The forward facing sensor detects ambient light. This is to determine day or night time. This sensor will dim the mirror during night driving.
NOTE: The forward sensor dims in proportion to how dark it is. If the forward sensor is covered entirely, the mirror defaults to its darkest setting.
The rear facing sensor detects light coming from vehicle headlights from behind. The rear facing sensor is used to darken the mirror further when headlights are detected.

Compass Zone Selection:
NOTE: There are 2- different types of mirror setting controls the first type is done by pressing and holding an external switch, the other type is done using a paperclip to press an internal switch.
Press the switch on the right side of the mirror until ZONE is displayed.
Now press and release the switch on the right side of the mirror until the correct zone for your region is displayed (1 through 15). Use the map below to select the correct zone.
NOTE: This setting must be adjusted every time a customer passes through 3 zones.
Compass Calibration
Find a large open area with no overhead power lines or large metallic structures or objects.
NOTE: The area must be large enough to drive the vehicle in a circle several times.
Press and hold the switch on the left side of the mirror until CAL appears.
Drive the vehicle slowly in a circle until the word CAL disappears from the display, approximately two to four complete circles in the same direction.
NOTE: This calibration is necessary when the mirror with compass is initially installed in a vehicle and when a vehicle travels through 3 or more zones.
CAUTION: Magnets and large metal structures can interfere with the operation and accuracy of the compass.

|
YES NO |
Repair the open circuit Go to E5 |
|
E5: Use a DVOM, inspect continuity between Pin B (Black) at the temperature sensor and Pin 6 or 7 (Black)-(varies depending on initial assembly, wires are not polarity specific, verify wire color)

TEST STEP |
RESULT |
ACTION |
|
F1: Ignition On. Temperature reading switched on. Unplug temperature sensor. (NOTE: Due to the temperature display smoothing feature, you may have to wait at least 30-seconds for the temperature display to change after the sensor is disconnected). Did the display change from SC to OC? |
YES NO |
Replace the temperature sensor. Go to F2 |
|
F2: Ignition off. Disconnect the 7-pin connector from the mirror head. Measure continuity between pin A (Black/Green) and pin B (Black) of the temperature sensor connector.
|
YES NO |

|
F3: Disconnect the negative battery cable. Measure continuity between pin A (Black/Green) of the temperature sensor connector and ground. Is there continuity? |
YES NO |
Repair the short to ground in the temperature sensor harness. Go to F4 |
|
F5: Inspect for damaged pin terminals at the sensor and the mirror assembly. Was a problem found? |
YES NO |
Repair the terminals. Replace the mirror head |
The temperature sensor is mounted in front of the bumper area. Due to its location, the sensor can be affected by road or engine heat during idling or slow driving. Adaptation to ambient temperature takes place in steps through time filtering and depends on the prevailing driving conditions and amount of temperature change. Because of the filtering, the display will take up to 3 minutes to update to ambient temperature if the current ambient temperature is higher than the previous time the vehicle was turned on.
NOTE: Place the temperature sensor in a cup of Ice water or heated water to check its range of operation and compare it to an analog thermometer.
CAUTION: The outside temperature indicator is not designed to serve as an ice warning device and is not suitable for that purpose. Indicated temperatures just above freezing do not guarantee that the road surface is free of ice.
