ABS Code 15???

Recently, my 1994 Bravada lit the ABS light. It was a 36 - vehicle speed sensor. I replaced the sensor and cleared the codes. The next day, the light turned on again after getting up to 15 MPH. I checked the code and it came back as a 15. I cannot find this code in the listed ABS codes. Any ideas? Thanks.

I don't see code 15 in my '92 book. How do you retrieve brake codes on a '94?

Put a jumper wire between Pin A and Pin H on the Data Link Connector. The ABS light will then flash the codes back to you.

i vaguely remember the abs code 15 being a brake pedal switch problem on the cadillacs, you might want to check that. it's a dual circuit switch, one for the brake lights and the other for the cruise control and abs. test it by seeing if you can set the cruise control and if that works try to cancel it by tapping on the brakes. you might also want to check if your brake lights are working. the easist way to check your brake lights is to get up to speed in heavy traffic and watch the rear view mirror when you stomp on the brakes.

here is a good post on the OBD1 abs codes and how to read them, but no mention of a code 15.
