2004 Honda Accord abs and tcs lights are on ..how do I fix it myself?

Only if the warning light showed on the dash...most often these abs sensors get clogged with brake dust or dislodged during wheel swaps if the pads are fine and fluid level correct...first check the brake pads then the disks and clean the sensors with an old toothbrush and reseat, also check the fluid level on the abs system.this should clear warning light.but any error codes stored on ecu need to be cleared using obd.

if the car is a 6cyl it might have a bad alternator that will put all the dash lights on, the vibraion could still be the
front rotors have them cut on the car

TCS = Traction Control System

The TCS light is on because the check engine light is on this is common repair the check engine light failure abd the tcs will go back to normal.

You need to check the code to see if it is a trans code and then if it falls under the bulletin limits Honda will replace the trans under warranty. Even if you are out of warranty Honda will sometimes do a partial warranty. Here's a copy of the Bulletin.

There are several things that will turn the check engine light and tcs light on .if you get the code I can tell you exactly what the problem is . on your year i see transmission problems as well as egr problems. if you go to any large auto parts store they will check the code for free or a very small fee.

Hope helps (remember to rate this answer).

Change your oil for the TCS.

check inside the e brake lever sometimes loose change falls in there causing contact with the light contacts.the problem is in the e brake lever switch look for pennies or other change, or something in its way.

some markets have a button on the dash with tcs/abs and a dash light saying "tcs off".if your car has not got the button then you cant turn it off(germany yes.uk no)abs/tcs should only be turned off in deep snow,otherwise best left alone,unless you have been taught how to drive with/without.....(on ice you wants the wheels to turn,on snow you want the snow to wedge to slow you down......)see what i mean???

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

You may have more than one code.
You may need a ABS sensor if the TCS light is coming on.
Check the codes again.

no that does not seem right i would take it to a autozone and have them trouble shoot the code and then take it to a dealer and have them look at it

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 .
