Multiple sytem faults (HSC, trans. Parking brake, cruise ctrl, ABS)
Hello everyone...I've been browsing the site for the past couple of weeks as a guest. I thought it was time to take the plunge and get my feet wet so to speak. I have a new (to me ) 2005 LR3 as of last month. Unfortunately, it has been bitter sweet the past couple of weeks because of the multiple sytem faults (HSC, transmission, cruise control, ABS, etc), unshiftable "F" gear selection, and lowered suspension.
I realize these are common problems with the 2005 (and newer) LR3 model year. I've scrubbed the older threads and taken some corrective actions as follows:
Replaced with new battery. Didn't get an Interstate replacement, but the one I did get has 950 CCA. This worked fine for 2 days, then the same faults showed up.
I then replaced the Brake Light Switch as often recommended in other threads. And yes, there was black dust in the old one which may have caused some arcing/voltage irregularities. Interestingly enough there was a brand new LR brake light switch in the glove box. I wonder why?
Unfortunately, No luck, All the faults, including the ********* "F" gear indicator, with inability to shift, as well as the Christmas tree lights and lowered suspension were still there.
I've got one idea which I would like to run past all of you. I talked the dealer into replacing the tires on the truck before I bought it. The only thing is - the tire height was 65...They seemed concerned about not having 55's(?) in stock, but their tech made sure the higher tires 255/65/18's would not rub, and then sent me on my merry way...I just have to wonder if the height sensors are confused with the added inch, or so, of height and causing all the crazy errors to occur. So far all my other efforts have shown little to no results.
I understand from my research on this forum that the more faults that appear at once are generally a better sign of a smaller problem than just having one specific fault appear. That sounds promising to me, but I've run out of lower cost options. What do you all think about my tire height theory? Any thoughts on other things to troubleshoot?
(Edit) BTW, I tried a hard reset (as per instructions found on this forum) with no luck. I also unlpugged the tail light lenses to see if it was a bulb problem, but there were no changes. BTW, all bulbs appear to work fine, and filaments (the ones I can see) are in the vertical position.
