STEP 7. Measure the voltage at defogger relay connector
D-216.
(1) Disconnect defogger relay connector D-216, and measure

the voltage at the junction block side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 1 and ground.

• The measured value should be approximately 12 volts

(battery positive voltage).

Q: Does the measured voltage correspond with this range?

YES : Go to Step 10.
NO : Go to Step 8.

STEP 8. Check defogger relay connector D-216 for
damage.

Q: Is defogger relay connector D-216 in good condition?

YES : Go to Step 9.
NO : Repair or replace the connector. Refer to GROUP

00E, Harness Connector Inspection

STEP 9. Check the wiring harness between defogger relay
connector D-216 (terminal 1) and ignition switch (IG2).

NOTE: Also check junction block connector D-208. If junction
block connector D-208 is damaged, repair or replace the con-
nector as described in GROUP 00E, Harness Connector
Inspection

P.00E-2

.

Q: Is the wiring harness between defogger relay connector

D-216 (terminal 1) and ignition switch in (IG2) good
condition?
YES : Check that the defogger system works normally.
NO : Repair the wiring harness. Check that the defogger

system works normally.
