Are the resistances less than 3 ohms?
Yes | GO to P4 |
|---|---|
No | REPAIR the circuit in question. |
P4 CHECK FOR CORRECT DSP (AUDIO DIGITAL SIGNAL PROCESSING MODULE) OPERATION
Ignition OFF. Disconnect and inspect the DSP connector and related in-line connectors. Repair:
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 DSP connector and related in-line connectors. Make sure it seats and latches 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 DSP. REFER to: Audio Digital Signal Processing (DSP) Module (415-00B Information and Entertainment System - General Information - Vehicles With: Touchscreen Display, 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 Radio Transceiver Module (RTM) Does Not Respond To The Diagnostic Scan Tool
Refer to Wiring Diagrams Cell 14 for schematic and connector information.
Refer to Wiring Diagrams Cell 117 for schematic and connector information.
Normal Operation and Fault Conditions
The RTM communicates on the MS-CAN and communicates with the diagnostic scan tool through the HS-CAN2. Diagnostic messages are sent/received through the HS-CAN2 circuits at the DLC, and are translated through the GWM to the MS-CAN.
