Work Flow

Fig 1: Warning Chime Trouble Diagnoses Work Flow Diagram

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-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 CONSULT-II or turn the ignition switch to "OFF" position and remove 7.5A fuse [No. [14] located in the fuse block (J/B)].
