Pinpoint Test M: Navigation Is Inoperative

Information and Entertainment System

Pinpoint Test M: Navigation Is Inoperative

Normal Operation

The Global Positioning System Module (GPSM) provides information from the GPS (Global Positioning System) satellite system to the Accessory Protocol Interface Module (APIM). This information is used to calculate vehicle position and direction of travel.

Removal of the navigation SD card results in loss of navigation while the card is removed. This is normal operation.

This pinpoint test is intended to diagnose the following:

- Navigation map SD card not present

- Network communication concern

- APIM (Accessory Protocol Interface Module)

- GPSM (Global Positioning System Module)

PINPOINT TEST M : THE NAVIGATION IS INOPERATIVE

M1 CHECK THE NAVIGATION SYSTEM OPERATION

- Verify the navigation system operation.

Does the audio system display "SD CARD FAULT"?

Yes
GO to M2.

No
GO to M3.

M2 VERIFY THE SD CARD WITH NAVIGATION MAP IS PRESENT

- Check for the presence of an SD card with map data in the SD slot of the media hub.

Is the navigation map SD card present?

Yes
GO to M3.

No
INSTALL the navigation map SD card. TEST the system for normal operation.

M3 RETRIEVE THE DTCs FROM THE APIM (Accessory Protocol Interface Module) AND GPSM (Global Positioning System Module) SELF-TESTS

- Check the APIM (Accessory Protocol Interface Module) and GPSM (Global Positioning System Module) DTCs from the continuous self-test.

Are any DTCs present?

Yes
If DTC B1215:00 is present, GO to Pinpoint Test H Pinpoint Test H: The Media Hub Is Inoperative Or Has Poor Sound Or Image Quality.

For all others, REFER to DTC Charts Accessories and Optional Equipment.

No
GO to M4.

M4 CHECK FOR SCAN TOOL COMMUNICATION WITH THE GPSM (Global Positioning System Module)

- Ignition ON.

- Carry out the network test using the scan tool.

Does the scan tool communicate with the GPSM (Global Positioning System Module)?

Yes
GO to M5.

No
REFER to Information Bus.

M5 CHECK FOR CORRECT GPSM (Global Positioning System Module) OPERATION

- Disconnect the GPSM (Global Positioning System Module) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the GPSM (Global Positioning System Module) 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 GPSM (Global Positioning System Module). REFER to Global Positioning System Module (GPSM) . 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 any DTCs present.
