Hello,

I have a a 2015 Subaru Impreza, Chassis #GP2-033395 without Immobilizer yet there is an Immo Light Flashing in the Cluster and the cannot start.

There is No Immo Ring and No Connector for it either. Immo Ligjt comes on when the key is inserted. Car will Crank till the light comes on then cranking stops.

Engine ECU has "DY" Label with 93C56 Eeprom, BIU Body Control has "GA" Label with 24C01 Eeprom and Cluster has 93C76 Eeprom.

Took files from another Similar car but boxes had different labels and BUI had 24C02.

Tried to align by OBD with Launch, G-Scan, AVDI Diagnostic Tools without success. Dealer quit on this car.

Looking forward to your reply.

Actually your file does not have keys, but can you tell us what fault code you have in motor ecu?

Hello,
Thank you for your attention. I will scan the car and send ECU error CODES tomorrow. This car has no immo yet cluster immo led Illuminates and cranking stops.
Local techs claim to see this often yet their fixes do not work on this car.
I have BIU, ECU and Cluster Dump for what it's worth.

I will analyze your case friend
But I only see in your post the dump of the integrated unit. Please post the file of dashboard, integrated unit or BCM and motor ecu.
I will analyze and give you a solution soon.
