(3) Relays (CABIN Model)
Checking Connector Voltage
1. Measure the voltage with a voltmeter across the battery terminal
and chassis as table below.
2. If the voltage differs from the battery voltage, the wiring harness
or fuse is faulty.
NOTE
Q
• The defogger rear and side are option.

Functional Check
NOTE
Q
• The relays described here are used same ones so that these
are interchangeable.
1. Apply battery voltage across the terminals a and c , and check for
continuity across the terminals d and e .
2. If continuity is not established across terminals d and e , replace
it.
