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 

P.00E-2

.

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.

NOTE: Also check intermediate connectors C-12, C-28 and 
D-19. If intermediate connector C-12, C-28 or D-19 is dam-
aged, repair or replace the damaged component(s) as 
described in GROUP 00E, Harness Connector Inspection

.

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.
