STEP 18. Check power window relay connector C-203 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.

Q: Is power window relay connector C-203 in good

condition?
YES : Go to Step 19.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. When the rear power window sub switch

(LH) is operated, the rear power window (LH) should
raise and lower normally.

STEP 19. Check the wiring harness between power
window relay connector C-203 (terminal 4) and rear power
window sub switch (LH) connector E-17 (terminal 6).

NOTE: Also check junction block connector C-215, intermedi-
ate connectors C-28 and D-19. If junction block connector
C-215, intermediate connector C-28 or D-19 is damaged, repair
or replace the connector as described in GROUP 00E, Harness
Connector Inspection

.

Q: Is the wiring harness between power window relay

connector C-203 (terminal 4) and rear power window
sub switch (LH) connector E-17 (terminal 6) in good
condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.

STEP 20. Check the ground circuit to the rear power
window sub switch (LH). Measure the resistance at rear
power window sub switch (LH) connector E-17.
(1) Disconnect rear power window sub switch (LH) connector

E-17 and measure the resistance available at the wiring
harness side of the connector.

(2) Measure the resistance value between terminal 5 and

ground, and also between terminal 8 and ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 22.
NO : Go to Step 21.

Q: Is the wiring harness between power window main

switch connector E-04 (terminals 1 and 3) and rear
power window sub switch (LH) connector E-17
(terminals 8 and 5) in good condition?
YES : Replace the power window main switch. When the

rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.

STEP 22. Check the wiring harness between rear power
window sub switch (LH) connector E-17 (terminals 4 and 7)
and rear power window regulator motor (LH) connector
E-16 (terminals 1 and 2).
Q: Is the wiring harness between rear power window sub

switch (LH) connector E-17 (terminals 4 and 7) and rear
power window regulator motor (LH) connector E-16
(terminals 1 and 2) in good condition?
YES : Replace the power window main switch. When the

rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.
