WORK FLOW

NOTE:
^ 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 will display "PAST NO RESPONSE".) Therefore, afier reconnecting the LCU connectors, erase the memory.
^ To erase the memory, perform the procedure below.
Erase the memory with CONSULT (Refer to EL-207.) or turn the ignition switch to "OFF" position and remove 7.5 A fuse [No. [14], located in the fuse block (J/B)].
