Thread: Discovery 2 codes

They might just be stored codes after events happened, it may not mean they are current.

Have you got / had oil at the bottom of the ecu connector? Suggest it may be intermittent CAN fault, especially as running ok. (Injector codes) CAN wires are at bottom. Also, push in all of the wires, especially the green yellow wire on the abs block. 23/05 indicates issue in this area/SVS wiring/ earth issue. Option b may be required. Can also test SVS values. Search this forum for how and values.

Hi choc_e, the airflow circuit could mean a faulty MAF, but you're getting pretty good mileage out of it, so as Roverlord says, might just be stored faults from past events. I'd focus on fixing the 3 Amigos for the moment and leave it at that.

I'll be coming to Rocky again in about 6 months, so we can check then if any of the other faults have reappeared in the meantime. I reckon there's a good chance that the injector harness was faulty and has been replaced, which would give you the injector codes. It's worth checking for oil at the ecu though, it can throw up some weird car-stopping faults at times. Cruise control? If it's also working, then it's also likely to be an artefact from a previous repair.

Mine threw open circuit codes when the battery went flat because of a dirty battery terminal on day 1 of ownership.
If you had an event when the battery went flat with engine running and the engine stops with christmas tree dash it could be that.

I've run diagnostics for a few customers and admittedly they all have been driving fine but had a lot of codes. I cleared them for them, not it's just a matter of rereading them in the future. As Phillip. A said battery problems etc can make codes appear.

All those Injector codes can be caused by oil in the injector harness. Mine came up with not oil in it but poor connections.

Happy Days.

If the car is running fine, fuel economy is as expected, no weird things happening, then don't stress it.

The Nanocom is a great tool in assisting to diagnose a problem, but it also reports some really weird things as well.

As said, these could well be "left overs" from previous events. Don't forget, once an event has happened, it will be stored until cleared. And it wont throw an error light onto the dash until the factory set parameters are met.
