1. Precaution

Before 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.

Reassemble parts in reverse order of disassembly
procedure unless otherwise indicated.

Adjust parts to specifications contained in this
manual if so designated.

Connect connectors and hoses securely during
reassembly.

After reassembly, ensure functional parts operate
smoothly.
CAUTION:

Airbag system wiring harness is routed near the
electrical parts and switch.

All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuit.

Be careful not to damage Airbag system wiring har-
ness when servicing the ignition key cylinder.
