White Truck Recall 78V132000: Service Brakes, Air, Antilock, Control Unit/module

NHTSA recall 78V132000 · announced June 12, 1978 · filed by White Motor Corporation · 39 units affected

The problem

THE INVOLVED VEHICLES MAY HAVE BEEN BUILT WITH POWER UNIT ANTI-SKID LOGIC MODULES ON TAG AXLE INSTALLATIONS INSTEAD OF THE CORRECT TRAILER TYPE MODULES. SINCE THE TAG AXLE SENSOR OUTPUT IS LESS THAN THAT OF THE POWER UNIT SENSOR, IT REQUIRES THE MORE SENSITIVE TRAILER MODULE. AS SENSOR OUTPUT OVER TIME DROPS BELOW MINIMUM REQUIREMENTS, ONE OF TWO THINGS WILL HAPPEN: (1) THE ANTI-LOCK SYSTEM ON THE TAG AXLE WILL SHUT DOWN AND THE CAB MOUNTED FAULT LAMP WILL LIGHT OR (2) THE SYSTEM WILL BECOME INOPERATIVE WITHOUT ACTIVATING THE FAULT LIGHT. THIS FAILS TO CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKES".

What to do

DEALER WILL REPLACE THE INCORRECT ANTI-LOCK MODULE WITHOUT CHARGE TO OWNER.
