Abs activated on dry road while stopping on a slight grade . This resulted in a loss of brakes as if a brake line failed. I shot forward about three feet then all four wheels locked up. After the accident the ABS light came on so when I got home I had my mechanic check the codes. The ABS control unit was bad but gave no indication until after the accident. The mechanic told me that this wasn't the first time he had someone with a99 - 02 gm truck in his shop with this same problem . For me this failure resulted in $5000.00 damage to my truck as well as damage to the vehicle in front of me (which luckily we also own).I just got a recall notice today almost three months after the accident for the ABS speed sensor that causes this same type of malfunction but what about the control unit on the frame rail ? In this case it also failed and costs almost $1000.00 just for the part alone before it is replaced. That's over $6000.00 by the time every thing is fixed.

Vehicle speed control
- What is wrong
- These vehicles were assembled with the throttle cable contacting the dash mat which could bind the throttle. This does not meet with the maximum return times required by federal motor vehicle safety standard no. 124, "accelerator control systems."
- Risk
- Consequence of non-compliance: the engine speed may not return to idle increasing the potential for a vehicle accident.
- Remedy
- Dealers will inspect for adequate throttle cable to dash mat clearance, and if there is insufficient clearance, cut out a portion of the dash mat to provide proper clearance.
