ABS & Brake lights on
Hello,
I am working on a 2000 Ram 1500 sport 4wd quad cab rear abs. Came to me with a leaking frame brake line and ABS light on. I have replaced all the brake lines with NICU lines, all hoses and Master cylinder also replaced rear wheel cylinders and front calipers. I also replaced the ABS sensor in the rear axle. When I received the vehicle it showed codes 36 no signal from the rear sensor and 72 ROM Checksum. After doing all the work and resetting the DTC's I am now getting the abs and brake light on after about 3 or 4 times applying the brakes. After shutting the truck off and back on again the lights are off again until the brakes are applied 3 or 4 times again. I have scanned the truck and it shows no codes present. Any help would be appreciated.
Thanks,
Steve

I bled it using a vacuum bleeder first. Then I rebled it by the manual brake pedal way seemed to push the fluid out decent. do you think this could be the problem?

May be the proportioning valve just isn't *quite* in the right spot. Grab a friend, bleed all four corners again. Take it out, find a dirt road, STOMP on the brakes. (make the abs do its thing. lites have to be off for it to play nice.) Re-bleed the brakes. Should be golden. (hopefully)

I will check it out tomorrow. I will replace it and rebleed. I will try to get a picture of the over bent line too. hopefully, this will fix it.
