NOTICE:
I
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.
I
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)].
