B: CAUTION
•Before disassembling or reassembling parts, al-
ways disconnect the battery ground cable from bat-
tery. When repairing the audio, control module, etc.
which are provided with memory functions, record
the memory contents before disconnecting the
ground cable from battery. Otherwise, these con-
tents are erased upon disconnection.
•Reassemble the parts in the reverse order of dis-
assembly unless otherwise indicated.
•Adjust the parts to the specifications described in
this manual if so designated.
•Connect the connectors securely during reas-
sembly.
•After reassembly, ensure the functional parts op-
erate smoothly.
•The air bag system wiring harness is routed near
electrical parts and switches.
•Airbag system wiring harnesses and connectors
are yellow. Do not use the electrical test equipment
on these circuits.
•Be careful not to damage the airbag system wir-
ing harness when servicing the ignition key cylin-
der.
