Yes
INSTALL a new APIM. REFER to Accessories and Optional Equipment. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Pinpoint Test R: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, One Or More Modules Are Not
Responding During Network Test
Refer to Wiring Diagram Set 14, Module Communications Network for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Normal Operation
An open circuit (MS-CAN + or MS-CAN -) may cause intermittent or unreliable communication to all modules on the Medium Speed Controller Area
Network (MS-CAN). The MS-CAN is used for communication between the following modules:
-
Accessory Protocol Interface Module (APIM)
-
Audio Control Module (ACM)
-
Driver Seat Module (DSM)
-
Global Positioning System Module (GPSM)
-
HVAC module
-
Instrument Cluster (IC)
-
Parking Aid Module (PAM)
-
Power Running Board (PRB) module
-
Rear Entertainment Module (RETM)
-
Satellite Digital Audio Receiver System (SDARS) module
-
Smart Junction Box (SJB)
In the event that 1 of the 2 network circuits (MS-CAN + or MS-CAN -) becomes open to a module on the network, unreliable network communication to
all modules on the network may result.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
PINPOINT TEST R: INTERMITTENT NO MS-CAN COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING
DURING NETWORK TEST
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint
test. See: Initial Inspection and Diagnostic Overview/Module Communications Network/Inspection and Verification
NOTE: Various network DTCs will set while disabling modules in this test procedure which will need to be cleared after the diagnostic procedure is
completed.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
