  1. Depress and hold the following buttons:
    2. • MODE
    • ENGLISH/METRIC
  2. With the buttons depressed, turn the ignition switch to the RUN position.
  3. Observe the display segments in order to determine if the segments light for 2 seconds and then turn off for 2 seconds.

Do all of the display segments light and then turn off as described?

Go to Step 3

Go to Driver Information Center (DIC) Display Blank, Mode Indicator Changes with Mode Button

3

The driver information center (DIC) automatically tests the internal circuitry. Observe the display in order to determine if the display shows PS for approximately 2 seconds.

Does the display show PS for approximately 2 seconds?

The following error codes may occur with the DIC. Determine if any of the following codes exist:

    • E1 - Compass Circuit Frequency Failure
    • E2 - Compass Circuit Voltage Failure
    • E3 - Compass Storage Device Failure
    • E4 - Vehicle Communication Failure

Are any of the listed error codes present?

Go to Step 6

Go to Driver Information System Check

6

Replace the compass remote sensor. Refer to Electronic Compass Module Replacement

Does the error persist?

The following error codes may occur with the DIC. Determine if any of the following codes exist:

    • E1 - Compass Circuit Frequency Failure
    • E2 - Compass Circuit Voltage Failure
    • E3 - Compass Storage Device Failure
    • E4 - Vehicle Communication Failure

Are any of the listed error codes present?

The DIC displays the north-south compensation value for approximately 2 seconds.

Does the temperature display show N and a number within the specified range?

0-15

Go to Step 9

Go to Step 12

9

The DIC displays the east-west compensation value for approximately 2 seconds.

Does the temperature display show E and a number within the specified range?

0-15

Go to Step 10

Go to Step 12

10

The following actions occur in the DIC for approximately 2 seconds:

    • The variation number shows in the temperature display area.
    • The VAR indicator lights.

Is the variation number within the specified range?

1-15

Go to Step 11

Go to Step 12

11
    • The Self Diagnostics routine is complete. The display goes through the normal prove out routine and returns to display status.
    • The north-south and east-west compensation values should be a value within the specified range. If one of the compensation values is far out of this range, the vehicle may be highly magnetic.
    • Refer to Electronic Compass Operation in order to set the variance.

Has the self-test completed all of the circuit diagnostic tests?
