i put a code reader on my punto and its showing the codes 1600 and 1602 does anyone know what these code are ? or how i can find out ? thanks
 
P1600 - Immobilizer system malfunction Probable cause:-

Incorrect / damaged key, incorrectly programmed, wiring, poor connection, immobilizer read coil.


U1602 - CAN Data Bus - communication error probable cause:-

Wiring, poor connection.

I'd say the 1600 was brought on by 1602.
 
I have a similar problem with a friend's Punto 1.2 Auto. The eml is coming on while the car is driven and one of the 2 codes in the system is 1602. My friend has told me that the ECU near the top of the engine has recently been replaced with a new unit. Would this have anything to do with the light coming on? Does anyone know if the ECU needs to be coded to the car?
