Yesterday came home bike was running normal. Went to start it today for work and noticed my check engine light. So it comes on for 5 seconds like normal for the efi. Goes off for 5 seconds and then comes on for 10 seconds and then goes off. Took the jeep to work, came home and tried it again, same thing.
Has anyone every seen anything like this before? Thought I would ask before I take it to the indy or the dealer. Any thoughts.

 

according to the book, what you describe indicates a historical trouble code is stored, but there is not one active. clear the codes and you're probably good to go.

 

1. Remove protective plug from data link connector under the seat.

2. To activate the diagnostic feature, proceed as follows:
a. Create diagnostic test wire .
b. Install diagnostic test wire across Terminals 1 and 2 on the data link connector, there're numbered on the plug.
c. Turn Ignition/Light Key Switch to IGNITION and wait approximately 10 seconds (4 seconds lamp ON, 6 seconds lamp OFF) for check engine lamp to start flashing.

3. All trouble codes are sent out as a series of flashes. To retrieve the first digit of the trouble code simply observe the number of times the lamp flashes.
a. The lamp will then flash one or more times to indicate the first digit of the trouble code.

b. The length of time the lamp is illuminated and the length of time in which it is off are each about 0.5 second in duration.

4. The second digit follows:
a. Following the transmission of the first digit, there is a 1.2 second pause in which the lamp is off.
b. The lamp will then flash one or more times to indicate the second digit of the trouble code. Count the number of times the lamp flashes to retrieve the second digit.

5. If more than one trouble code is sent:
a. Following transmission of the second digit of the first code, there is a 3 second pause in which the lamp is off.
b. Once all codes have been sent, the data string is repeated. When you have recorded the same trouble code twice, it is an indication that the transmission has been restarted and that all trouble codes have been retrieved.

NOTE If diagnostic test wire is installed across Pins 1 and 2 on connector in lieu of a Scanalyzer, the ECM is placed in a diagnostic test mode and the engine will start. The test wire must be removed from the data connector and the ignition switch turned OFF or the check engine lamp will continue to flash codes. A historic trouble code resides in the memory of the ECM until the code is cleared by use of the Scanalyzer or a total of 50 trips has elapsed. A “trip� consists of a start and run cycle, the run cycle lasting at least 30 seconds. After the 50 trip retention period, the trouble code is automatically erased from memory (that is, assuming no subsequent faults of the same type are detected in that period). The numbers after the 'historic' or 'current' is the speedo code number, but without the electrical diagnostics manual you're peeing into the wind.

My 04 FLHPI does that everytime I start it. Always has. After it goes out the second time, it stays out, no problems.

 

yep. you threw a code sometime, and it is still stored in memory. usually it will clear itself after 50 or so starts, or you can do it manually.

 

Thank you for the information.
Glide: I hope you copy/paste that comment.

 

glide thanks for the info.
My 06EG did it for about a month back in July, but then stopped.

 

When my bike was new I had a similar problem where the engine light went off and on but it would stay on for a while. It kept increasing and I took it back to the dealer. They read the code and found a loose plug that was never connected properly during assembly. They fixed it in about 15 min at the dealer.

 

Nah, just something I threw together from memory
