N. Check Engine Lamp Diagnostics
The S&S Cycle ECU has a feature which can report engine faults by ashing a code via the Check Engine lamp on the motorcycle.
NOTE: If you have set your motorcycle to use the check engine lamp as a shift-light, this function will be disabled.
The procedures to activate and read the check engine lamp are as follows:
1. Turn the ignition switch to the ON position for three seconds (one second pause after the fuel pump stops), and then switch back to the
OFF position for three seconds. Repeat this procedure one more time and then turn the ignition to the ON position and wait for eight
seconds for the check engine lamp to start ashing.
2. The transmission of a code is always preceded by a series of rapid ashes (about 3 per second). This “intermission” is followed by a 2 second
pause in which the lamp is o. The lamp will then ash one or more times to indicate the rst digit of the trouble code. The length of time
the lamp is illuminated and the length of time in which it is o are each about 1 second in duration. The number of times the lamp ashes
indicated the rst digit of the trouble code.
3. Following the transmission of the rst digit, there is another 2 second pause in which the lamp is o. The lamp will then ash one or more
times to indicate the second digit of the trouble code. The number of times the lamp ashes indicates the second digit of the trouble
code.
4. Following the transmission of the second digit, there is a third 2 second pause in which the lamp is o. After the pause comes an “intermission”,
followed by transmission of the next recorded trouble code. All subsequent codes are sent in the same manner, each separated from the
next by an “intermission”. Once all the trouble codes have been sent the data string is repeated. See section P for a list of the trouble codes
supported.
5. Turn the Ignition Key switch to OFF. Wait 10 seconds for the ECU relay to click. The vehicle can now be started normally.
