Turn the ignition switch OFF.
Short the relay connector terminals of the wire har-
ness side with a jumper wire.
Remove the maintenance lid (page 3-4).
Disconnect the fuse 10 A.
Turn the ignition switch "ON".
Measure the voltage between the fuse box terminal
connector of the wire harness side and ground.
If the battery voltage appears, the main relay switch
line is normal.
Inspect the main relay function test (page 22-25).
If the battery voltage does not appear, inspect the
following:
– Open circuit in Red wire between the main fuse
and main relay switch line side
– Open circuit in Red/Yellow wire between the
main relay and fuse box
FUNCTION TEST
Remove the main relay (page 22-26).
Connect an ohmmeter to the switching side relay
terminals.
Connect a 12 V battery to the coil side relay termi-
nals.
There should be continuity while the battery is con-
nected to the relay terminals and there should be no
continuity when the battery is disconnected.
