Question about 2002 Hyundai Santa Fe

2 Answers

ABS and TCS light comes on, brakes seem to be on while driving.

My ABS and TCS light comes on intermittently for no reason. Also, with or without the light coming on, the car does not seem to accelerate and feels like the brakes are stuck on. The RPM will go up, as well as the accelerate, but does so very slowly. When I push the brakes they are extremely difficult to push in as if the ABS are on. Subsequently during this time when I take my foot off the gas the car slows almost immediately by itself.

Does anyone know what is going on or how to fix it?

    My TCS light comes on when driving on the highway after I get up over about 70. It flashes on for a few seconds I lose accleration and then it goes off and I can accerlate again. Happened intermiddantly (maybe when I hit bumps?) I did not even know what that light was for until now. I am hoping it could just be a sensor??? My ABS light does not come on.

Abs & TCS-off dash lights both stay on. Pushing the TCS off switch does not help. "seem" to stop fine. Emergency brake seems to be fully off, not dragging. My wife encountered a patch of ice...


Hello: If there is a problem in the ABS it will bring on the tcs light as well. To determine what is causing the problem you need to have the ABS checked with a scanner to get the code. Then trouble shoot the components that the code leads you to. Normal braking is available with the light on but TCS is not as it relies on ABS for functioning the TCS.

Tcs/abs lights keep coming on after I had the two sensers replaced on the frount wheels allso now the break light comes on wile driving. the car is a xg350L


The tcs/abs and brake lights are all on the same warning circuit. First i would check the brake fluid level and make sure it is topped off, next i would have the problem codes read and see if it helps you pinpoint the issue. If the light sometimes come on and sometimes are off i would suspect connection problems in the wiring. hope this helps

TCS light comes on


the tcs is ur traction control system this reads the wheels and if one slips cuts down power to engine so as not to damage engine or trans also if awd will activate the other wheels for traction the sensors are usually part of the abs[anti-lock brakes] check connections and wires as well as the sensors at the wheels and transmission -since the light is intermittent which would indicate a short or a sensor is about to fail the vehicle will store the code as pending -have vehicle scanned some auto stores do this for free such as auto zone/ advanced auto check ur local area the code will tell u where the problem is coming from

TCS light on


The TCS (Traction Control System) indicator comes on or flashes under the following conditions:

When you turn the ignition switch
to ON (II).

When you manually turn off the
TCS.

It flashes when the TCS is
regulating wheelspin.

If the system's diagnostics senses
a problem in the TCS, the indicator
will come on and stay on.

If the brakes overheat, the
indicator will come on.

If the TCS indicator comes on and stays on for more than 10 minutes while driving, pull to the side of the road when it is safe and turn off the engine. Reset the system by restarting the engine, and watch the TCS indicator. If the indicator remains on, or comes back on while driving, have the system inspected by your Honda dealer. You can still drive the vehicle without TCS.

This indicator will come on along with the ABS indicator if there is a problem in the anti-lock brake system.
The TCS indicator may occasionally come on for one or two seconds and then go out. This is normal.

Hope this helps you figure it out.

TCS light & ABS Light on/off intermitent


usually when there is an interuption in current flow you will get flickering indicator lights on the dash. This means one of two things, either the sensors that control those indicator lights are becoming faulty or the alternator may be on its way out. One thing you need to keep in mind if you ABS unit is on its way out you will not notice any difference in drivability. ABS is just a brake assist(Antilock Brake System) when it fails you don't lose your brakes you just stop like a regular brake system would without an assist.(ABS) Maybe the unitis on its way out as well.. I would ge it checked as well.. Good Luck

2002 honda accord tcs light comes on and will not go off


I assume tht is traction control. Check fuses ,eeven abs fuses ,traction control is part of abs. If fuses ok will need scan tool to find cause of lite going on. Most common are abs sensors and broken abs wires. And if abs tone ring is part of axle shaft some rock may have damaged teeth of ring .

2004 Lexus SC 430 brake & ABS light comes on without braking


Well ABS stands for Anti-lock Braking System. The reason that kicks on is so your brakes don't lock up on you on certain terrain so that's not bad. But you said your brake lights are bad, check the wiring to them for any bare wiring to make sure none of the metal is hanging out of the insulation rubber.
