Visual Inspection and Pre-checks
- Inspect the suspect exterior mirror for damage or obstructions.
NOTICE:
Use the correct probe adapter(s) when making
measurements. Failure to use the correct probe adapter(s) may cause
damage to the connector. Use only Rotunda Flex Probes (NUD105-R025D)
|
A1 CHECK THE MIRROR MOVEMENT |
-
Operate the suspect exterior mirror in the up, down, left and right directions.
Does the suspect exterior mirror operate in any direction?
|
A2 CHECK THE EXTERIOR MIRROR CONTROL SWITCH PARAMETER IDENTIFICATIONS (PIDS) |
-
Using a diagnostic scan tool, view the DDM Parameter Identifications (PIDs).

INSTALL a new LH front door window control switch. REFER to: Driver Door Window Control Switch (501-11 Glass, Frames and Mechanisms, Removal and Installation).
|
|
A3 CHECK THE VOLTAGE OUTPUT TO THE SUSPECT EXTERIOR MIRROR |
NOTICE:
The following step uses a test lamp to simulate
normal circuit loads. Use only a Rotunda Test Lamp (SGT27000) or
250-300mA incandescent bulb test lamp. To avoid connector terminal
damage, use the Rotunda Flex Probe kit for the test lamp probe
connection to the vehicle. Do not use the test lamp probe directly on
any connector.

concern may have been caused by module connections. ADDRESS the root
cause of any connector or pin issues.
|
|
NOTE:
The DDM and PDM automatically deactivate the heated exterior mirrors when the ambient air temperature is above 30° C (86° F).
![](images/diagnosis_and_testing_rear_view_mirrors-3233/2296/CaretRight_007(3).jpg)
PINPOINT TEST B: ONE OR BOTH HEATED EXTERIOR MIRRORS ARE INOPERATIVE OR ALWAYS ON (WITHOUT MEMORY MIRRORS)
NOTE:
Clean the entire mirror assembly and glass to assist
in verification of the customer concern and/or impact damage. Do not
clean any mirror glass or housing with an ice scraper, razor blade,
abrasive pad, harsh chemicals or petroleum based cleaning products, as
these may damage the mirror glass and/or housing.
