Ford F150 Pickup. Instruction - part 28

If the ON switch is not depressed within five seconds after entering the diagnostics mode, the module 
times out and the procedure must be started over. 

The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence 
immediately after the indicator light goes out for the previous switch. 

3. A lamp flash with the last button (SET/ACCEL) indicates that the static test passed. If the lamp does not 

flash with the last button and there are no additional flashes of the lamp, the switch is defective. 

If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for 
trouble codes: 

{

2 flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped).  

{

3 flashes - deactivator switch is open or circuit defective.  

{

4 flashes - vehicle speed signal is out of range or circuit is defective  

4. Immediately (.25 second delay) after the static test, the speed control servo does a dynamic test by 

automatically actuating the throttle lever from 8 mm (0.315 in) to 12 mm (0.472 in) of travel from the idle 
position. During the dynamic throttle pull, observe throttle movement to witness any binding or sticking 
of the speed control cable and correct connection of speed control cable to throttle lever. Make sure the 
throttle returns to the idle position.  

5. Return the ignition switch to the OFF position and proceed to the Symptom Chart.

NOTE:

There will be a slight delay when the last button is pressed and the lamp 
flashes.
