Hi all,

I need help determining what is going on with Ol' Blue. About 6 months ago, I took a bunch of kids out for lunch, we drove on a fairly rough road in the country - faster than I should have been - much to their entertainment. No problems at all getting there, however, upon our departure to head back home as soon as I put in Drive, she decided she preferred limp mode. I turned Ol' Blue off, sat for a moment, restarted her, and no limp mode successfully drove home. All was right wit the world again and I drove Ol' Blue many times since without issue.

Ol' Blue used to be my daily driver, and over the last year has become my for fun, weekend explorer & errand vehicle. Fast forward to this past weekend and I took Ol' Blue out to run some errands. Stopped at the feed store (3rd or 4th stop of our errand running haul), and when I went to leave she decided limp mode was in order. Out of the blue, was not driving like a maniac as i was the previous time, no rough roads, normal driving, nada. I was about 4 miles form home so I drove her on home and parked her (I know, I know....).

Grabbed my OBDII and the only code I am getting is P1590, I understand P1590 goes hand in hand with 3 amigos (yes, they are there). I have no idea why she is in limp mode and not sure where to start in attempt to determine.

Any ideas? Guessing bad ABS sensor(s), and most likely dirty as I do live in the country and all roads leading home are dirt.

I will try my best to get someone over to help me take wheels & rotors off to clean sensors, just hoping others who have experienced this may want to share their experience and offer some suggestions.

As always, thank you!

 

Pages 44-19 and 44-20 in the Rave Manual have the Limp Home Mode codes and possibilities. Also, what scanner are you using? Maybe it is not accessing the computer that is throwing the code.

 

i got rid of a persistent p1590 by replacing a wheel hub and its associated sensor. cleaning it did not fix it in my case. you need to read the abs system code to work out which wheel is causing the problem.

 

does he need a Nanocom for that ?

 

He needs a scantool that can truly read LR ABS fault codes. P1590 is a generic rough road fault code that is always present with an ABS fault. Autotel, iCarsoft 930/LRII are pretty basic vs say a Nanocom/Hawkeye, but they read LR fault codes.

 

yeah, i have an icarsoft lrii and it reads the abs codes just fine.
if you make friends with a mechanic then they probably have a super high-end device that can read all the manufacturer codes and abs codes too.
