The problem
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS. THE ANTILOCK TRACTION RELAY VALVES WERE INCORRECTLY ASSEMBLED BY THE SUPPLIER. AN EXTRA CHECK VALVE WAS INSTALLED WHICH WILL NOT ALLOW THE TRACTION CONTROL SYSTEM TO FUNCTION PROPERLY.
Risk
THE REAR BRAKES CAN BE APPLIED AUTOMATICALLY DURING A TRACTION EVENT AND NOT RELEASE UNTIL THE AIR SYSTEM PRESSURE IS DEPLETED.
What owners should do
DEALERS WILL INSPECT THESE VEHICLES AND ALL ANTILOCK TRACTION RELAY VALVES FOUND DEFECTIVE WILL BE REPLACED.
