Compass: Component Tests and General Diagnostics
Self-Diagnostic Test
The CMTC is capable of performing a diagnostic self check on many of its internal functions. CMTC diagnostics may be performed using a scan tool
(DRB) and the proper Body Diagnostic Procedures manual or by the following procedure.
1. With the ignition switch in the OFF position, press both the US/M and STEP button.
2. Turn ignition switch to the ON position.
The CMTC will perform internal checks while lighting all segments of the vacuum florescent display Upon completion of the internal check, the CMTC
will display:
-
PASS
-
FAIL
-
CCD
If any segment of the CMTC fails to light replace the module.
If FAIL is displayed, replace the module.
If CCD is displayed, check the CCD and Body Control Module (BCM) for proper operation, refer to the appropriate diagnostic test procedures. If the
CCD and the BCM are OK, replace the CMTC module.
For additional diagnostic information on the CMTC and for identifying CMTC problems, refer to the proper Body Diagnostic Procedures.

Variance Settings
VARIANCE SETTING PROCEDURE
Variance is the difference between magnetic North and geographic North. To adjust the compass variance set the CMTC to Compass/Temperature
mode and press both US/M and STEP buttons for up to one second than the symbol VAR and the current variance zone number will be displayed.
Press the STEP button to select the proper variance zone as shown. After five seconds of inactivity, the displayed zone will be automatically set
and normal operation in the Compass/Temperature mode resumed.
DIRECT METHOD
Turn the vehicle to head in either a North or South direction. The vehicle must be within 45 degrees of the North or South position or the
SETTING the VARIANCE will be ignored. The vehicle may be stationary or driving at any speed for this operation. Depress the STEP button
until the Compass/Temperature screen is displayed. Simultaneously press both the US/M and STEP buttons up to one second, than the symbol
VAR and the current variance zone number will be displayed. Within the next five seconds momentarily press the US/M button. The variance will
be set and normal operation in the Compass/Temperature mode resumed. If the US/M button is not pressed within the five seconds interval, the
compass variance shall not be changed and normal operation in the Compass/Temperature mode resumed. If the VAR symbol flashes twice before
resuming operation, the new zone was not accepted. Realign the vehicle to within ± 45 degrees of North or South and try again.
