painful but this is what it takes to get to DTC P1111 ( all systems go) I drove my car 800 km (8 hours)yesterday on the highway only (not muchcity driving) after erasing all codes, I started with the P1000 and just checked now, still P1000 - waiting for one of the below to be finished before getting a P1111 my code reader shows each test below. For sure the dealer knows all this and they know what drive cycle they are doing. It is just so complicated that they dont explain the whole thing to customers.

Bo,
Thanks for the reply! The dealer completed the cycles. Now the underlying problem is the mdssoftware will not communicate with my car. I took my X to a non Jag mechanic who works on Jags and the hooked up globally to my car and nothing! None of the systems they use can communicate with my car. Now the non Jag tech said that I could have a corrupt down load in my car which only Jag can update. Does that sound like it could be it? Also, my front driverside turn signal they cannot fix. They changed the light bulb and the whole assy. When I talked to the non Jag tech he looked up online a recall of of MitchellOnDemand and said he found a recall regarding the modules not working. Does that sound right? Could it be something else?

My 02 had a recall to replace the module that runs the turnsignal.. ( and many other things) the defect was not very serious, there were times when the bulb was burned out and the dash indicator would work normally. The drive would never know he had a burned out bulb.
I dont think that you specific problem is part of the recall... but if your car is due to be done.... then get it done.. you get a new turn signal module and that may solve your problem
I dont know what your communication issue is. I dont understand why the dealer cant get to the bottom of it. Seems to me that is what they do for a living?
