On the SP2, look for a green 2-pole connector near the battery cover. That's the service connector.
For the SP1, I believe the connector is at the rear and is black. It too is a 2-pole connector.
Jumper the connector and switch the key on.
You should then see a series of blinks if a fault code is stored.
Short 1/2 second blinks are 1's, longer blinks are 10's.
For instance, 1 long followed by 2 short is a fault code 12.
Two long followed by 1 short is 21, and so on.
There may be a longer 1.2 second pause between sets of blinks for multiple faults stored.
One thing to be aware of, the ECM will store all fault codes over time unless cleared.
Therefore, if the bike had a fault years ago, and nobody cleared the stored fault, you could be getting a false reading.
It's best to clear the stored faults and what current faults the system is detecting.
To do this, refer to the service manual on clearing stored fault codes.
