How do i reset the compass on a 2006 dodge grand caravan


Hi Roger, I'm glad to help. Below is the procedure for resetting the compass on your vehicle.



COMPASS VARIATION ADJUSTMENT Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and true geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this problem occurs, the compass variance setting may need to be changed.
To set the compass variance:

1. Using the Variance Settings map, find your geographic location and note the zone number Figure 1.
22681.jpg Figure 1 - Variance Settings 2. Turn the ignition switch to the On position. If the compass/thermometer data is not currently being displayed, momentarily depress and release the C/T push button to reach the compass/thermometer display. 3. On Electronic Vehicle Information Center (EVIC) and Compass Mini-Trip Computer (CMTC) equipped vehicles depress the Reset push button and hold the button down until "VAR = XX" appears in the display. This takes about five seconds. On Compass Temperature Module (CT) equipped vehicles depress the C/T push button and US/M push button down until "VAR = XX" appears in the display. This takes about five seconds. 4. Release the push button(s). "VAR =XX " will remain in the display. "XX" equals the current variance zone setting. 5. On Electronic Vehicle Information Center (EVIC) and Compass Mini-Trip Computer (CMTC) equipped vehicles momentarily depress and release the STEP button to step through the zone numbers, until the zone number for your geographic location appears in the display. On Compass Temperature Module (CT) equipped vehicles depress the US/M push button to step through the zone numbers, until the zone number for your geographic location appears in the display. 6. On Electronic Vehicle Information Center (EVIC) and Compass Mini-Trip Computer (CMTC) equipped vehicles momentarily depress and release the RESET push button to enter the displayed zone number into the EVIC/CMTC module memory. On Compass Temperature Module (CT) equipped vehicles depress the C/T push button to enter the displayed zone number into the electronic module memory. 7. Confirm that the correct directions are now indicated by the compass.

2006 Expedition overhead compass reads "N" when heading "E". Wonder how to reset it so it indicates the direction accurately.


Yes. Wish I could tell you which button for sure, but to reprogram the Compass you hold one of the buttons and drive in a circle one or two times to reacquire your position.

The letter C is flasing in my dash board


The flashing "C" in the Instrument cluster if for the Compass. Here's the bulletine...

Subject: Compass Displays a Steady or Flashing "C" In Place Of Directional Heading
Models: 2008 Saturn VUE built on or after 11/09/2007
This PI was superseded to update Recommendation/Instructions. Please discard PIT4699.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern: The compass displays a steady or flashing "C" in place of directional heading.

To return to a normal heading display, press and hold the cluster stem for approximately 2 Seconds.

The displayed heading is not correct after driving for 30 seconds, use the following "Compass Calibration" routine.

Press cluster stem until the Season Odometer is displayed (Not Trip A or B).

Press and hold cluster Stem until the solid "C" is displayed. To the right of the "C" will be the "Zone". Refer to the variation zone map above for the correct setting. Turn the stem Right to increase, Left to decrease. It will take a few seconds for a change of zone to be updated in the display.

Once the Zone is correct, press the Stem to display the Flashing "C". Do not touch the Stem again until the direction is learned. Drive the vehicle in slow circles in an open area until you see a compass (oc tant) heading replace the flashing C.

Note: Vehicles built prior to 11/09/2007 were not built with a compass.

Recommendation/Instructions:
Engineering is aware of this condition and is in the process of root causing. It is known that the Remote Compass Module (RCM), Body Control Module (BCM) and Cluster hardware are not at fault, and these parts should not be replaced.

Reinforce with the PDI technicians that the Compass Zone and calibration is still required as part of PDI.

Hope helps (remember to rate and comment this answer).

Tp 30 keeps failing the calibration. Everything else seems to work fine. Tried numerous times using the instructions, doing the slow circles but each time it fails. I believe the internal flux gate compass...


I had the same issue.I opened up the TP30 to find that the wires from the compass to the circuit board had corroded and snapped.Trying to source a new compass unit now.Anyone know if they are the same as the new TP32?

I have 2002 Yukpn Denali XL. There is a OC code that appears in the rear view. What is the cause of this and how can I fix it?


The "OC" indicates your compass is "Out of Calibration". Below is the proceedure to recalibrate your compass.

Compass Calibration
The compass may need calibration if:
 After five seconds, the display does not show a
compass heading (N for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.
 The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, the letters CAL must be displayed
in the mirror compass windows. If CAL is not
displayed, push in the COMP button for approximately
eight seconds or until the letters CAL are displayed.
The compass can be calibrated in one of two ways:
 Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or
 drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.

Good luck.

Compass out of whack


You need to recalibrate the compass. The procedure is in your owners manual. Here are the basic steps.

First, you will need to verify that your compass zone is set to your current geographic location. Since I do not know where you are located, I cannot tell you the code. They are listed in the manual. (For example, So Cal is zone 5.)

Second, here is the compass calibration adjustment procedure:

Perform this adjustment in an open area free from steel structures and high voltage lines. For optimum calibration, turn off all electrical accessories (heater/air conditioning, wipers, etc.) and make sure all vehicle doors are shut.
1. Start the vehicle.
2. To enter the compass calibration mode, press and hold the button for greater than eight seconds. The display will then show CAL in the display window.
3. Drive the vehicle slowly (less than 3 mph) in circles until CAL indicator turns off. As many as 5 complete circles may be required.
4. The compass is now calibrated.

Compass calibration


Hello. First day I use this device, and have found this tips for compass calibration (as I understand, compass calibration depend on satellite signals - so before compass calibration it's better to get good signals from satellites):
- keep device at horizontal plane (as from message "hold level");
- turn it slow, but not too very slow.
It's better don't turn device, but get device at hands, and turn around himself with it with constant slow speed, and keep horizontal level of device - by this way I have a more accurate calibration, than turn just in hands or on the table.
I hope this will help.
