Pinpoint Test A: The Compass Is Inoperative
Refer to Wiring Diagram Set 124 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Power Mirrors for schematic and connector information. See:
Diagrams/Electrical Diagrams/Diagrams By Number
NOTE: This procedure is only applicable to vehicles without navigation. For vehicles with navigation, refer to Accessories and Optional Equipment.
Normal Operation
The compass module (integral to the auto-dimming interior mirror) provides vehicle directional inputs over the compass communication circuits to the
Instrument Panel Cluster (IPC), which sends the compass information to the FDIM over the Medium Speed Controller Area Network (MS-CAN). The
FDIM displays the compass direction according to the information that has been provided by the compass module to the IPC.
-
DTC U0161:00 (Lost Communication With Compass Module: No Sub Type Information) - sets when the IPC does not receive any
communication from the compass module for 5 seconds or longer.
-
DTC U0462:68 (Invalid Data Received From Compass Module: Event Information) - sets when the IPC attempts a self-test of the compass
module and its associated circuits and a failure results.
This pinpoint test is intended to diagnose the following:
-
Fuse(s)
-
Wiring, terminals or connectors
-
Compass module (integral to the auto-dimming interior mirror)
-
FDIM (compass display)
-
IPC
PINPOINT TEST A: THE COMPASS IS INOPERATIVE
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Always set the zone and calibrate the compass before replacing an inaccurate compass module.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
A1 CHECK THE COMPASS DISPLAY
-
Ignition ON.
-
Check the compass display in the upper right corner of the FDIM.
-
Does the compass display illuminate?
Yes
If the compass display illuminates with only 2 bars, GO to A2.
If the compass display turns on, but it does not display all directions, or indicates CAL, GO to Pinpoint Test B. See: Pinpoint Test B: The Compass Is
Inaccurate
No
