cuits.
If any of those circuits are defective, the
engine trouble warning light will come
on, and then the multi-function display
will indicate a two-digit error code (e.g.,
11, 12, 13).
If the multi-function display indicates
such an error code, note the code num-
ber, and then have a Yamaha dealer
check the vehicle.

If the display indicates an error
code, the vehicle should be checked
as soon as possible in order to avoidengine damage.
This model is also equipped with a self-
diagnosis device for the immobilizer
system.If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light will flash, and then the
multi-function display will indicate a
two-digit error code (e.g., 51, 52, 53)
when the key is turned to “ON”.
NOTE:If the multi-function display indicates er-
ror code 52, this could be caused by
transponder interference. If this errorappears, try the following.
1. Use the code re-registering key to
