If your final drive control module has not to be updated and also the code is stored her repair process will likely begin with a flash of the FDCM together there is a flash because that the FDCM that doesnt point out applicable dtc"s it simply states "if the password is stored". From over there it could be the transfercase, the FDCM itself, wiring, your 4lo switch....
I had actually the same stuff-flashing FCDM did it because that me. I still don"t agree with having actually to pay for a re-flash, if it"s identified in a TSB....
There are tons of reasons it can come on, so having actually it scanned is the best method to accurately decide the cause and also troubleshoot. When it involves things prefer this (or other things that require the dealer come scan), ns wait until I am going there because that something else like an oil change, and also then i ask castle if they can just scan it actual quick since it is already in the bay and also the tech is currently there. I have never had to pay for them to scan and also look something up..
On mine 06 XK, it come on, and since I execute not usage 4x4 in Florida, that didn"t issue me in ~ all. It continued to be on for quite a while before I take it it in. It had actually a code stored because that clutch wear, but they looked fine. I had actually the code cleared and it has actually never come back on. Some people have the blog post come on, and can still engage 4Lo however some can not. I had actually one of the situations where 4Lo would certainly not engage with the article on. I am not certain if that still had permanent 4WD, since I never ever take the XK in a case when it would certainly be needed. I simply know i tried to connect 4Lo and it would certainly not.
These are constantly 4wd they cant be shifted into 2wd favor the old ones.When mine popped increase it was simply a wheel sensor.
Build thread:Whoa"s develop thread You think that"s quick................heh...wait till ns hit 5th! -Sir Mix-A-Lot
I"m not as well worried around it because it went off, must mean its nothing major. Likewise have no use for the 4WD appropriate now due to the fact that it hasn"t snowed any.
