hey guys im new on the forum, have a 650H that is very slow on the right side for the first few minutes after it has sat over night, problem goes away after you travel forward & back for 3-6 minutes & then operates normally after that. i gave the codes to a service manager & he said they all have to do with calibrating so it prolly needs to be calibrated. But that makes no sense to me since it goes away in a short while. the codes are : F373 F321 F375 F324 3K3 THANKS!
Since you are seeing code 321 and 324 do not do an immediate calibration. If the last digit of the service code number is (0,2,3, or 5) an open circuit, shorted circuit or no feed back is indicated. Reference the service codes in group 9015-15 transmission circuit. If the last digit of the service code is (1 or 4), a calibration error or circuit failure has been sensed. Access main menu and select the DIAG in the transmission controller. Compare the calibrated values to real time values. If the valves don't match then you can recalibrate. If the service code it 311, 314, 321, or 324 is being displayed, reference the service codes prior to any calibration. It sounds long and draw out but it really isn't. Hopefully this will help.
