1. Engine trouble warning light "U"
2. Immobilizer system indicator light "
This model is equipped with a self-diagnosis
device for various electrical circuits.
If any of those circuits are defective, the engine
trouble warning light will start flashing.
Refer to "FUEL INJECTION SYSTEM" on page
7-16. This model is also equipped with a self-di-
agnosis device for the immobilizer system.
Turn the key to "ON". If any of the immobilizer
system circuits are defective, the immobilizer
system indicator light will flash, and it will indi-
cate an error code. Refer to "IMMOBILIZER
SYSTEM" on page 8-29. However, if the indi-
cator light slowly flashes five times, and then
quickly flashes two times repeatedly, this error
could be caused by signal interference. If this
occurs, try the following.
1. Use the code re-registering key to start the
engine.
NOTE:
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 in-
terference, 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, re-register the standard keys.
If the multifunction display indicates an error
code, note the code number, and then check
the vehicle. Refer to "IMMOBILIZER SYSTEM"
on page 8-29.
