I have used a jumper cable connecting the pins in locations 1 and 2. If this diagnostics process is accurate my bike has the trouble code 21 inter active muffler control. Has anybody encountered this problem before and if so how was it solved?

yes thats it but the cable will not set the code unless it stops the servo motor from turnning.a lot of people disconnect the cable when switching from the stock exhaust.most of the time its the servo thats bad.heres a diagram on how to make one or you can disable it with ecm spy
Just happened to me. The controller was not working.
Opened it up and found the gear had stripped. A very nice member sold me one and problem solved.
Test it by turning key to on position and open throttle the controller should rotate and open muffler valve.

My XB has the stock exhaust and the muffler side of the control cable was apparently disconnected by the previous owner. Does anyone think that if I connect the muffler side of the control this might eliminate the occasional engine light blinking?

Mine throws occasional code 21 bcuz my cable is disconnected.(D&D exhaust) dealership fix was to put tension on the cable with a zip tie which works until the bikes really hot and the zip tie stretches.
The cable is pulled taught on the air cleaner side. I plan on really digging into this tomorrow once my ST Machine Pig Spotters 2 come in. Is it strongly suggested that I go through and reconnect the cable to my muffler? In doing this will it promote better performance?

yeah. it changes the route through muffler the exhaust takes at different rpm and throttle ranges. with the valve closed it restricts the flow(ithnk thats how works ne way) but yeah by all means hook it up
