Questions To Ask The
Driver
Has the sensor been changed
recently?
Does the mounting bracket look
damaged or tampered with?
Did the ACB sensor currently on the
vehicle come from another vehicle?
With cruise control "set", does the
system consistently bring on the
foundation brakes when a forward
vehicle slows?
Does a trouble code seem to occur
when driving through the desert
or in barren areas (no road signs,
trees or vehicles)?
Does the system seem to disengage
after an automatic braking event?
Does cruise control disengage
sometimes when the brakes come
on and not at other times?
Does the connector or wiring
appear damaged?
Does the system generate a trouble
code going down a grade, but the
code goes away later?
Does the sensor have noticeable
d a m a g e b e y o n d n o r m a l
discoloration or surface scratches?
