(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.
• Be sure to use the 5 terminal type relay for the engine stop
relay (2).
• Other relays can use both 4 terminal type relay and 5
terminal relay.
• The color of the relay are black or green, both 4 terminal
type relay and 5 terminal type relay.
• The defogger rear and side are option.
