R32 Nissan Skyline GT-R : ATTESA Code 1 , Code 2, Code 3, and Code 4

Troubleshooting ATTESA codes 1,2,3,4.  These are all wheel speed sensor codes.

The first thing to check on any code 1, 2, 3, or 4 on a Nissan Skyline is to have a look at the sensors, wiring, and the pickup rings.   Since the sensors are magnetic, they have a tendency to pick up small pieces of metal, and that can affect the readings.   So get some cleaner and make sure each pickup and wheel is good.

Then make sure all the connectors, and wires are intact. Reset ATTESA ECU.   Test and see if you are still getting same codes.
