Morning Everyone
I need the help or the wiring diagram for the Hybrid Coolant Pumps on a 2020 3008 1.6 Hybrid
My Chassis number is VF3**************[VIN obfuscated, can be read by forum staff]
The Problem:
My hybrid system is not kicking in, I'm getting the following errors amongst others:
P0CE9 Hybrid Drive Train Cooling Circuit Electric Coolant Pump INTERMITTENT
P0C47 Traction Battery Cooling Circuit Electric Coolant Pump INTERMITTENT
P0CEC Hybrid Drive Train Cooling Circuit Electric Coolant Pump INTERMITTENT
P0C4D Traction Battery Cooling Circuit Electric Coolant Pump INTERMITTENT
Ive checked the feeds to the pumps (3 wires per pump)
The Traction pump has 12V Constant, 8V PWM and Ground. So all good.
The Hybrid pump has 0V Constant, 0V PWM, but does have a Ground.
I need help identifying where the 12V and PWM wires connect. I've checked all the fuses in the Engine Fuse box, they are all good. A wiring Diagram would really help. I'm more than willing to pay for the diagram.
Also I've attached a link to a picure of the pumps, they reside in the passenger side (UK car) wheel arch near the radiators.

I have no time to search this morning but you may find a diagram at this site: https://www.automotive-manuals.net/peugeot/ Good Luck 
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!
