U0140:00	Lost Communication With Body Control Module: No Sub Type Information	GO to PINPOINT TEST P: U0140:00
U0155:00	Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information	GO to PINPOINT TEST Q: U0155:00
U2100:00	Initial Configuration Not Complete: No Sub Type Information	CHECK the service history for recent service actions related to the HVAC control module. This DTC sets due to incomplete or improper PMI procedures. If there have been recent service actions with this module, REPEAT the PMI procedure using as-built data. FOLLOW the diagnostic scan tool instructions. If there have been no recent service actions, INSTALL a new HVAC control module to correct the failure to retain configuration data. Refer to: HEATING, VENTILATION AND AIR CONDITIONING (HVAC) CONTROL MODULE .
U2101:00	Control Module Configuration Incompatible	CHECK the service history for recent service actions related to the HVAC control module and BCM . This DTC sets due to incomplete or improper PMI procedures. If there have been recent service actions with this module, REPEAT the PMI procedure using as-built data. FOLLOW the diagnostic scan tool instructions. If there have been no recent service actions, INSTALL a new HVAC control module to correct the failure to retain configuration data. Refer to: HEATING, VENTILATION AND AIR CONDITIONING (HVAC) CONTROL MODULE .
U3000:00	Control Module: No Sub Type Information	INSTALL a new HVAC control module. Refer to: HEATING, VENTILATION AND AIR CONDITIONING (HVAC) CONTROL MODULE .
