Diagnostic Overview

Navigation Is Inoperative

Refer to Wiring Diagram Set 130 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

REFER to Navigation System .

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

DTC (Diagnostic Trouble Code) Fault Trigger Conditions






Visual Inspection and Diagnostic Pre-checks

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

Pinpoint Test

1. CHECK THE FDIM (Front Display Interface Module) TOUCHSCREEN RH (Right Hand) UPPER TAB

1. Check the navigation status of the FDIM (Front Display Interface Module) touchscreen RH (Right Hand) upper tab.

Does the FDIM (Front Display Interface Module) touchscreen RH (Right Hand) upper tab read Navigation?








2. CHECK FOR SCAN TOOL COMMUNICATION WITH THE GPSM (Global Positioning System Module) AND APIM (Accessory Protocol Interface 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) and APIM (Accessory Protocol Interface Module)?








3. RETRIEVE THE DTCs (Diagnostic Trouble Codes) FROM THE APIM (Accessory Protocol Interface Module)

1. NOTE: If DTC (Diagnostic Trouble Code) B1215:00 is set in the APIM (Accessory Protocol Interface Module) and the RH (Right Hand) upper tab of the FDIM (Front Display Interface Module) touchscreen displays" SD (Secure Digital) CARD FAULT".

NOTE: If DTC (Diagnostic Trouble Code) U016A:00 is set in the APIM (Accessory Protocol Interface Module) and the RH (Right Hand) upper tab of the FDIM (Front Display Interface Module) touchscreen displays" NAVIGATION FAULT".

Using a scan tool, preform the APIM (Accessory Protocol Interface Module) self-test.

Are any DTCs (Diagnostic Trouble Codes) present?








4. VERIFY THE SD (Secure Digital) CARD WITH NAVIGATION MAP IS PRESENT AND FULLY SEATED

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 and fully seated?








5. VERIFY WITH A KNOWN GOOD SD (Secure Digital) CARD WITH NAVIGATION MAP

1. Using a known good SD (Secure Digital) card with map navigation, attempt to use the navigation system.

Does the navigation map operate correctly and is the SD (Secure Digital) fault not present?








6. RECHECK THE ORIGINAL SD (Secure Digital) CARD WITH NAVIGATION MAP

1. REINSTALL the original SD (Secure Digital) card with map data into the SD (Secure Digital) slot of the media hub and attempt to use the navigation system.

Does the navigation map operate correctly and is the SD (Secure Digital) fault not present?








7. RESET THE AUDIO SYSTEM MODULES AND RECHECK THE NAVIGATION SYSTEM OPERATION

1. Disconnect the battery for 5 minutes, then reconnect it.

2. Turn the infotainment system on and wait for the system to re-initialize.

3. Operate the navigation system.

Does the navigation system operate correctly?








8. REPROGRAM THE APIM (Accessory Protocol Interface Module)

1. Perform the APIM (Accessory Protocol Interface Module) Standard Programming and force a CIP (Consumer Interface Processor) reflash. REFER to Accessory Protocol Interface Module (APIM) Standard Programming Accessory Protocol Interface Module (APIM) Standard Programming.

2. Once the APIM (Accessory Protocol Interface Module) programming is complete and the system has re-initialized, confirm that the RH (Right Hand) upper tab of the FDIM (Front Display Interface Module) touchscreen displays" NAVIGATION" and the navigation system operates correctly.

Does the RH (Right Hand) upper tab of the FDIM (Front Display Interface Module) touchscreen displays" NAVIGATION" and the navigation system operate correctly?








9. CHECK FOR CORRECT APIM (Accessory Protocol Interface Module) OPERATION

1. Disconnect and inspect the APIM (Accessory Protocol Interface Module) connector.

2. Repair:

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

3. Reconnect the APIM (Accessory Protocol Interface Module) connector. Make sure it seats and latches correctly.

4. Wait 2 minutes for the APIM (Accessory Protocol Interface Module) to re-initialize.

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

Is the concern still present?
