Test N: The Satellite Radio Receiver Does Not Respond To The Diagnostic Tool

PINPOINT TEST N: THE SATELLITE RADIO RECEIVER DOES NOT RESPOND TO THE DIAGNOSTIC TOOL


N1-N2:






N2-N3:






Normal Operation
The satellite radio receiver communicates with the diagnostic tool through the medium speed controller area network (CAN), circuits VDB06 (GY/OG) and VDB07 (VT/OG). Check the medium speed CAN circuits between the satellite radio receiver C3290 and the data link connector (DLC) C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the high speed CAN circuits, damage to the DLC C251, damage to the satellite radio receiver C3290, or a problem in an in-line connector.

Possible Causes
- medium speed CAN data plus circuit VDB06 (GY/OG) open
- medium speed CAN data minus circuit VDB07 (VT/OG) open
- satellite radio receiver C3290
- satellite radio receiver
