Presence of Key parameter collapsing from Yes to No when starting

Unread post by Stanoyugi »

Hello,
My 407 2.0 Hdi does not start due to the Presence of Key parameter collapsing from Yes to No the moment you try to crank. I have checked the immo diagram, everything seems fine.
I have relearned the key code and nothing seems to work.
I have installed another complete set of BSI, ECU, Key but situation remains the same. But the Key parameter keeps on collapsing.
Any help on what to check from forum members.
