Engine code, engine light came on yesterday, wonder how to read em, how to figure out what they mean as cheaply as possible. It's a an 07,fuel injected, 96 cubic inch,

To pull the codes:
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 should 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
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.
1 - Record the codes.
2 - 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 3 If the code is current it will reappear.
4 - Press and release the odometer reset button to continue to the next module.
5 - Turn Ignition switch to OFF.
On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.
"No Rsp" will also appear if the run/off switch is in the off position when doing this procedure.
Once you get the codes, repost what you have.
Example - U1301

Got numbers b1121, u1016, what does this mean

You can buy the computer reader at advanced auto for 25.00 or you can undo battery for 5 minutes then hook back up and it will clear the code if it comes back on go to harley and they will check it for free and tell you whats wrong
