Message: [QUOTE="Tommikaze, post: 1557449, member: 34202"] An update for people searching for a repair to the C1241 ABS code on Ford trucks (1999 F-350 with rear wheel ABS in my case). I had to slam on the brakes to stop for an emergency vehicle passing. The ABS fired during this stop and the ABS light immediately came on. I cycled the key and the light stayed on. Connected a scanner when I got home and found the C1241 code. Searching the internet didn’t give much info beside this post and a couple others. Those posts suggest replacing the “ABS Module” behind the LH headlight. The problem is that part is not available so you have to get it from a junkyard or EBay (if one is even available). Since the ABS firing is what caused the code I decided to play around with the ABS braking to see if I could figure out what made it throw the code. I cleared the code but it would come right back on if I cycled the ignition. If I cleared it after the truck was running I could drive about 3 miles before the light came back on and threw the same ABS code. I decided to make the ABS fire during the time the light was off (ABS won’t work if the light is on). I did this by slamming on the brakes at low speed (about 20-25mph). You can also do it in gravel because that makes the ABS fire easier. I did it until the ABS light came back on (about 3-4 times). I cycled the ignition, cleared the code and made the ABS fire one more time. The ABS light did not come on and when I cycled the ignition it did not automatically throw the C1241 ABS code like it had been doing. I’m pretty sure what happened is the valve assemblies in the ABS hydraulic unit were getting stuck because the ABS doesn’t fire very often. When I did have to use it the valve stuck causing the code. By forcing the ABS to fire it worked the valves until the freed up and stopped causing the fault that creates code C1241. I hope this post helps someone with this code and saves them buying parts. My truck has been fine. No ABS light since the last time I got to the ABS to fire and free up the valving in the hydraulic assembly. [/QUOTE]
