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”.
Rear End Door Window Defogger Wire RepairS7RS0B9506015
1) Use white gasoline for cleaning.
2) Apply masking tape (1) at both upper and lower sides of heat wire (2) to be repaired.
3) Apply commercially-available repair agent (3) with a fine-tip brush (4).
4) 2 to 3 minutes later, remove masking tapes (1).
5) Leave repaired heat wire as it is for at least 24 hours before operating the defogger again.

Diagnostic Information and Procedures
BCM Self-Diagnosis FunctionS7RS0BA204001
• BCM monitors conditions of the system components and its circuit with ignition switch turned to ON position. When
an abnormality in the system oc curs, the area where that abnormality lies is stored in the memory of EEPROM in
BCM.
• DTC can be checked in either one of following ways. – DTC can be checked by SUZUKI scan tool (2) connected to DLC (1).
– DTC can be read from flashing pattern of theft deterrent light (3). Also, DTC is displayed on combination meter
(4) at the same time.
