Hi All,

I have a mate with an 07 Night Rod, he dont work with Computers much so i am asking this question on his behalf. Occasionally the check engine light comes on. He took it to a mechanic, who said he had an error code (he thinks it was # P0262?), and was told it related to High voltage somehow. The code was reset but appearede again at a later date. This time he fitted a new battery and it has been sometime , but it has just returned. He only rides occasionally, and Harley Mechanic not in our town. 

If anyone can provide some guidance it would be appreciated. I was thinking maybe Voltage Reg but only guessing. Feedback appreciated

 

PO262 is Front Injector High. I think it is the voltage that the injector is putting out which means it is running rich.

The IM (instrument module) is capable of displaying DTC's (diagnostic trouble codes).
Speedometer Self Diagnostics: The speedometer is capable of displaying and clearing
speedometer, tachometer, TSM/TSSM and ICM/ECM Diagnostic Trouble Codes (DTC).
1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting
sould illuminate, speedometer needle should sweep its full range
and indicator lamps (battery, security, low fuel, check engine and cruise) should
illuminate. The word “diag” should then appear.
4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with
the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing
is the one you are going to check. To move from one letter (module)
to the next, you push the odometer reset button one time. (from P to S to SP to t and back
to P, etc.)
P = ECM/ICM (Electronic Control Module (EFI) / (Ignition Control Module, 'Carbureted')
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button
in for 5 seconds and release. If there are any DTC’s the code will be
displayed or the word “none” will appear if there are no DTC’s. Push the odometer reset
button again to view additional codes if they exist.
7 - Record the codes.
8 - If DTC’s are not to be cleared, Press and release the odometer reset button. Part
number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in
and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up.
Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it
down then recheck the DTC’s again by repeating steps 1 to 9.
If the code is current it will reappear.
9 – Press and release the odometer reset button to continue to the next module.
10 – Turn Ignition switch to OFF.

after reading this site i reckon he must have error code P0563 and not P0262.. Tks

Possibly Voltage Regulator. Put a Volt Meter on the bike and see what voltage he gets. It should say in the manual what voltage to expect at certain revs. Also check all connections and especially the ground wire fro the Regulator. Does you mate have a manual? If not I will have a look at home tonight as I think I may have that one and post the pages to use to check Volt Reg

Thanks for the feedback guy's. I have also donbe some surfing and when time allows will do the IM display diagnostic check. From what I can gather the DTC is being held but not current. Pretty sure he has amanual, but thanks for the offer of assistance with the pages. Will post once we find cause and share findings.

Tks
