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

Visual Inspection and Diagnostic Pre-checks

- Inspect to make sure that the navigation SD (Secure Digital) card is present in the SD (Secure Digital) card slot.

Pinpoint Test

1. CHECK THE NAVIGATION SYSTEM OPERATION

1. Verify the navigation system operation.

Does the audio system display " SD (Secure Digital) CARD FAULT"?






2. VERIFY THE SD (Secure Digital) CARD WITH NAVIGATION MAP IS PRESENT

1. Check for the presence of an SD (Secure Digital) card with map data in the SD (Secure Digital) slot of the media hub.

Is the navigation map SD (Secure Digital) card present?






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

1. Using a scan tool, preform the APIM (Accessory Protocol Interface Module) and GPSM (Global Positioning System Module) self-tests.

Are any DTCs (Diagnostic Trouble Codes) present?






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

1. Ignition ON.

2. Using a scan tool, perform the network test.

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






5. CHECK FOR CORRECT GPSM (Global Positioning System Module) OPERATION

1. Ignition OFF.

2. Disconnect and inspect the GPSM (Global Positioning System Module) connector.

3. Repair:

- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals pins
- pushed-out pins - install new pins as necessary

4. Reconnect the GPSM (Global Positioning System Module) connector. Make sure it seats and latches correctly.

5. Operate the system and determine if the concern is still present.

Is the concern still present?
