N4 CHECK FOR CORRECT GPSM (GLOBAL POSITIONING SYSTEM MODULE) OPERATION
corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary
Reconnect the GPSM connector and related in-line connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.
Is the concern still present?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new GPSM. REFER to: Global Positioning System Module (GPSM) (415-00A Information and Entertainment System - General Information - Vehicles With: AM/FM/CD/SYNC, Removal and Installation). |
|---|---|
No | The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. |
The Accessory Protocol Interface Module (APIM) Does Not Respond To The Diagnostic Scan Tool
Refer to Wiring Diagrams Cell 14 for schematic and connector information.
Refer to Wiring Diagrams Cell 132 for schematic and connector information.
Refer to Wiring Diagrams Cell 133 for schematic and connector information.
Normal Operation and Fault Conditions
The APIM communicates with the diagnostic scan tool through the HS-CAN1 and communicates with other modules through the HS-CAN3 and the MS-CAN (touchscreen only). Diagnostic messages to modules on the HS-CAN3 and MS-CAN are sent/received between the DLC and the diagnostic scan tool through the HS-CAN2 circuits at the DLC, and translated through the GWM.
