CONSULT DIAGNOSTIC TEST MODE FUNCTION
CONSULT DIAGNOSTIC TEST
MODEDescription
C/U INITIALIZATION When replacing any of the following three components, C/U initialization is necessary.
[NATS ignition key/IMMU/ECM]
SELF-FUNCTION CHECK ECM checks its own NATS communication interface by itself.
SELF-DIAGNOSTIC RESULTS Detected items (screen terms) are as shown in the chart below.
NOTE:
When any initialisation is performed, all ID previously registered will be erased. So all NATS ignition
keys must be registered again.
The engine cannot be started with an unregistered key. In this case, the system may show ``DIFFER-
ENCE OF KEY'' or ``LOCK MODE'' as a self-diagnostic result on the CONSULT screen.
HOW TO READ SELF-DIAGNOSTIC RESULTS
* If trip number is more than 1, MIL does not blink.

carried out two or more times consecutively with the ignition key, IMMU
or ECM malfunctioning, NATS will shift the mode to one which prevents
the engine from being started.EL-268

PERFORM INITIALISATION.
Perform initialisation with CONSULT.
Re-register all NATS ignition key IDs.
For the initialisation procedure, refer to
``CONSULT operation manual NATS
V2.0''.
Can the system be initialized?
Note: If the initialisation is not completed
or fails, CONSULT shows

1. Replace IMMU.
2. Perform initialisation
