The problem
AN OPERATIONAL AMPLIFIER IN THE AXLE CONTROLLERS ON THE INVOLVED VEHICLES MAY DEVIATE FROM SPECIFICATIONS. THERE MAY ALSO BE AN OPENING IN A SOLDER CONNECTION BETWEEN THE PRINTED CIRCUIT BOARD AND THE NEGATIVE TERMINAL OF THE CAPACITOR. THESE CONDITIONS CAUSE THE ANTI-LOCK VALVE SOLENOID TO BE ENERGIZED CONTINUOUSLY.
What owners should do
THE INCORRECT CONTROLLER WILL BE REPLACED WITH A NEW ONE.
