6. Reconnect the connectors to the under-dash fuse/relay box, and do these input tests at the following connectors.
 If any test indicates a problem, find and correct the cause, then recheck the system.
 If all the input tests prove OK, the MICU must be faulty; replace the under-dash fuse/relay box.

1. Remove the door panel (see page 20-7).
2. Disconnect the 6P connector from the driver’s power window motor.
3. Test the motor in each direction by connecting battery power and ground according to the table.
When the motor stops running, disconnect one
lead immediately.
4. If the motor does not run or fails to run smoothly, replace it. 5. Reconnect the 6P connector to the driver’s power
window motor.
6. Turn the ignition switch to ON (II).
7. Measure the voltage between the terminals.  There should be battery voltage betweenterminals No. 6 ( ) and No. 5 ( ).
 Connect an analog voltmeter between terminals No. 3 ( ) and No. 5 ( ), and run the power
window motor down or up. The voltmeter needle
should move back and forth alternately between
0 V and about 5 V (a digital voltmeter reads about
2.5 V).
 Connect an analog voltmeter between terminals No. 2 ( ) and No. 5 ( ), and run the power
window motor down or up. The voltmeter needle
should move back and forth alternately between
0 V and about 5 V (a digital voltmeter reads about
2.5 V).
8. If the voltage is not as specified, do the power window master switch input test at the appropriate
terminals:No.5,6,7,and16(seepage22-214).
9. If the switch is OK, replace the power window motor.
10. Reset the power window control unit (see page 22-210).

NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-93).
1. Clear the DTCs with the HDS.
2. Turn the ignition switch to LOCK (0), and then back to ON (II).
3. Turn the wiper switch to LOW or HIGH for 15 seconds or more, then turn the switch OFF.
Go to step 4.
Go to step 12.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure. The windshield wiper
system is OK at this time. Check for loose or poor
connections.
5. Turn the ignition switch to LOCK (0).
6. Do the wiper motor test (see page 22-231).
Go to step 7.
Replace the windshield wiper motor
(see page 22-233) and recheck.
7. Disconnect under-dash fuse/relay box connector F (34P) and windshield wiper motor 5P connector. 8. Check for continuity between windshield wiper
motor 5P connector terminal No. 5 and under-dash
fuse/relay box connector F (34P) terminal No. 32.
Go to step 9.
Repair an open in the WHT wire.
9. Check for continuity between windshield wiper motor 5P connector terminal No. 5 and body
ground.
Repair a short in the WHT wire.
Go to step 10.
