• Before disassembling or reassembling parts, al-
ways disconnect the battery ground cable. When
repairing the audio, control module, etc. which are
provided with memory functions, record the memo-
ry contents before disconnecting the ground cable
from battery. Otherwise, these contents 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.
• All air bag system wiring harnesses and connec-
tors are yellow. Do not use the electrical test equip-
ment on these circuits.
• Be careful not to damage the airbag system wir-
ing harness when servicing the ignition key cylin-
der.
