Cruise Headache!!!
Hey Guys 2009 UC, Crusie control RESUME and ACCEL does not work however everything else does The SET and the DECL with the switch. Took it to my Dealer all seems to work will with no codes. I am so frustrated it also disengages properly with all functions brakes , clutch etc...anyone have the same issue?

I'd probably start by making sure the pin for that wire in the plug in the fairing is making contact with it's counterpart in the other half of the plug. Maybe check the continuity on the wire from the switch to its end, wherever that is. Finally if one of that works but the every other switch works, well then maybe the switch took a dump and needs to be replaced. Look on like eBay, should be a fairly easy replacement.

This is taken from the 2011 Touring Electrical Diagnostic Manual. I don't know if you can test it without a Breakout Box.
DTC P0577
PART NUMBER TOOL NAME
HD-48637 BREAKOUT BOX
Table 5-7. DTC P0577 Diagnostic Faults
POSSIBLE CAUSES
Short to voltage in cruise set/coast circuit
Cruise resume/accelerate switch malfunction
Cruise set/coast switch malfunction
Short to voltage in cruise resume/accelerate circuit
1. Cruise Set/Coast Circuit Voltage Test
1. Connect BREAKOUT BOX (Part No. HD-48637) between
wire harness [78B] and ECM [78A]. See 1.2 DIAGNOSTIC
TOOLS.
2. Turn IGN ON.
3. Using a multimeter, measure voltage between breakout
box terminal 22 and ground.
4. Is voltage greater than 1.0V?
a. Yes. Go to Test 2.
b. No. Go to Test 3.
2. Cruise Set/Coast Switch Test
1. Disconnect right hand controls [22].
2. Measure voltage between breakout box terminal 22 and
ground.
3. Is voltage greater than 1.0V?
a. Yes. Repair short to voltage on (BE/BK) wire. (5041)
b. No. Replace Cruise Set/Coast Switch. See the service
manual.
3. Cruise Resume/Accelerate Circuit Voltage
Test
1. Measure voltage between breakout box terminal 34 and
ground.
2. Is voltage greater than 1.0V?
a. Yes. Go to Test 4.
b. No. See diagnostic tips.
4. Cruise Circuit Voltage Test
1. Disconnect right hand controls [22].
2. Measure voltage between breakout box terminal 34 and
ground.
3. Is voltage greater than 1.0V?
a. Yes. Repair short to voltage on (W/BE) wire. (5041)
b. No. Replace Cruise Resume/Accelerate Switch. See
the service manual.
