Escape 2WD V6-3.0L (2009)
Adjustment. CALIBRATE the compass. REFER to Compass Calibration See: Adjustments/Compass Calibration. TEST the system for normal
operation.
No
GO to A8.
-------------------------------------------------
A8 CHECK FOR CORRECT IC OPERATION
-
Disconnect the IC connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the IC connector and make sure it seats correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new IC. RESET the parameters in both the IC and the PCM. REFER to Antitheft and Alarm Systems. PROGRAM the PATS keys into the
new IC. REFER to Antitheft and Alarm Systems. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the
ignition. REPEAT the self-test. TEST the system for normal operation.

Pinpoint Test B: The Compass Is Inaccurate
NOTE: This pinpoint test is for vehicles without navigation. For vehicles with navigation, refer to Radio, Stereo, and Compact Disc.
Normal Operation
The compass display (located in the Front Display Interface Module (FDIM)) receives battery voltage from the Smart Junction Box (SJB) fuse 14 (10A)
through circuit SBP14 (BN/RD). Ground for the compass display is supplied through circuit GD114 (BK/BU). The compass module (integral to the
interior rear view mirror) provides vehicle directional inputs to the Instrument Cluster (IC), which sends the compass information to the FDIM over the
Medium Speed Controller Area Network (MS-CAN). The FDIM will display the compass direction according to the information that has been provided
by the compass module to the IC.
This pinpoint test is intended to diagnose the following:
-
Magnetized vehicle
-
Compass zone setting
-
Compass calibration
-
Compass module
PINPOINT TEST B: THE COMPASS IS INACCURATE
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.

B1 DEMAGNETIZE THE VEHICLE
-
Demagnetize the vehicle. Refer to Vehicle Demagnetizing See: Adjustments/Vehicle Demagnetizing.
-
Does the compass operate correctly?
