does HDC work with light on?
so the amigos have paid a visit. or should i say moved in. the lights dont clear, they stay on after restarting the truck. i have an ultra gauge and it shows trouble code P1590. i thought ultra gauge wont read ABS codes?
anyway, id like to go mudding this weekend. does hill descent work at all if theres a code involving it? and it seems P1590 is such a broad code it doesnt help me pinpoint a problem..
thanks guys.

What you can do is check for excess brake dust, or a leaky caliper - I have a leaky caliper that's causing my code.

I'm just going by memory here, but I had a P1590 code on a Discovery and I believe it was for the MAF sensor. If you have five minutes, take a look at the air filter and remove the hose from the air intake to see if anything looks out of place in either area. From what I remember (if I'm thinking about the right error code), I saw a little oil pooled up at the air intake when I removed the air duct. The oil was just enough to cause the MAF sensor to trigger a check engine. You can get some MAF cleaner and spray it down. Let it dry, clear the code, and see what happens. If you see oil, you're probably about to lose a cylinder.
