I have a 2002 Road King Classic FLHRCI and my cruise control quit working. The indicator light comes on but it will not lock into a speed. any ideas on whats goin on?????

 

Check both brake light switches, and the clutch switch. If one is bad CC will not engage.

 

What he said. Have you changed the bars or messed with the brake side any?

 

Try unhooking one of the wires to the roll off switch.

 

This is what fixed(?) my 03 RK years ago. Took this wire off and now I shut it off with the brakes, clutch, or CC switch. Unplug it and take it for a spin and see what it does......

 

If you have EFI there's a cruise control diagnostics test you can run.

Ignition off, cruise switch on, hold cruise "set" button and turn ignition to "run", the "C" will illuminate as long as the switch is held.
Release set button, and push switch to "res" and the C will light up as long as the switch is held.
Release resume button, roll throttle forward to test roll off switch, C will illuminate as long as the throttle roll off switch is activated.
Release throttle, apply front brake and C will light as long as the brake is held.
Release front brake, press and hold the rear brake for at least 5 seconds. The C will light up for 5 seconds and then extinguish on it's own. Release brake pedal when light goes out and cruise module will slightly open throttle and release.

You can also do a cruise control drop out test

The last eight diagnostic codes for cruise disengagement are
stored in memory.
1. To enter the diagnostic mode, turn the engine off and
proceed as follows:
a. Turn the fairing cap Cruise ON/OFF switch to OFF.
The light in the rocker switch is extinguished to indicate
this condition to the operator.
b. Push the Cruise SET/RESUME Switch on the right
handlebar to SET and hold.
c. Turn the Ignition/Light Key Switch to IGNITION, but
do not start the engine.
d. Release the Cruise SET/RESUME Switch from the
SET position while observing the behavior of the
green Cruise Engaged Lamp (capital letter “C”) on
the tachometer gauge.
2. The system transmits the most recent cruise dropout
code. Each dropout code consists of 3 digits and is sent
out as a series of flashes.
3. The lamp will begin by flashing one or more times to indicate
the first digit of the dropout code. The length of time
the lamp is illuminated and the length of time in which it
is off are each about 1/4 second in duration. Simply
count the number of times the lamp flashes in order to
retrieve the first digit of the dropout code.
4. Following transmission of the first digit, there is a one
second pause in which the lamp is off. The lamp will then
flash one or more times to indicate the second digit of
the dropout code. Count the number of times the lamp
flashes to retrieve the second digit. See Figure 7-5.
5. Following transmission of the second digit, there is a
another one second pause in which the lamp is off. The
lamp will then flash one or more times to indicate the
third digit of the dropout code. Again, count the number
of times the lamp flashes to retrieve the third digit.
6. Write down the dropout code on a piece of paper. To
identify the reason for cruise disengagement see Table
7-3. The last column of the table suggests the appropriate
corrective action.
7. To verify the dropout code, toggle the Cruise SET/
RESUME Switch to RESUME. The transmission of the
most recent dropout code is repeated. To continue with
the next code, simply toggle the Cruise Switch to SET.
All subsequent codes are sent in the same manner as
the first, after which the operator may repeat the code or
move on to the next in the series.
8. After the eighth (or oldest) dropout code is flashed, the
Cruise Engaged Lamp remains illuminated to indicate
that the end of the dropout code buffer has been
reached.
9. To start the sequence at the beginning, that is, with
transmission of the most recent dropout code, momentarily
push the Cruise SET/RESUME Switch to SET.

 

Cruise control dropout codes

 

Great info, my 2007 Ultra is doing the same thing, I will check it out, thanks for the info.

 

My 06 ultra passed all the test. Green light came on like the cruise was working but it was not. It waa the cruise module. I found a used one on ebay & that fixed it.

 

Mine quit when I installed apes. I could not figure it out. All the tests seemed ok. I bought the electrical trouble shooting manual. Used that flow chart found my problem in just a few minutes. It was a bad connection in the headlight.
