Renault Espace IV 3.5V6 Hitachi Hi-ewr20 Immo

[kierownikszatni]

Hi,

i have problem with Renault Espace IV 3.5 V6. The car won't start after discharge battery. Immo light is on. Steering lock is ok, connection between ECU and UCH too, I can turn ignition on but engine doesn't start. In ecu there is immo problem. Power feeds, Gnd etc are ok. In the eprom the place where should be VIN is empty. Probably there is problem withe eeprom content. Does anyone have eprom for this ecu, or can repair mine? Or maybe the problem is elsewhere? I don't have idea what to do... In the country where I live this car with this engine ( 3.5 V6 from nissan) is very rare so I don't have experience.

In attachment eprom read from my ecu and photos of ecu.

Thanks in advance.

What is a VIN? Do you read UCH95160?

[kierownikszatni]

code stored again, what you have a problem?

Code stored again but vin is empty. Should i write vin manualy or via clip? Immo light is on, engine doesnt start. In ecu immo fault code. Starter works but engine doesn't start. No fault codes in other units.

No, I can't do it. The only person I know who can help with this is the user @Le-Mans. Ask him.
