Default Check Engine Light Question

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.

1 Current 53 ECM flash error
2 Historic 53 ECM flash error
3 Current 54 ECM EEPROM error
4 Historic 54 ECM EEPROM error
5 Current 63 ECM serial data low
6 Current 63 ECM serial data open/high
7 Current 63 TSSM serial data low
8 Current 63 TSSM serial data open/high
9 Current 61 Loss of TSM/TSSM serial data
10 Current 14 Loss of all ECM serial data (state of health)
10 24 Loss of vehicle speed
10 33 Loss of vehicle inhibit motion
10 43 Loss of power train security status
11 Current 33 System relay contacts open
12 Current 33 System relay coil high/shorted
13 Current 33 System relay coil open/low
14 Current 33 System relay contacts closed
15 Current 99 Incorrect password
16 Current 99 Missing password
17 Current 41 CKP sensor intermittent
18 Current 41 CKP sensor synch error
19 Current 11 TP sensor open/low
20 Current 11 TP sensor high
21 Current 12 MAP sensor open/low
22 Current 12 MAP sensor high
23 Current 14 ET sensor voltage low
24 Current 14 ET sensor open/high
25 Current 15 IAT sensor voltage low
26 Current 15 IAT sensor open/high
27 Current 24 Front ignition coil open/low
28 Current 25 Rear ignition coil open/low
29 Current 24 Front ignition coil high/shorted
30 Current 25 Rear ignition coil high/shorted
31 Current 24 Front cylinder combustion intermittent
32 Current 25 Rear cylinder combustion intermittent
33 Current 23 Front injector open/low
34 Current 32 Rear injector open/low
35 Current 23 Front inject

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.

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.
