Self-Diagnosis Device - Yamaha FZ8NA Service Manual

Self-diagnosis device

1. Error code display
This model is equipped with a self-diagnosis
device for various electrical circuits.
If a problem is detected in any of those circuits,
the engine trouble warning light will come on
and the display will indicate an error code.
The self-diagnosis device also detects prob-
lems in the immobilizer system circuits.
If a problem is detected in the immobilizer sys-
tem circuits, the immobilizer system indicator
light will flash and the display will indicate an
error code.
TIP
If the display indicates error code 52, this could
be caused by transponder interference. If this
error code appears, try the following.
1. Use the code re-registering key to start the
engine.
TIP
Make sure there are no other immobilizer 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
interference, which may prevent the engine
from starting.
2. If the engine starts, turn it off and try start-
ing 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 standard
keys re-registered.
If the display indicates any error codes, note
the code number, and then have a Yamaha
dealer check the vehicle.

If the display indicates an error code, the
