(6)  Engine ECU Power Relay, Glow Relay and Defogger Relay

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.

Functional Check

NOTE

• The relays described here are used same ones so that

these are interchangeable.

1. Apply battery voltage across the terminals 

c

 and 

d

, and check

for continuity across the terminals 

a

 and 

b

.

2. If  continuity  is  not  established  across  the  terminals 

a

  and 

b

,

replace it.
