Acura RL. Manual - part 739

6. Reconnect the connector to the right rear power window switch, and make these input tests at the 

connector. 



If any test indicates a problem, find and correct the cause, then recheck the system.  



If all the input tests prove OK, the right rear power window switch must be faulty; replace it 
(see PASSENGER'S POWER WINDOW SWITCH TEST/REPLACEMENT ) and go to 
step 7.

There should be battery voltage between the No. 6 (No. 1)* (+) and No. 5 (No. 2)* (-(terminals when 
the ignition switch is ON (II).

between No. 3 (PLSB) (+) and No. 5 (SGND) (-) terminals, then run the power window motor down 
or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show 
the average voltage between 0-5 V). 

Front passenger's power window motor/Left rear power window motor 

Connect an analog voltmeter between the No. 5 (PLSA) (+) and No. 2 (SGND) (-) terminals, and 
between No. 4 (PLSB) (+) and No. 2 (SGND) (-) terminals, then run the power window motor down 
or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show 
the average voltage between 0-5 V). 

Right rear power window motor 

Connect an analog voltmeter between the No. 2 (PLSA) (+) and No. 5 (SGND) (-) terminals, and 
between No. 3 (PLSB) (+) and No. 5 (SGND) (-) terminals, then run the power window motor down 
or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show 
the average voltage between 0-5 V). 

6. If the voltage is not as specified, do these input tests: 



Driver's MPCS unit input test (see DRIVER'S MPCS UNIT INPUT TEST ).  



Front passenger's MPCS unit input test (see FRONT PASSENGER'S MPCS UNIT INPUT 
TEST ).  



Left power window switch input test (see LEFT REAR POWER WINDOW SWITCH 
INPUT TEST ).  



Right power window switch input test (see RIGHT REAR POWER WINDOW SWITCH 
INPUT TEST ).  

7. If the input tests are OK, replace the power window motor.  

8. Reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL 

UNIT ).  

POWER WINDOW MASTER SWITCH REPLACEMENT 

1. Remove the driver's door armrest (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).  

2. Disconnect the 6P connector (A) from the power window master switch (B).
