Cruise Control Module Adjustments
The cruise control module adjustments are pre-
set by the manufacturer. If all other components
of the system appear to be functioning normally
and the cruise control remains inoperative,
perform the following adjustments to determine
if the module is functional.
C A U T I O N : The adjustments are extremely
delicate. Insert the screwdriver into the slots
V E R Y C A R E F U L L Y . Do not push hard or turn
hard against the stops. The arms have a
maximum turning angle of 270 degrees (three-
quarter turn).
Verify if the cruise control module is defective by
using the indicated settings:
Centering Adjustment
Turn the centering adjustment to the 10 o'clock
position (A).
Low Speed Switch Adjustment
Turn the low speed switch adjustment to the
10 o'clock position (B).
Sensitivity Adjustment
Turn the sensitivity adjustment full clockwise
(C).
NOTE: The adjustments may not be precisely
correct for the vehicle, but are acceptable to
determine if the module is functioning. The need
for more p r e c i s e a d j u s t m e n t s c a n be
determined by a road test.

If the adjustments have no effect on the cruise
control operation, replace the cruise control
module.
NOTE: The cruise control module is the only
component of the system that cannot be isolated
and tested separately. It must be tested while
connected to the other components of the
system.
