Refer to Wiring Diagram Set 124, Power Mirrors for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By Number
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).
The compass module (integral to the auto-dimming interior 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 displays the compass direction according to
the information that has been provided by the compass module to the IC.
-
DTC B2097 (Compass Module Failure) - a continuous memory DTC that sets when the IC attempts a self-test of the compass module and its
associated circuits and a failure results.
-
DTC U2013 (Compass Module is Not Responding) - a continuous memory DTC that sets when the IC does not receive any communication from
the compass module for 5 seconds or longer.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Compass module (integral to the auto-dimming interior mirror)
-
FDIM (compass display)
-
IC
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: 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.
-
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
REFER to Accessories and Optional Equipment.
-------------------------------------------------
A2 CHECK THE POWER CIRCUIT FOR VOLTAGE
