1998 Pontiac Grand Am
3.4
Lights = brake light and abs light
codes = rear abs channel will not move
GM tech = any
question = I have no idea what this code means its driving me nuts what
is a channel and where is it in the abs? And why won't it move lol
thank you
JK:
Sounds like you are getting code C1246. This code refers to a condition where
the Brake Control Module (EBCM) cannot control the ABS channel to the rear
brakes. This is usually caused by an ABS motor pack problem, or a gear has
come loose on the bottom of the motor pack. Some diagnostics with a computer
scan tools that can control the ABS system is needed.
VISITOR:
Is a abs motor pack the same thing as a abs module because they are
like $600-$1000. And I found one at a junk yard for $50 bucks? Thanks a
lot!!!!
JK:
The motor pack and the modulator assembly are 2 different parts. But at the junk
yard, they may still be bolted together and sold a unit.

Anti-lock brakes are designed to prevent skidding and help drivers maintain steering control during an emergency
stopping situation. In cars equipped with conventional brakes, the driver pumps the brakes, whereas in cars
equipped with four-wheel ABS, the driver keeps a firm foot on the brake allowing the system to rapidly and
automatically pump the brakes. Because the wheels don't lock up, drivers have the ability to steer around hazards if
they are unable to stop in time.
When the braking force created by the driver is greater than the tire can handle, the wheel can lock up. Locking
wheels can create vehicle instability problems and prevent steering around obstacles in the road. Stopping distance
on many slippery surfaces will also increase with locked wheels. Four-wheel ABS prevents wheel lock-up in
situations in which the wheels might normally lock, such as on slippery roads.
