02 1.4 Starting problems- what do these codes mean - Dodge49
This is my brother-in-law's car so I hope I get this right. Twice his car has failed to start with the problem being the immobiliser (light staying on). On both occasions he left the car overnight and managed to start it the next day after about 20 minutes. Since then the engine malfunction light has been coming on and off for different lengths of time.

Yesterday he took it to a garage and got the following codes
u0001 high speed can communication bus u2510 invalid security data recieved from ecu.
Ford had the car for 2 days but could not find or fix the fault.
The car seems to be running okay once started.
Any ideas would be appreciated.

Thanks
