JD CT-322 Codes

[OldAllis]

My ct322 has these codes displaying; F9H9 F9P8 F9P9 The last time I used it it added a couple repeat codes so I know they are still an issue. I have searched the threads and found conflicting interpretations of one of these codes. I was hoping someone could help me out and fill me in on what potential issues are causing these codes to display. Thanks

F9H9 = Hydraulic output short to ground (boom lock, bucket lock or port lock solenoid circuit) F9P8 = Park Brake output open or shorted to power (Park Brake solenoid circuit) F9P9 = Park Brake output shorted to ground.

I replaced both boom n bucket lock solenoids but clueless what or where port lock solenoid is. there is a solenoid down on side of valve bank thats does seem to do something as it clicks . Is that it? thanks
