EDC15C2 - P0380 - after switching ECU

[Azzx]

Hey

I have switched FAP ecu to non FAP ecu in Citroen C5
(swapped 5p08) car runs fine but..

On the original ECU (with FAP, RHS) I have no DTCs
regarding glow plugs (P0380).

On the new ECU (RHZ engine) I have DTC P0380
about preheater or glow plugs.
One DTC P0380 - short to ground or circuit break,
Second DTC P0380 - permanent plus on the relay on it.

One the new ecu pre heater (glow plugs) relay test
from Lexia works OK, glow plugs are running and
everything seems fine besides the DTC.

Anyone of you know how to solve it?

Why don't You remove FAP from RHS ECU?

I did got two ECU's but in the car airdosers, electrovalves except turbo has been removed so it throws error according to them except but P0380 did not appears.
The air inlet from hot/cold reduced to the cold only.

Glow plugs are OK, voltage is delivered to them, from Lexia the preheater relay test - OK.
There appears only DTC P0380 but glowplugs works like they supposed too - strange.

PS. Witam ;)
