The ABS and TCS lights both came on simultaneously in my Odyssey. Brake fluid is fine, pulled and checked ABS fuses under hood and on passenger side and all fine, tried to re-set by disconnecting negative battery cable, and still came on. All brakes are fine in vehicle - just put new pads and rotors on front wheels about 4 weeks ago. Wondering if possibly a wheel speed sensor or something else? Sensor lights actually went off once while driving, again about 2 days later when starting vehicle. Have stayed on continuously since. Any ideas?

Hi rkruszka. Welcome to the forum. When the ABS light comes on it means the computer has detected a problem, usually with the sensors, but there are a lot of other possible causes. You'll need to find a mechanic with a hand-held computer, called a scanner, that can access that computer on Hondas to read the code(s). The traction control light will also come on because it uses the anti-lock function in its operation.

If you find the light does not turn on until after the car is moving, suspect a cracked tone ring, usually on one of the front cv joints.

Check your battery first, make sure more than 12.5v, if less than 11.5, replace/swap the battery, it's a quick check, you may get lucky and save you $1,000 from dealer. Good luck.
