B272C	Driver Differential Temperature Fault	On-Demand and Continuous	If on-demand, go to Pinpoint Test AP . If continuous only, and the system is operating, CHECK the TED cooling performance on the affected seat and VERIFY the system is operating correctly. REFER to Component Testing - Thermo-Electric Device (TED) Cooling Performance . If a concern is found, CHECK the affected seat cushion or backrest for correct installation of the climate controlled seat components (TED, manifold, air ducts and foam pad). CHECK for airflow restrictions (TED inlets and outlets, TED-to-manifold connections, filters and ducts) and REPAIR as needed. If OK, CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation. The DTC may have been set by extreme cabin temperatures or excessive sun-load on the seat causing the system to enter recovery mode. Occupant size and weight characteristics can also be a factor. If a concern cannot be found or duplicated, RETURN the vehicle to the customer.
B272D	Passenger Differential Temperature Fault	On-Demand and Continuous	If on-demand, go to Pinpoint Test AQ . If continuous only, and the system is operating, CHECK the TED cooling performance on the affected seat and VERIFY the system is operating correctly. REFER to Component Testing - Thermo-Electric Device (TED) Cooling Performance . If a concern is found, CHECK the affected seat cushion or backrest for correct installation of the climate controlled seat components (TED, manifold, air ducts and foam pad). CHECK for airflow restrictions (TED inlets and outlets, TED-to-manifold connections, filters and ducts) and REPAIR as needed. If OK, CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation. The DTC may have been set by extreme cabin temperatures or excessive sun-load on the seat causing the system to enter recovery mode. Occupant size and weight characteristics can also be a factor. If a concern cannot be found or duplicated, RETURN the vehicle to the customer.
B2730	Back Over-Temp Detected (Driver)	On-Demand and Continuous	Go to Pinpoint Test AR .
B6050	No Application Present	-	REFLASH with the latest operational software. REFER to MODULE CONFIGURATION . CLEAR the DTC. CARRY OUT the CCSM self-test.
