code.
NOTE:If the display indicates error code 52,
this could be caused by transponder in-
terference. If this error code appears,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 enginefrom 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
key and both standard keys to a
Yamaha dealer and have the stan-
dard keys re-registered.
