Try pulling battery for ten minutes or so and see if that clears any of the codes if not use a obd11 code reader and that should give you a correct answer

1.Why is my break light indicator on dashboard on even when break is not engaged.Note,my break is active and fluid level is ok. 2. Why is my ABS light on and refused go off from dashboard.


Not sure about the Honda setup, but when my Dakota had those lights both lit, it was a bad speed sensor in the system. I had the additional symptom of no speedometer reading until about 30mph.
It seems that the VSS in my system was used at lower speeds by the ABS system to determine when to activate. If the ABS light goes on, many vehicles will also activate the brake light since the two are undoubtedly related.

Honda motorcycle abs


An ABS sensor is not a magnet as such, it has a resistance of approx 1,5 ohms, it has a minor magnetic field when the ignition is on, the interruption's of that field by the reluctor ring generate approx 0.5 volts AC signal to the ABS ECU to indicate wheel speed. There should be no lights on with the ignition off, the ABS ECU has possibly stored a fault, needs to go on a scanner.

1998 dodge Dakota Ok so I just got this truck and when I got it the abs light and brake light were on plus the speedo doesn't work sometimes I replaced the rear speed sense on the diff but the lights...


If the red brake light and the ABS light are both lit up on the dashboard, do NOT drive the vehicle. It indicates a major malfuntion with the brake system. The red light indicates low brake fluid or the parking brake engaged. The yellow ABS without the red light, indicates a problem the computer found and it disables the ABS system while still having conventional brakes. Since both are lit, it needs the brake system repaired. What you replaced on the rear diff was probably the rear ABS sensor. The vehicle speed sensor for the speedometer should be located on the rear of your transfer case if you have 4WD, or on the rear of the trans if you have 2WD.

Changed brake pads and fluid. Brake light/ABS light still lit.


Go back around and check to make sure you didnt accidentally pinch or cut a brake pad sensor. Also the ABS modules on VAG cars are pretty crappy.

the tell tail is on the hub and drum. a sensor at each location. you will see the one that is bad. it will be burnt. the speedometer does not have anything to do with it. it is a separate problem. most cause of speedometer problem is at transmission.

Erratic speedometer with ABS and brakelight lit


same problem here, found 3 places that say it is the abs sensor:

Had this problem with my 1999 Ram 1500. There is a sensor at the top of the rear differential for the ABS system. That sensor went bad and replacing it took care of the problem. What caused mine to go bad was apperantly water got into the differential when launching and loading my boat. check to see if gear lube needs to be replaced also.
The answer above is perfectly correct. When the ABS sensor on the diff goes bad the speedo no longer will work, the odometer stops recording mileage and both brake and ABS light comes on. You also loose O/D or "Lock-up" in the torque converter. The sensor is inexpensive and can be changed in about 30 mins. Good Luck!

The fix for your truck is the ABS speed sensor located in the top of the differential housing , held in with one stud . Your speedometer is calculated through the ABS controller. Replacing that sensor will fix your problem.
