Ok. Does it matter if the steering angle LOOKS pretty reasonable (I was looking at that today as one of the live values)? Or does recalibrating it, regardless of how accurate it already is, still reset something?

 

I must be calibrated when installed. If it is off by only a few degrees then the truck assumes there are issues because the wheel speed sensors do not match what should be a turning truck. Take only couple seconds to calibrate anyway. Best to drive down a straight road for a hundred feet so the truck is pointed dead straight to take out any tilt you may have in the steering wheel. Unless you have a good alignment and the wheel itself does sit nice and proper. Then just calibrate it as you sit - again just make sure you wheel is exactly as it should be as if you were driving dead straight.

 

Ok, thanks. I'll try that. Probably won't be for two days until I get a chance to do it.

 

Still no luck. I went out and calibrated this morning before work. It was off by about nine degrees, but calibrating it didn't get rid of the three amigos. I'm starting to wonder if I'm missing passing on some important information or something. After clearing codes and rescanning I have the same three codes as always:

Once again, last night I left the suspension in Off-road height and pulled the fuses. This morning the right rear corner was on the bump stops (leaking air bag) and the other three corners were still inflated. Started the vehicle and the compressor topped up the reservoir with no changes to any of the suspension heights. Started to drive and it got the amber suspension dash light, a "suspension lowered" message on the info screen, and the right corner raised to (roughly) Access height and the other three corners dropped to (roughly) Access height.

Calibrated the steering, reread codes, same three codes and the three amigos on. (sigh...)

 

Nice degrees is nuts. At this point, try a hard reset. Disconnect battery for 10 minutes. Lets just clear all the crap out and see if that works. From there forward we go. But I see no code that would cause your faults. That is why I suspected the steering sensor since it can be way off, cause lots of math issues but not actually generate a fault.

The only code that is odd is that low freq coil. I really have no clue what that is about. Unless the body control module is having a really bad day and causes all these other faults? It could I suppose.

 

Ok, I did do a hard reset yesterday, but that was before calibrating the steering angle. I'll try to get the hard reset done tomorrow.

 

Ok, I just realized that I have been posting bad information (hard to troubleshoot when the correct information isn't provided! ). I was thinking that the three dash lights that I have on are referred to as the "three amigos", but I think I have different lights on. The lights that I have on are: ABS (red), Brake systems (red), and Dynamic Stability Control (amber). These lights have been on the whole time and nothing that I have tried has extinguished any of them. I also have the Suspension (amber) on now, and it normally comes on once I start driving, but always clears when I clear faults.

I did a hard reset today. Disconnected the battery cables, waited a few minutes and then shorted them together. Left them like that for about fifteen minutes and then reconnected the battery. I had pulled the suspension fuses so just the leaky right rear corner was low. As soon as I started the vehicle the ABS, Brake systems and DSC lights all stayed on. The reservoir had leaked down a bit so the compressor fired up to bring the pressure up to 258psi. I cleared codes and then checked them and got:L319 - LR3 2006

I started driving and right away the Suspension (amber) light came on and the right rear corner inflated to Access height and the other three corners dropped to Access height (I'd left all four corners higher than access). I checked codes again and now had:L319 - LR3 2006

Any new suggestions with this information and my correction on which lights are illuminated on the dash? Does the ABS need to be read with a different tool, or why doesn't the Gap Tool show anything related to ABS when the ABS light is on?

Thanks!
