A CRUISE CONTROL ELECTRONIC REGULATOR (CCER) IS PROVIDED WITH THE TRUCK CHASSIS, AND IS MOUNTED ON THE CHASSIS ACCORDING TO INSTRUCTIONAL DRAWINGS PROVIDED BY OSHKOSH. SOME BODY BUILDERS HAVE INSTALLED THE CCER OUTSIDE THE PASSENGER COMPARTMENT. IN THIS LOCATION, MOISTURE CAN ACCUMULATE AROUND THE CIRCUIT BOARD CAUSING A SIGNAL TO GO TO THE VACUUM PUMP OF THE CRUISE CONTROL, WHICH PULLS THE THROTTLE TO A "FULL OPEN" POSITION WITHOUT WARNING. DEPRESSING THE BRAKE OR TURNING OFF THE CRUISE CONTROL SWITCH WILL INTERRUPT THE SIGNAL.
RiskA "FULL OPEN" THROTTLE OCCURRING WITHOUT PRIOR WARNING CAN RESULT IN LOSS OF VEHICLE CONTROL AND AN ACCIDENT.
FixALL CHASSIS MANUFACTURED FROM FEBRUARY, 1991 TO APRIL 1993 WILL BE RECALLED AND OWNERS NOTIFIED TO HAVE THE CCER MOVED INSIDE THE PASSENGER COMPARTMENT IN A DRY ENVIRONMENT.
