Is your turf mode working OK? There should another number under the '746', either 3, 4, or 5.I'm getting a code of 0-746. bike seems to run fine, just wondering what this code means. any help would be great, thanks
I have a 2016 570 EPS with turf mode, so I will use that as my point of reference. According to my manual and schematic, on the three-wire plug, pin A is 12 volts with ignition on, pin B goes to ECU (control) and Pin C goes to chassis ground.
When you put the switch in turf mode, the switch sends a signal to the ECU, and the ECU signals the solenoid driver to supply voltage to pin A of the two-wire plug. Pin B is solenoid ground.
You can test solenoid operation by supplying 12 volts to pin A while grounding pin B with the solenoid unplugged. The manual is very specific in stating that you must not supply voltage to the solenoid for more than one second. Presumably, the driver only supplies a short term voltage to the solenoid as well. If you remove the solenoid while making the test, you will see if the solenoid plunger is actuating.
If you have constant voltage at the two-pin plug, I would suspect the solenoid driver.
That's about all I know or can glean from the manual.
Let me make a correction... Top pic shows ground side of solenoid with switch off, regardless of gear lever position.Had a look at the solenoid driver circuit with an automotive scope this evening.
Here is what it looks like with ignition on and the gearshift in park or neutral.
Notice that the voltage is a straight line (at about 12 volts) with the solenoid disengaged. (measured on the ground side)

Here it is with the gearshift lever in reverse, low or high and the solenoid engaged.
Each line on the left is five volts, and the time is set at 5 milliseconds (.005 sec.)
You can see that the voltage runs from zero to about 12 volts. That's why you would see about 1/2 that with a digital volt meter.

I may have to do a bit more looking into each of the sensors and actuators "just for fun".
