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 39 (20A)
through circuit SBP39 (WH/RD). Ground for the FDIM is supplied through circuit GD134 (BK/VT). 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 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 communications 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 interior rear view 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 Radio, Stereo and Compact Disc.
-------------------------------------------------
A2 CHECK CIRCUIT CPL60 (BN/YE) FOR VOLTAGE
-
Ignition OFF.
-
Disconnect: Interior Rear View Mirror C911.
