Re: Additive ECU no communication
Personally, I suspect it is a multiplexed pump. In case it is of any use here is the anomalous diagram showing separate additive ECU for a multiplexed pump:
1282: fuel additive ECU / (Not reliable)
1283: fuel additive pump
1320 is the engine ECU
1282: fuel additive ECU / (Not reliable)
1283: fuel additive pump
1320 is the engine ECU

I still have not got to the bottom of this. Is there any chance you can find a wiring diagram that shows the additive pump without the additive ECU????
Thanks.

Re: Additive ECU no communication
No, because it is still coming up for this vehicle separately Phil. The only difference is multiplexed additive pump or not.
