STEP 6. Check the front power window motor (RH).
(1) Remove the front power window regulator (RH). Refer to

Door Glass and Regulator

P.42A-124

.

(2) Connect a battery to the motor terminal, and check that the

motor runs freely.

Q: Is the front power window motor (RH) normal?

YES : Go to Step 7.
NO : Replace the front power window regulator (RH).

When the front power window sub switch (RH) is
operated, the front power window (RH) should raise
and lower normally.

STEP 7. Check the battery power supply circuit to the front
power window sub switch. Measure the voltage at front
power window sub switch connector E-09.
(1) Disconnect front power window sub switch connector E-09

and measure the voltage available at the wiring harness
side of the connector.

(2) Measure the voltage between terminal 6 and ground.

• The voltage should measure approximately 12 volts

(battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 10.
NO : Go to Step 8.

STEP 8. Check ETACS-ECU connector C-315 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is ETACS-ECU connector C-315 in good condition?

YES : Go to Step 9.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. When the front power window sub switch

(RH) is operated, the front power window (RH) should
raise and lower normally.

STEP 9. Check the wiring harness between ETACS-ECU
connector C-315 (terminal No. 8) and front power window
sub switch connector E-09 (terminal No. 6).
NOTE: Also check intermediate connector C-116. If intermedi-
ate connector C-116 is damaged, repair or replace the dam-
aged component(s) as described in GROUP 00E, Harness
Connector Inspection

P.00E-2

.

Q: Is the wiring harness between ETACS-ECU connector

C-315 (terminal No. 8) and front power window sub
switch connector E-09 (terminal No. 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
front power window sub switch is operated, the front
power window (RH) should raise and lower normally.

STEP 10. Check the ground circuit to the front power
window sub switch. Measure the resistance at front power
window sub switch connector E-09.
(1) Disconnect front power window sub switch connector E-09

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 12.
NO : Go to Step 11.

STEP 11. Check the wiring harness between power window
main switch connector E-15 (terminals Nos. 1 and 3) and
front power window sub switch connector E-09 (terminals
Nos. 8 and 5).
NOTE: Also check intermediate connectors C-116 and C-128.
If intermediate connector C-116 or C-128 is damaged, repair or
replace the damaged component(s) as described in GROUP
00E, Harness Connector Inspection

P.00E-2

.

Q: Is the wiring harness between power window main

switch connector E-15 (terminals Nos. 1 and 3) and front
power window sub switch connector E-09 (terminals
Nos. 8 and 5) in good condition?
YES : Replace the power window main switch. When the

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

STEP 12. Check the wiring harness between front power
window sub switch connector E-09 (terminals Nos. 4 and
7) and front power window motor (RH) connector E-10
(terminals Nos. 1 and 4).
Q: Is the wiring harness between front power window sub

switch connector E-09 (terminals Nos. 4 and 7) and front
power window motor (RH) connector E-10 (terminals
Nos. 1 and 4) 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
front power window sub switch (RH) is operated, the
front power window (RH) should raise and lower
normally.

STEP 13. Check rear power window sub switch (LH)
connector E-24 and rear power window motor (LH)
connector E-25 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Are rear power window sub switch (LH) connector E-24

and rear power window motor (LH) connector E-25 in
good condition?
YES : Go to Step 14.
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 14. Check the rear power window sub switch (LH) for
continuity.
(1) Remove the rear power window sub switch (LH). Refer to

Door Glass and Regulator

P.42A-124

.

(2) Check continuity when the rear power window sub switch

(LH) is operated to "UP" or "DOWN" position.

Q: Is the rear power window sub switch (LH) normal?

YES : Go to Step 15.
NO : Replace the rear power window sub switch (LH).

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