1. Precaution
IBefore disassembling or reassembling parts,
always disconnect battery ground cable. When
repairing radio, control modules, etc. which are
provided with memory functions, record
memory contents before disconnecting battery
ground cable. Otherwise, these contents are
cancelled upon disconnection.
IReassemble parts in reverse order of disas-
sembly procedure unless otherwise indicated.
IAdjust parts to specifications contained in
this manual if so designated.
IConnect connectors and hoses securely dur-
ing reassembly.
IAfter reassembly, ensure functional parts
operate smoothly.
CAUTION:
IAirbag system wiring harness is routed near
the electrical parts and switch.
IAll Airbag system wiring harness and con-
nectors are colored yellow. Do not use electri-
cal test equipment on these circuits.
IBe careful not to damage Airbag system wir-
ing harness when servicing the ignition key
cylinder.
