Sorry about this being in the wrong forum, can't seem to make a post in the DIY forum...

Anyway, recently bought an 01 1500 4x4 with the 5.2 manual.
Check engine light was on, code indicated a bad PCM.
Replaced it and the engine light went off, but now the ABS and BRAKE lights come on. After searching this and other forums I replaced the RWSS, but the lights still come on.
The lights come on after the ignition has been on for a minute or so, whether the truck is running/moving or not. Can't find any pinhole leaks in the brake line. Plenty brake fluid.
Any ideas??? Thanks in advance!

 

Adjust rear brakes (self adjusters in these are almost useless) and then bleed brakes. Start with right rear, then left rear, then right front, then left front.

See if that clears it up.

 

gotta take it to the dealer and have the pcm flashed with your vin. that will clear the code up.

 

Was at the dealer today and was told the PCM was already flashed?
Bought the PCM at Orielleys and they took my vin and mileage when they ordered it. When it got here they said the company that remanufactured the PCM wasn't able to program for a Dodge, and that I needed to see a dealer.
Dealer jacked with it for an hour and said it was already flashed..?

 

+1. Or do what I did and put a piece of tape over the light If it's been reflashed with your vin then the light should be out.

 

....or, find out why the lights are on........

 

Thought about covering and forgetting about it, but I'm kinda one of those guys that has to have everything just right...

Any chance the dealer didn't know what they were doing and didn't flash it right? He said "it's already got all the updates..." but he just gave me a weird look when I asked him about the vin and mileage.

 

Check with another local shop, and see if they can't verify VIN for you.

 

+1..... The vin needs to be correct for the ABS module to work.

 

Still having fits with this one...
Dealer says PCM is flashed, mechanic and company that I bought the PCM through say it isn't, and SOMEBODY IS WRONG! Lights still on..!
