Renault Espace IV X81 not start

[kanzus]

Hi,

I have a trouble starting Renault Espace IV X81 2005 year.
ECU is EDC15C3 bosch 0281011103 eprom 5P08C3.
UCH is Sagem 8200315964 - 28114844 - 8A - AV11.00, EPROM 95160.

Key cards are recognized, engine turn with starter when ignition on, but not start.

Immo light dashboard remain on (not blink).

I can see UCH on diagnostic but not the ECU (with AVDI diag).

Seems to be UCH block signal to ECU for injection.

Please HELP, could someone send me virgin UCH dump 95160, so I will try to learn keycards.

Thanks.

Do you mean reprogram cards with new blank transponders?
I already learn same keys with AVDI but still not work.

"Immo light dashboard remain on (not blink)" means you don't have communication with engine ecu ... maybe blow fuses ?? maybe engine harness problems ?? If noone of this then is possible your engine ecu to be dead.

I tryed other virgenized ecu, problem remains present.
Fuses and relays ok.
Should I change BCM ? (relay box in engine bay)

Hi All,
Thank you for your help.

I finally reflashed original ecu with flash attached and virgin 5p08c3.
Original flash was corrupted checksum was not good (tested with ECM2001), and second ECU I tryed with was one for Espace III and not for Espace IV.
