WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical test
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified. Do not use a non-powered probe
type tester.
Instructions must be followed carefully,
otherwise personal injury may result.

You should be familiar with the tools listed under the
heading “Special Tool”. You should be able to measure
voltage and resistance. You should be familiar with
proper use of a scan tool such as Air Bag Driver /
Passenger Load Tool, Connector Test Adapter Kit and
the Digital Multimeter.
Special tool
(A): 09932–76010 Connector Test Adapter Kit
This must be used whenever a diagnostic procedure
requests checking or probing a terminal.
Using the appropriate adapter in the special tool will
ensure that no damage to the terminal will occur from the

Inspection
S7RS0B9506014
NOTE
• When cleaning rear end door window glass, use a dry cloth to wipe it along heat
wire (1) direction.
• When cleaning glass, do not use detergent or abrasive-containing glass cleaner.
• When measuring wire voltage, use a tester with positive probe (2) wrapped with a tin
foil (3) which should be held down on wire
by finger pressure.

Wire Damage Inspection
1) Start engine.
2) Turn on defogger switch.
3) Measure voltage at the center of each defogger wire (1), and check defogger wire condition according to
the following table.
If defogger wire open is found, go to next step.
Defogger wire voltage
4) Touch voltmeter negative (–) lead to defogger wire ground terminal end (1).
5) Touch voltmeter positive (+) lead with a foil strip to defogger wire power source terminal end (2), then
move it along wire to defogger wire ground terminal
end (1).
The place where voltmeter fluctuates from 10 – 12 V
to 0 – 1 V is where there is open.
If found defective, repair defogger wire referring to
“Rear End Door Window Defogger Wire Repair”.
