Eliminating the Sidestand switch on CAN-based models

This is done as a precaution or as a temporary fix, because of a malfunctioning sidestand switch.

On CAN-bus based models GS-911 will show you the status of the sidestand. The sidestand switch consists of two switches, named “Sidestand switch 1” and “Sidestand switch 2”. Using the values of these switch positions, the BMS-K then calculates the “Sidestand switch calculated”.

When looking at these values, they should all read the same – all should be either “extended” or “retracted”… A faulty (or unplugged) sidestand switch will typically show something like:

Sidestand 1 : extended
Sidestand 2 : retracted
Sidestand switch calculated : extended

As you can see the values for 1 and 2 differ and the calculated value is “Extended”, i.e. the BMS-K thinks the sidestand is extended and hence will disable the starting function…

The sidestand switch looks as follows:

Wires are typically, red, white and brown.

To eliminate the sidestand switch you have to short the outer most wires on the connector that connects to the harness. In this case these are white and brown (note that the wire are NOT in the same order on the connector on the switch itself!) – see below.

(Note the sequence of the wires differs on the connectors)

If you were performing the operation on the connector closest to the switch (sometime more practical for a fast fix in the field), it would look as follows:

Note: above the White and Brown wires are shorted. This will result in the ECU reading the switch as “retracted”. Reading the sidestand values with GS-911 will show the following:

Sidestand 1 : retracted
Sidestand 2 : retracted
Sidestand switch calculated : retracted
