      REFER to: GLOBAL POSITIONING SYSTEM MODULE (GPSM) (Vehicles With: AM/FM/CD/SYNC) .

      REFER to: GLOBAL POSITIONING SYSTEM MODULE (GPSM) (Vehicles With: SYNC/Sony AM/FM/CD) .

      For vehicles equipped with the compass zone and calibration setting menu in the message center, GO to AX5

  5. AX5 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST 
    • Using a scan tool, perform the BCM self-test.

    Are any Diagnostic Trouble Codes (DTCs) recorded? 

    1. Yes:  REFER to: BODY CONTROL MODULE (BCM) .
    2. No:  INSTALL a new compass module.

      REFER to: Compass Module  .

      SET the compass zone and CALIBRATE the compass. REFER to the Owner's Literature TEST the system for normal operation. If the compass is still inoperative, GO to  AX11

  6. AX6 CHECK THE COMPASS MODULE VOLTAGE SUPPLY 
    • Ignition OFF.
    • Disconnect: Compass Module.
    • Ignition ON.
    • Measure:

    Click to display connectors

    Positive Lead Measurement / Action Negative Lead

    • Measure:

    Click to display connectors

    Positive Lead Measurement / Action Negative Lead
    C909-1
    G08065506
    		 C909-2

    Is the voltage greater than 11 volts? 

    1. Yes:  GO to AX8
    2. No:  REPAIR the circuit.
  8. AX8 CHECK THE COMPASS COMMUNICATION BUS FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: BCM C2280H.
    • Ignition ON.
    • Measure:

    Click to display connectors

    Positive Lead Measurement / Action Negative Lead
    C909-3
    G08065507
    		 -

    Is any voltage present? 

    1. Yes:  REPAIR the circuit.

  9. AX9 CHECK THE COMPASS COMMUNICATION BUS FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Measure:

    Click to display connectors

    Positive Lead Measurement / Action Negative Lead
    C909-3 Ω -

    Is the resistance greater than 10, 000 ohms? 

    1. Yes:  GO to AX10
    2. No:  REPAIR the circuit.
  10. AX10 CHECK THE COMPASS COMMUNICATION BUS FOR AN OPEN
