INSTALL a new auto-dimming interior mirror. REFER to Mirrors. ADJUST the zone setting. REFER to Compass Zone Adjustment See:
Adjustments/Compass Zone Adjustment. CALIBRATE the compass. REFER to Compass Calibration See: Adjustments/Compass Calibration. TEST the
system for normal operation.
No
GO to A19.
-------------------------------------------------
A19 CHECK FOR CORRECT IPC OPERATION
-
Disconnect the IPC connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-

Pinpoint Test B: The Compass Is Inaccurate
NOTE: This procedure is only applicable to vehicles without navigation. For vehicles with navigation, there is no compass zone adjustment.
Normal Operation
The compass module (integral to the auto-dimming interior mirror) provides vehicle directional inputs over the communication circuits to the Instrument
Panel Cluster (IPC), which sends the compass information to the Front Display Interface Module (FDIM) (compass display) over the Medium Speed
Controller Area Network (MS-CAN). The FDIM displays the compass direction according to the information that has been provided by the compass
module to the IPC. The compass display may provide inaccurate readings only if there is a concern with the compass module or the compass zone setting
is incorrect or the compass is out of calibration.
This pinpoint test is intended to diagnose the following:
-
Compass zone setting
-
Compass calibration
-
Compass module (integral to the auto-dimming interior mirror)
PINPOINT TEST B: THE COMPASS IS INACCURATE
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Always set the zone and calibrate the compass before replacing an inaccurate compass.
