The ABS module was replaced a week ago. The ABS and lightning bolt are both on still. I will try the speed sensor. Thanks

We have had this truck laid up for so long It’s hard to keep track of everything that has been done. As far as I know it only had ABS codes. There’s no sputter or miss. when the driver pulls out and starts shifting and the RPM drops below 1200 into the next gear there’s no foot pedal or accelerator at all if it stays above 1200 there’s no issue usually. One shop said the ABS module wasn’t communicating with the ECM correctly causing the truck to derate. The other shop just said the ECM wasn’t working correctly. (neither shop was very descriptive). Also I don’t have the necessary tools to send the live data sorry.

We have a MP7 that has no foot pedal when it’s cold. If it drops below 1200 RPM it won’t run right or accelerate. After the truck gets going and is warmed up it runs great. We’ve had it in and out of shops and no one can seem to figure out what the problem is. One shop said ECM and another said. ABS module. If anyone else has experienced this problem and got it fixed I’d love to hear what you found. Thanks!
