Thread: Can Link Error

What diagnostic equip are you using? CAN link error can be related to the diagnostic equipment/software not being fully compatable with the TD5 and is a diagnostic equipment error code not a Land Rover code. Some vehicles use a CANbus system the TD5 doesnt so a communication error comes up.
May be your problem.

I have no idea what type of diagnostic equipment their using but as they are a specialized Rover workshop I would imagine they have the correct tool.
Seeing as the car is running fine, I'm not concerned, might be a glitch on their side.
Thanks for the input.

A CAN error is a communications fault between the ECU and whatever may be faulty, it comes up a lot if there has been faults recorded, oil in the injector harness and MAF faults usually trigger it on most occasions.

TD5s do have CAN BUS as well.

OK I stand corrected. I just Googled canbus and now know less than I did before. I have had similar errors come up on diagnostic equipment used on heavy earthmoving equipment and it is usually a communication problem. The software i am used to will identify if there is a communication problem, either input or output, between a sensor and a controller and log a seperate error. I have had later versions of software bring a similar error up on older machines because it is searching for a CAN system that is not there. Bring back the days when there was no monitoring, we could reduce breakdowns by 90%, but the other 10% would probably be terminal.

Soooooooooooooooooo?
As I have had the injector loom replaced as it had oil in it, could there be still some oil in the ecu side of the plug causing this code.
As the car seems to be running fine, should I not worry about and just drive it?
Can Bus?????????
Whats that?
Please excuse my ignorance.
I'm starting to think my Italian motorcycle is not so complex any more
Thanks for the replies.

Are you saying Italians are not complex people, the hand signals most of my Italian friends produce are not simple.

In simple terms a CAN system (Controller area network) is a way for sensors and switches to provide information inputs with a controller and the controller to provide outputs to sensors or other controllers without having complex computers everywhere. It reduces bulky wiring harnesses and such. You can have, say 5 sensors providing inputs, one will say I think I have a problem, another may say I know I have a problem and a third may say I have a problem and it is terminal. The other sensors in the system if related will be saying, nah we're all right. This third fault will take priority and may shut down the engine or drop it back to idle. The second fault may cause a controller to adjust fuel input or similar. All faults should still be logged. Some systems I am used to have a number of digital inputs and outputs from a number of sensors all on one wire which makes faults a little harder to diagnose.

The TD5 is mechanically simple,, its just a diesel after all.

The electronics are amazing though.

A MUCH maligned and under-appreciated piece of LR engineering.
