CHECK IN

LISTEN TO CUSTOMER COMPLAINT

IVMS COMMUNICATION DIAGNOSIS (EL-291 or EL-297)
Do self-diagnostic results exist?

Yes

SYMPTOM
BASIS

Repair/Replace according to
the self-diagnostic results.
(EL-293)

Perform diagnostic procedure
according to the symptom chart
on the next page.

IVMS COMMUNICATION
DIAGNOSIS (EL-291 or
EL-297)

REPAIR/REPLACE

FINAL CHECK
Confirm that the malfunction is completely fixed by operating the
system.

CHECK OUT

NOTICE:

When LCU connectors are disconnected for more than 1 minute such as during trouble diagnoses,
the “disconnected” data will be memorized by the BCM. (While BCM memorizes the “disconnected”
data, IVMS communication diagnosis of CONSULT-II will display “PAST NO RESPONSE”.)
Therefore, after reconnecting the LCU connectors, erase the memory.

To erase the memory, perform the procedure below.
Erase the memory with CONSULT-II (Refer to EL-291.) or turn the ignition switch to “OFF” position
and remove 7.5A fuse [No.

located in the fuse block (J/B)].
