Wire Damage Inspection
- Turn ignition switch to ON position.
- Turn on defogger switch.
- Measure voltage at each position(s) as follows.
For wagon model:
Measure voltage at the center of each defogger wire (1), and check defogger wire condition according to the following table.
For sedan model:
Measure voltage at position "a" and position "b" 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 for wagon model
VOLTAGE CIRCUIT REFERENCEVoltage Circuit 10 - 12 V Defogger wire open between its center and defogger wire power source terminal end (2) 4 - 6 V Normal condition 0 - 1 V Defogger wire open between its center and defogger wire ground terminal end (3) Defogger wire voltage for sedan model
VOLTAGE CIRCUIT REFERENCEMeasuring position Voltage Circuit "a" 10 - 12 V Defogger wire open between defogger wire power source terminal end (2) and position "a" 7 - 9 V Normal condition 4 - 6 V Defogger wire open between position "a" and center line (4) "b" 4 - 6 V Defogger wire open between center line (4) and position "b" 2 - 4 V Normal condition 0 - 1 V Defogger wire open between position "b" and defogger wire ground terminal end (3) - Touch voltmeter negative (-) lead to defogger wire ground terminal end (1).
- 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).
For wagon model:
The place where voltmeter fluctuates from 10-12 V to 0-1 V is where there is open.
For sedan model:
The place where voltmeter fluctuates from 10-12 V to 4-6 V or 4-6 V to 0-1 V is where there is open.
If found defective, repair defogger wire referring to REAREND DOOR WINDOW / BACK WINDOW DEFOGGER WIRE REPAIR .
