Diagnosing/Resetting the Cruise-Control operations:
1. fully engage parking brake. Make sure brake peddle is released.
2. Begin static portion of self test by pressing and holding speed control off switch.
3. Turn ignition switch from off to run. The cruise indicator on the instrument cluster will flash once to indicate the speed control module has entered diagnostic mode.
If the cruise indicator does not flash repeat steps 1-3. If the cruise indicator still does not flash, diagnose the cruise indicator.
4. Release the off switch
5. The cruise indicator will flash when each switch is pressed. While performing self test. Press each switch in the order described while observing cruise indicator for a flash. Note any switch activations that does not cause a flash.
Within five seconds of turning the ignition switch to RUN:
Press the on switch.
Press the resume switch.
Press the coast switch.
Press the set/accel switch.
6. NOTE: the on switch must be pressed within five seconds after entering the diagnostics mode or the speed control module will return to normal operating state and self-test must be repeated.
