Scan Tool References

Control Module References (See: Testing and Inspection/Programming and Relearning) for scan tool information.

Circuit/System Verification

Ignition ON, observe the scan tool Mirror Horizontal Position and Mirror Vertical Position parameters. The reading should be between 0.2-4.8 volts

and change as the mirror is moved, left, right, up, and down.

Circuit/System Testing

1. Ignition OFF, disconnect the X7 harness connector at the appropriate door module.

2. Ignition ON, verify a test lamp does not illuminate between the following circuit terminals and ground:

* 5-volt reference circuit terminal 7

* Signal circuit terminal 4

* Signal circuit terminal 5

* Low reference circuit terminal 10

瀚慖f the test lamp illuminates, test the appropriate circuit for a short to voltage.

3. Ignition OFF, test for infinite resistance between the following circuits and ground:

* 5-volt reference circuit terminal 7

* Signal circuit terminal 4

* Signal circuit terminal 5

* Low reference circuit terminal 10

瀚慖f less than the specified value, test the appropriate circuit for a short to ground.

4. Test for 4K-7K ohms between the 5-volt reference circuit terminal 7 and the low reference circuit terminal 10.

瀚慖f not within the specified range, test the 5-volt reference circuit and the low reference circuit for an open/high resistance. If the circuits

test normal, test or replace the rearview mirror.

5. Test for 1K-7K ohms between the 5-volt reference circuit terminal 7 and the signal circuit terminal 4.

瀚慖f not within the specified range, test the signal circuit for an open/high resistance. If the circuits test normal, test or replace the rearview

mirror.

6. Test for 1K-7K ohms between the 5-volt reference circuit terminal 7 and the signal circuit terminal 5.

瀚慖f not within the specified range, test the signal circuit for an open/high resistance. If the circuits test normal, test or replace the rearview

mirror.

7. If all circuits test normal, replace the door module.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
