Would this same method be used to read codes on an 02 ? I tried , no luck !

Default RE: Check engine light comes on at 40 mph and stays on

no, you have to get your codes from the blinkers and a electronic diagnosis manual.




1. Remove right side saddlebag and side cover if so equipped. Remove protective plug from data link connector. Other models will be under the seat.

2. To activate the diagnostic feature,follow these steps.
a. Create diagnostic test wire or use a female spade clip which will bridge the two terminals perfectly.
b. Install diagnostic test wire/clip across Terminals 1 and 2 on the data link connector, they are marked.
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.

IMPORTANT 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 not going to know what they mean.

1 Current 53 ECM flash error
2 Historic 53 ECM flash error
3 Current 54 ECM EEPROM error

10 Current 14 Loss of all ECM serial data (state of health)10 24 Loss of vehicle speed10 33 Loss of vehicle inhibit motion10 43 Loss of powertrain security status
11 Current 33 System relay contacts open
12 Current 33 System relay coil high/shorted

14 Current 33 System relay contacts closed
15 Current 99 Incorrect password

Thank you , did I read this part correctly ~ ~ IMPORTANT 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.

I think it should say "will not" but on my 07 fxst the engine "will" start when in diagnostic mode. But the diagnostic mode is different than yours. I suppose you could try it and find out just make sure your in neutral.

Default RE: Check engine light comes on at 40 mph and stays on

My engine light now stays on all of the time. I tried rjrivero's method on my 02 Roak King EFI and this is what my speedo read:
d01CLr

Each time in pushed in the trip it would progress all the way through to:
d10CLr

The next time I pushed in the trip it read:
PPV

Pushed the trip in one more time and it read:
82883

Pushed the trip in and the cycle repeated.

I'm confused?

Thanks!
