Hi I know this is a old post but looking for help on something similar, I have a Nissan U1D2A20LQ with error code F16. Shift lever was playing up, play in lever so I replaced for new unit. Fitted to truck and have same outcome. Nothing I have done has made a difference, It's a multi truck site so have the luxury of swapping bits, I have checked fuses, wiring etc cleaned out multi plugs etc. Changed dash display & had a brand new ecm in stock fitted to truck still no change. Started it up this morning and it went into forward drive then tried reverse then cut out again, no drive
Any help would be appreciated, pretty sure truck was left outside. We've had cold weather and snow recently in the UK so not sure how long it was left in the weather conditions
