Module Communications Network DTCS

COMMUNICATION NETWORK DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC	Description	Source	Perform Test
U0002	High Speed CAN Communication Bus Performance	Instrument cluster	The module could not communicate on the network at a point in time. The fault is currently not present. CLEAR the DTC. REPEAT the network test with the scan tool.
U0011	Medium Speed CAN Communication Bus Performance	Instrument cluster	The module could not communicate on the network at a point in time. The fault is currently not present. CLEAR the DTC. REPEAT the network test with the scan tool.
U0073	Control Module Communication Bus Off	Anti-lock brake system (ABS) module	The module could not communicate on the network at a point in time. The fault is currently not present. CLEAR the DTC. REPEAT the network test with the scan tool.
U0073	Control Module Communication Bus Off	Vehicle security module (VSM)	The module could not communicate on the network at a point in time. The fault is currently not present. CLEAR the DTC. REPEAT the network test with the scan tool.
U0155	Lost Communication With Instrument Panel Cluster (IC) Control Module	VSM	If the instrument cluster failed the network test, go to Pinpoint Test C . Otherwise, REFER to INSTRUMENT CLUSTER article.
U1900	CAN Communication Bus Fault-Receive Error	ABS module	Go to for module that failed network test.
U1900	CAN Communication Bus Fault-Receive Error	Instrument cluster	Go to for module that failed network test.
U1901	CAN Network #2 Communication Bus Fault - Receive Error	ABS module	REFER to VEHICLE DYNAMIC SYSTEMS article.
U2023	Fault Received From External Node	Instrument cluster	U2023 is set when a module receives invalid network data from another module with a faulted input. RETRIEVE and REPAIR all non-network DTCs in the other modules on the network. REFER to MULTIFUNCTION ELECTRONIC MODULES article for a list of all DTCs.
U2023	Fault Received From External Node	VSM	U2023 is set when a module receives invalid network data from another module with a faulted input. RETRIEVE and REPAIR all non-network DTCs in the other modules on the network. REFER to MULTIFUNCTION ELECTRONIC MODULES article for a list of all DTCs.
