Hall IC Unit (Pulser) Test

5. Measure the voltage between the terminals.

Common

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





Driver's power window motor

Connect an analog voltmeter between terminals No. 2 (PLSA) (+) and No. 5 (SGND) (-), and between terminals No. 3 (PLSB) (+) and No. 5 (SGND) (-), 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 terminals No. 5 (PLSA) (+) and No. 2 (SGND) (-), and between terminals No. 4 (PLSB) (+) and No. 2 (SGND) (-), 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 terminals No. 2 (PLSA) (+) and No. 5 (SGND) (-), and between terminals No. 3 (PLSB) (+) and No. 5 (SGND) (-), 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 Power Windows (Drivers MPCS Unit) Input Test/Replacement.
- Front passenger's MPCS unit input test Power Windows (Front Passengers MPCS Unit) Input Test/Replacement.
- Left power window switch input test Left Rear Power Window Switch Input Test.
- Right power window switch input test 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 Testing and Inspection.
