Three problems related to brake antilock wheel speed sensor have been reported for the 2000 Chevrolet Blazer. The most recently reported issues are listed below.
2000 chevy Blazer - abs system activates at low speed. Has to drive into a ditch to avoid hitting a bicycler. Repair shop said wheel speed sensors are probably corroded. Gm has a recall in 2005 on large suvs but not the Blazer, although it's the same sensor.
The contact owns a 2000 Chevrolet Blazer. While driving 40 mph, the contact attempted to stop the vehicle and the abs engaged. The contact had to apply more brake pressure in order to stop the vehicle. The vehicle was taken to the dealer and the contact was informed that the front hub wheel speed sensor needed to be replaced. There were no prior warnings. The current and failure mileages were 73,640. Updated 12-04-08 the dealer replaced the wheel speed sensors. Updated 12/10/08.
Both brake-abs lights come on intermittently. Vehicle into dealership several times with different diagnosis, even though, speed sensor was mentioned each time but never repaired. Currently, gm recall for speed sensor brake problem does not include 2000 chevy Blazer nor the state of missouri. This is still a ongoing problem on my vehicle.
