Need some advice please.

I have a Renault Grand Scenic 2011 with no power to the cigarette lighter, electronic parking brake switch, or centre console. Receiving "check transmission" fault.

Swapped body control module and ECU etc to make sure they're ok. Still no power to above.

Personal thoughts: bad ground somewhere.

Can anybody advise on wiring for ground points for these systems or if you've had the same problem yourself, did you find the solution?

Thanks in advance.

We get a bit confused on here ( Well I do )
You changed and fitted a full ECU kit, or .
You Coded Another ECU and UCH ( what you are calling a BCM ) In..

Why were these tried.. ????
TO cure Injection Issue, or?

You need to fill your garage in,. As we have no idea what engine Gearbox Type, Petrol Diesel LPG

It's a Renault Grand Scenic 1.5 dci automatic.

We changed and fitted a full ECU kit as there was no communication with the old one.

There are no injection issues.

Sorry Transmission..
Has the UCH/BCM been told what Gearbox type is fitted?

Think you need to get into UCH, and check what gearbox type is fitted..

The Donor could be showing manual, and this wants changing ...
Also while in there check its set for electric parking brake..
