    Hello,

    I was wondering if anyone could suggest the next step for me in this issue.

    I changed the front right bearing, which I had done before. When I test drove it, the lights came on.
    I did the paper clip jumper and everything was ok and then reset it with the 8 pumps of the brakes.
    When I started the car, the lights turned off, but when I drive it about 100 yards, the lights come back on.
    I checked the brake fluid level and all good. My battery was replaced about 2 years ago, so I dont think it is that.

    Any ideas what to look for next? Thanks for any help

    Pull the speed sensor and see if there's anything stuck to the end. Check the cable is plugged in and routed properly.

    Check to see if that dust cap that protects the tone ring on the CV axle is still there, and that the hole in the dust cap is lined up with the hole in the steering knuckle.

    That's all I got offhand.

    If the warning lights are on, you have trouble codes that need to be read. Once you read the trouble codes, come back and post them for further help.

    Thanks everyone. It was the speed sensor. I took it off and had some debris on it. Cleaned it up, reset using paperclip, and all good now.
