , that front brake solenoid doing "wrong" couse I can not start moving car quick. "something" holding it. Two codes show up. But first one - about transmittion. Another thing - when I connect my camcorder to my car, its do not work with video. SOund only. Video "tell me" that car need to be stopped first and after that video will be resumed. BUT!! My car was at the parking. ... so .. car "thinking" wrong .May be I'll go there again next week to see what happend. But the same issue - happend in MANY infinities car... And others as well ...... Some cars was fixed by doing "something" with front brake area... But that exapmle was to shorty (online ) the owner "told " that it was quick fix in front brake area...

Yes if you're going back to the dealer I would have them checked to see if the problem with the front brake solenoid valve , they may need to replace the modulator unit and that can get are fairly costly the units run about $900 And it takes about 3 hours to replace

I'll go monday to the dealer. If they do a n y from your advise , I'll accept it. I'll tell them about MODULATOR unit replacement and connectors at ABC unit
