If any of the immobilizer system circuits
are defective, the immobilizer system
indicator light will flash, and then the
right display will indicate a two-digit er-
ror code.
NOTE:
If the right display indicates error code
52, this could be caused by transpon-
der interference. If this error code ap-
pears, try the following.
1. Use the code re-registering key to
start the engine.
NOTE:
Make sure there are no other immobi-
lizer keys close to the main switch, and
do not keep more than one immobilizer
key on the same key ring! Immobilizer
system keys may cause signal interfer-
ence, which may prevent the engine
from starting.
2. If the engine starts, turn it off and
try starting the engine with the
standard keys.
3. If one or both of the standard keys
do not start the engine, take the
vehicle, the code re-registering
INSTRUMENT AND CONTROL FUNCTIONS
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.
If the right display indicates any error
codes, note the code number, and then
have a Yamaha dealer check the vehi-
cle.
CAUTION:
If the display indicates an error
code, the vehicle should be checked
as soon as possible in order to avoid
engine damage.
