THE ABS AND TRACS OFF IDIOT LAMPS TURN ON AND OFF INTERMITTENTLY IN MY 850. I CAN BE DRIVING AROUND ON DRY PAVEMENT WITH VERY LITTLE THROTTLE INPUT, AND THE TRACTION CONTROL WILL ENGAGE (AUDIBLE WHIRRING OF THE ABS MODULATOR PUMP AND STIFF PULSATING BRAKE PEDAL - QUICKLY APPLIED TO CONFIRM MY SUSPICION). THIS WILL LIGHT THE LAMPS. LIKEWISE, I CAN BE BRAKING ON A DRY SURFACE AT A LOW DECEL, AND THE ABS WILL ENGAGE. THIS WILL ALSO LIGHT THE LAMPS AND SHUT OFF ABS/TRACS. AFTER A WHILE, THE LIGHTS WILL TURN OFF, AND ABS AND TRACS FUNCTION NORMALLY. THIS HAPPENS ABOUT ONCE OR TWICE A DAY SINCE THE FIRST INCIDENT ON 7/11/03. I'VE GIVEN AN ESTIMATE NUMBER IN THE FIELD BELOW. FURTHERMORE, THE SPEEDOMETER FUNCTIONS INTERMITTENTLY. I'VE TRACED THIS ISSUE BACK TO A FAULTY CONNECTION BETWEEN THE VEHICLE WIRING HARNESS AND THE ABS CONTROLLER. THE TIMES THIS HAS HAPPENED, THE WIRING HARNESS HAS NOT BEEN FASTENED SECURELY IN THE PLUG ON THE ABS CONTROLLER. REMOVING AND REPLUGGING THE WIRING HARNESS INTO THE ABS CONTROLLER TEMPORARILY SOLVES THE PROBLEM. THE WIRING HARNESS IS COMING LOOSE IN NORMAL DRIVING CONDITIONS. THE CAR IS WELL MAINTAINED AND IS NOT ABUSED. THIS HAS HAPPENED TWO TIMES SINCE THE FIRST INCIDENT ON 7/11/03.*JB

I NOTICED AN ODD NOISE WHICH SOUNDED LIKE SOMETHING ROLLING AROUND IN THE BACK OF THE CAR, BUT NOTHING WAS. AT TIME OF STATE INSPECTION, I ALERTED THE INSPECTORS. THEY FELT SOMETHING BUMPING FROM WITHIN THE GAS TANK. I DISASSEMBLED THE FLOOR COVERINGS AND INSPECTION PORTS FOR FUEL PUMP AND GAUGE SENDER. I REMOVED THE GAUGE SENDER AND LOOKED INTO THE TANK AND OBSERVED A PLASTIC BOWL-LIKE OBJECT SURROUNDING THE FUEL PUMP. I ROCKED THE CAR AND THIS BOWL WOULD SLOSH AGAINST THE PUMP. THIS OBJECT APPEARS TO BE A BAFFLE TO REDUCE SLOSHING AROUND THE PUMP. IT WOULD SEEM THAT IT WAS INTENDED TO BE GLUED IN PLACE, BUT HAS BROKEN LOOSE. I SUPPOSE THAT THIS WOULD EVENTUALLY DAMAGE PUMP OR TANK. A NEW TANK WILL COST CLOSE TO $400 WHICH I WILL NOW ORDER. ADDITIONAL PROBLEM IS INTERMITTENT FAILURE OF ANTI-LOCK BRAKE/TRACS SYSTEM MODULE.*JB

I HAVE NOT YET REPLACED THE FAULTY ABS MODULE ON MY CAR BECAUSE NO ONE KNOWS EXACTLY WHAT THE PROBLEM IS. I HAVE RESEARCHED IT AND THE ABS MODULE HAS BEEN FAULTY ON MANY VOLVO 850.
