These are Canadian DTCs diagnostic trouble codes. This codes mean a lack of connumication. This are different than American OBII codes.Hope this helps try gooling Canadian Troule Code and writing down the U codes. I hope this helps you. Please vote if you find this helpful.

The U1000 and U1001 mean that there is no communication between the engine control unit and another control units that are part of the CAN system (Controller Area Network) or that at some point there was no communication. Before do any repairs with the U1000 and U1001 codes, the factory recommend repairing any other problems in the car.

I have an engine code u1000 for my 2005 nissan altima. whats that mean?


basically that is a communication code between one or more computers

you need a dealer scan tool or something similar like the $8000 snap-on scanner to verify which computers are suspect and a DVOM to measure voltage on the communication circuits between the suspect computers

long story short.... this is a job for a select few technicians.... your best bet, depending on where you live.... is the dealer
