Auyo manual gearbox stuck in neutrol

[JOE+TECH]

Hi need some help got Citroen Belingo B9 2016 Vin VF7**************[VIN obfuscated, can be read by forum staff]
I think it is a Manual /pilot auto gearbox
Stuck in neutrol will not go into any gear not drive, engine starts ok
Would like if possible wiring diagram to cover this gearbox + power supplies/earths and the controls
Thanks JOE+TECH

You really need to get it connected to a good diagnostic machine to read the fault codes and check the live data for anomalies.

As mentioned by my colleague above, a wiring diagram is not going to help at this stage. Piloted manual gearboxes can have a plethora of faults associated with the system. The gearbox / clutch actuator system has entered a refuge mode due to a specific problem.

This can be caused by a multitude of issues, a few being: a new clutch / flywheel required, the actuator itself, programming of the system for the gearbox grid etc., hence why we would need the fault codes specifically.

Thanks for quick reply, main problem no communication with auto gearbox
Engine starts but reports no comms with auto gearbox ,gearbox will not engage gear if it cant see what engine is doing
Would appecate wiring diagram to check can wires also power and earths for communication purpose
Thanks Joe

I don't have a wiring diagram for your car, but prime contenders for no communication faults would be a blown fuse or corrosion in an ECU connector.

Here is a wiring diagram for a piloted gearbox on a 508, which should give you an idea of the ECU pin-outs for checking voltages.

1320 is the engine ECU and 1660 the transmission ECU

Gearbox fixed,thanks for your help ( great forum knowledge )
It was the wiring diagram checking circuits that got to the fault
1 Powers ok
2 earths ok
3 when disconnecting harness plug an gearbox I noticed some green corrosion, Can wires not connecting to gearbox
So not able to receive engine dat,a so gearbox not engaging any gear
Cleared faults, road test gearbox workinfor yourg also paddle shift gearshift
Thanks again for your help JOE-TECH
