Compass/Temp Module Does Not Calibrate

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. Perform the compass/temp module self-check. Turn the ignition off. Depress and hold the STEP button. Turn the ignition on and then release the STEP button. The compass/temp module will illuminate all of the VF segments and then display an "F" or "P". Exit the self-check by depressing the STEP button or cycling the ignition. If the compass/temp module displayed an "F" during the self-check, replace the compass/temp module. After replacing the compass/temp module, it must be calibrated to operate properly. If the compass/temp module did not display an "F" during the self-check, go to the next step.
    2. NOTE: Ensure that the vehicle has been properly demagnetized before attempting to calibrate the compass.
    CAUTION: The compass must be calibrated after any replacement or display "lock-up".
  2. Calibrate the compass using the following steps: Drive the vehicle to an area away from any large metal objects or overhead power lines. Ensure that the proper magnetic variance zone is stored in the compass memory. Turn the ignition on and ensure that the compass display is not blank. Depress and hold the STEP button for 5-10 seconds until ZONE appears in the display, then release the STEP button. The number displayed is the variance zone stored in the compass memory. To change the variance zone, depress the STEP button to scroll through the zone numbers 1-15 until the desired zone is displayed. After selecting the proper zone, wait approximately 15 seconds for the compass display to return to normal. With the engine running, depress and hold the STEP button for 5-10 seconds, ZONE will appear, then CAL. Release the STEP button within 2 seconds of CAL illuminating. With CAL displayed, drive slowly, less than 5 MPH (8 KPH) in 3 complete 360 degree circles. CAL will turn off and the compass will be calibrated. If the compass calibrated, the test is complete. If the compass did not calibrate, ensure that all calibration instructions have been followed carefully. Attempt to re-calibrate the compass, if unsuccessful, replace the compass/temp module.
