Test Procedure
- 1. Front Driver's Door Panel - Remove
- 2. Driver's Power Window Motor - Test
Without Door Multiplex Control Unit
With Door Multiplex Control Unit
1. Test the motor in each direction by connecting 12 volt battery power and ground to the power window master switch connector (A) according to the table. When the motor stops running, disconnect 12 volt battery power immediately.
- If the motor does not run or fails to run smoothly, remove the driver's power window regulator , then go to step 2.
- If the motor runs smoothly, go to Hall IC Unit (Pulser) Test.
2. Test the driver's power window motor (A) by connecting 12 volt battery power and ground according to the table. When the motor stops running, disconnect 12 volt battery power immediately.
3. If the motor does not run or fails to run smoothly, the driver's power window motor is faulty; replace the driver's power window motor . If the motor runs smoothly, replace the wire harnesses. - 3. Hall IC Unit (Pulser) Test
Without Door Multiplex Control Unit
1. Do the power window master switch (A) input test terminals No. 19, No. 22, and No. 23 - Refer to: Power Window Master Switch Input Test (Without Door Multiplex Control Unit) Power Window Master Switch Input Test (With Door Multiplex Control Unit) .
MTR SVCC circuit
Power window master switch connector No. 19 Body ground MTR PLSA and MTR PLSB circuits
Power window master switch connector No. 22 Body ground No. 23 Body ground - If the input test is OK, replace the power window master switch .
- If the input test is not as specified, check the driver's door harness. If the harness is OK, the Hall IC Unit (Pulser) is faulty; replace the driver's power window motor .
With Door Multiplex Control Unit 1. Disconnect the driver's power window motor connector
2. Check for continuity between driver's power window motor connector terminal No. 4 and body ground. There should be continuity.
- If there is continuity, reconnect the motor connector, then go to step 3.
- If there is no continuity, check for an open or high resistance in the BLK wire or poor ground (G501).
3. Do the power window master switch (A) input test terminals No. 13, No. 17, and No. 19 - Refer to: Power Window Master Switch Input Test (Without Door Multiplex Control Unit) Power Window Master Switch Input Test (With Door Multiplex Control Unit) .
MTR SVCC circuit
Power window master switch connector No. 13 Body ground MTR PLSA and MTR PLSB circuits
Power window master switch connector No. 17 Body ground No. 19 Body ground - If the input test is OK, replace the power window master switch .
- If the input test is not as specified, check the driver's door harness. If the harness is OK, the Hall IC Unit (Pulser) is faulty; replace the driver's power window motor .
- 4. All Removed Parts - Install - Install the parts in the reverse order of removal.
