ABS Code 61, This solved my problem.

[Sebastian Lundström]

I was searching for a solution for my ABS problem that i have i my truck and didn't find much of an answer, some hints here and there what might be the problem,
So i decided to open up the ABS unit and just clean it with breakclean and compressed air,and also change the brake fluid before removing the unit, so when you put in the clean unit you dont get all the dirt back in the ABS unit
 

1. Here's some pictures of the unit and a link that was helpful. hope this helps

• The ABS unit can be affected by contaminated brakefluid

• after removing the bolts from the "gold" units use a grip tool to pull them out
• NOTE Be careful when removing the electronics

• Nothing special just remove everything now before the clean up

• Nothing special about this picture just remove everything before the cleanup.

Wow you are a brave man Chevy and GMC Trucks ABS systems are infamous for erratic behavior usually due to lack of maintainance hence dirty or low fluid rusty or dirty sensors etc I always keep fresh clean fluids top offed and replace pads shoes on time to try n avoid headaches but even still have had a few abs episodes myself...usually new pads and fluid top off fix these issues but a couple were nightmares usually just pulled abs fuse n dealt with dreaded dash light or attempt to bleed system resilting in spongy brakes or death wobble so i always TRY TO AVOID OPENING BLEEDERS AND BRAKE LINES AT ALL COSTS due to my past mistakes so I give Props 2 any man who can and have their truck stop same as before or better...Good work!
