I even asked the parts guy about the "cap" and there isn't even a part number for it nor does it show up in his parts diagram. I had to show him the picture from the manual...I wonder if we could fashion a suitable replacement???
I'm having the same problem with my 05 LS I replaced the brake caliper that was stuck on the right rear rotor but didnt stop giving me the service parking brake plus the abs as well but what I have noticed is that when I reset the ecm by disconnecting the negative cable on battery and when asked to set parking brake it makes a clicking sounds then the service the parking brake light comes on any idea on how to fix it much appreciatedIt's probably a failing/failed parking brake cable, though it could also be a bad caliper or a bad module.
I don't see a way to repair a cable that wouldn't fail very soon. If the calipers check out as working correctly, then I'd replace the left and right parking brake cables (not sure why you are picking on the driver's side cable). The passenger one seems to fail more often, but once one goes, both should probably be replaced.
AFAIK, the only source for the cables is the junkyard.
Ok thanks for the advice and info much appreciated I was so relieved when I got it out of limp mode then after changing the brakes this started happening so my next step is to check those cables I've never had problems with them so this will be my first time doing them il give you an update once I get it done and hopefully that was the problem so I can finally go back out cruisingI would start with a good inspection of the mechanical cables.
