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.

DIFFERENCE OF KEYIMMU can receive the key ID signal but the result of ID veri®cation
between key ID and IMMU is NG.EL-264
CHAIN OF IMMU-KEY IMMU cannot receive the key ID signal. EL-265
ID DISCORD, IMM-ECMThe result of ID veri®cation between IMMU and ECM is NG. System ini-
tialisation is required.EL-266
MINGLE NOISENoise (interference) mingled into NATS communication lines during com-
municating.EL-267
DON'T ERASE BEFORE CHECK-
ING ENG DIAGEngine trouble data and NATS trouble data have been detected in ECM. EL-259
