1996 Lincoln Town Car traction control braking front wheels?
It seems when I am on slick snow, or ice for that matter, when I try to drive, the traction control comes on but applies the breaks to the front wheels which is obviously counter productive. Is this a problem I can fix or a design flaw?

Re: 1996 Lincoln Town Car traction control braking front...
Your traction control comes on when it notices either your rear tires slipping or front tires slipping and it counteracts the slip to control the slide. It should be working all 4 brakes though not just the front. There is a traction control sending unit under the dash that should be looked at to make sure that it is sending the Trac Control the right message. If it is reading the slide wrong then it should be replaced. Sometimes then can just reset the computer and all works well other times you need to replace the sensor. I would see if they can reset the computer first then go from there. Pleae rate if satisfied. Thank you

YOU CAR HAVE ABS AND TRACTION CONTROL.
IF YOU DRIVE ON ICE AND SNOW TRACTION CONTROL WILL APPLY BRAKES TO ONE WHEEL AND GIVE MORE POWER TO THE OTHER SO YOU WILL TAKE OF STRAIGHT. WITHOUT TRAC. CONTROL THE WHEEL WITH LES TRACTION WILL SPIN AND THE OTHER WILL STAY. MOST COMMON PROBLEM IS ABS SENSOR IS BAD.LET TECHNICIAN SCAN YOUR ABS SYSTEM TO LOCATE THE PROBLEM. REPLACE THE SENSOR AND YOU ARE READY TO DRIVE AGAIN ON SNOW AND ICE.
Ice is a big problem. There is very little traction to be had and managed. It is likely that the system is working, but in icy conditions you simply need to be VERY gentle on the gas pedal. The heavier the car the bigger the problem. Traction control systems will work well in wet or even in snowy conditions, but if you are gunning the engine on ice, nothing will help. You will be out of control.
Hi Correia, Having four wheel drive built onto a vehicle gives traction through all four wheels, meaning that if one of the four wheels looses traction all the driving motion is directed through that spinning wheel. When driving on snow, ice or mud, gently does it all the time! Gentle acceleration and slow down using gentle gear changes. Use the brakes as little as possible. Remember if you lock up the brakes and the vehicle begins to slide you'll have no control at all! Traction control is entirely different than four wheel drive. Traction control will control any wheel which begins to slip and thereby keep you in control. Regards Johngee10
the TCS is traction control system and the ABS is anti-lock brake system, best guess is that you have a bad wheel speed sensor, you can drive it but if you get in a spot were you need eithersystem like ice or snow as long as the lights are on the systems will not work, but it will not hurt anything the car just wont be as good as it could be on slick pavement.
TRACTION CONTROL: An enhancement of an existing ABS system that prevents wheel spin while accelerating on wet or slick surfaces. It uses the same wheel speed sensors to monitor wheel speed during acceleration, but requires some additional control solenoids and a pump to apply braking pressure to control wheel spin. The traction control system brakes the drive wheel that's starting to spin to shift torque to the opposite drive wheel that still has traction. Most traction control systems only operate at speeds up to about 30 mph. Additional control strategies that some traction control systems use to limit wheel spin include reducing the throttle opening, upshifting the transmission, retarding spark timing and deactivating fuel injectors.
If you have a switch for the traction control, the stalling of the engine can be reduced or eliminated by turning off the traction control.
The traction control probably has debris inside the rear emergency brakes. The traction control works by counting the speed of each wheel. When the part that counts the speed is blocked with debris, it thinks one wheel is slipping and kills the engine and applies the rear brake to the fastest spinning side.
The motor is suppose to lose rpm until the wheelspin is stopped. Then the motor is suppose to run normally. If the motor is completely dying you have a terrible problem with the sensor on the rear wheels.
The Traction control needs to be looked at, some Brake shops may be able to fix it. A dealer would have the tools. There should be nothing wrong with the engine, its suppose to react to the sensors.
MAKE SURE TIRES ARE ALL THE SAME SIZE FIRST OF ALL,NEXT MAY HAVE A SPEED SENSOR NOT OPERATING PROPERLY OR BENT OR MISSING EXCITER RING ON FRONT HUB OR REAR AXLE. EITHER WAY THERE IS AN ABS FAULT OR A DIFFERENCE IN WHEELSPEED ON ONE OF THE FOUR WHEELS CAUSING TRAC LIGHT TO ILLUM. VEHICLE THINKS YOU ARE LOSING TRACTION AND APPLYING ABS AND MISFIRING VEHICLE TO SLOW DOWN UNTIL TRACTION IS RECOVERED
Traction Control system adjusts your throttle and braking automatically to help keep your car from slipping on wet/snowy roads. If the light flashes momentarily then that means it is doing the job properly. If the light flashes constantly or stays on then it indicates a problem with the traction control or ABS system and could pose a safety concern.
Traction control systems measure wheel speed differences by various
methods to determine if one wheel is rotating faster than the other. A
heavier buildup of ice/snow could be affecting wheel rotation speed
causing the TCS to engage. ABS works by sensing slippage at the wheels
during braking, and continually adjusting braking pressure to ensure
maximum contact between the tires and the road. Suggest
clearing out the wheel wells now and periodically throughout the winter. Also remove ice/snow
build up between the wheel and the brake pads/rotor.
