compass

[20journey11]

My compass gets out of sync about every 6 weeks or so. I have to recalibrate, then it seems to be ok for a while. I did find if I have the variance set at +8, it seems to stay calibrated longer. Anyone else have problems with this? Is there a TSB or anything on this?

20,

No TSB on this issue. You may have already done this but I'll post it in case you did not.

MANUAL COMPASS CALIBRATION

CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the Remote Compass Module (RCM) located under the left rear section of the roof panel. Do not place any electronic devices (cell phones, laptop computers, PDAs, portable DVD players, etc), on or near this section of the exterior roof panel as the RCM performance may be effected. Do not use magnetic tools when servicing the RCM.

<br clear="left"><br clear="left"> NOTE: Confirmation that the proper variance zone is programmed, is recommended whenever manual compass calibration is performed, (Refer to 08 - Electrical/8M - Message Systems/Message Center/MODULE, Compass - Standard Procedure) for the appropriate procedure. The electronic compass unit features a self-calibrating design, which simplifies the calibration procedure. This feature automatically updates the compass calibration while the vehicle is being driven. This allows the compass unit to compensate for small changes in the residual magnetism that the vehicle may acquire during normal use. If the compass readings appear to be erratic or the Electronic Vehicle Information Center (EVIC) displays “CAL”, perform the following manual calibration procedure. Also, any time EVIC service replacement components are installed, they must be calibrated using this procedure. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.

Calibrate the compass manually as follows:

<br clear="right"> 1. Start the engine but leave the vehicle in “PARK” . 2. Using the U-Connect Touch ™ screen, select SETTINGS either from the hard controls on the sides of the screen, or from the menu selections at the bottom of the screen, depending on model. 3. Scroll through the menu, and select CALIBRATE COMPASS. 4. Select ON , the “CAL” symbol will come on solid in the EVIC display next to the compass direction that is displayed. 5. Slowly drive the vehicle on a level surface away from large metal objects, and power lines. Drive the vehicle through two or morecomplete circles, not exceeding 8 km/h (5 mph). The “CAL” message will disappear from the display to indicate successful compass calibration.<a name="CHR3dec39b8f2fb10048867f05f16396f1b"> 6. Confirm that the correct direction is now indicated by the compass. 7. Press the BACK button to return to the main menu.<br clear="right"><br clear="right"><br clear="left"> NOTE: If the compass display indicates an inaccurate compass heading or the display is locked up, the RCM (if equipped) may be inoperative and require replacement.<br clear="left"> NOTE: If the “CAL” message remains in the display, either there is excessive magnetism near the compass, or the EVIC is inoperative. Attempt the calibration procedure at least one more time before performing EVIC diagnosis.<br clear="left"> NOTE: If the wrong direction is still indicated in the compass display, the area selected for calibration may be too close to a strong magnetic field. Repeat the manual calibration procedure in another location.
