Driver came to the shop today and told me that as he was slowing down for a stop sign ahead. Driving on slippery snow covered road he put the truck in neutral and applied the brake the ABS activated due to wheel lock up but the strange part is when that happened the engine RPM raised to 2000rpm and came back to idle ( good thing it was in neutral ).
He was able to re create the issue a few more times and it only happens during an ABS event. Has anyone heard of this before ?
