Pinpoint Test Ag : B272D

NOTE: When taking measurements at DCSM harness connectors, do not insert the electrical probes into the female connector pins. Inserting the probes into connector pins can cause intermittent or open electrical connections after reassembly resulting in DTCs and system failure. Touching the tip of these connector pins is recommended instead.

AG1 CHECK THE DCSM FOR DTCs

Using a diagnostic scan tool, perform DCSM self-test.

Was DTC B272A or B272B retrieved in the self-test?

Yes	For DTC B272A, GO to Pinpoint Test AD . For DTC B272B, GO to Pinpoint Test AE .
No	GO to AG2.

AG2 MONITOR THE DCSM TED TEMPERATURE PIDs

Using a diagnostic scan tool, view DCSM PIDs.
- Passenger cushion thermal electric device (TED) temperature (PCSHTMP)
- Passenger back TED temperature (PBKTMP)
- Seat cushion thermal electric device temperature (CSHTEMP)
- Seat back thermal electric device temperature (BK_TEMP)

NOTE: Make sure the temperature of the climate controlled seats has stabilized before monitoring the PIDs. Not allowing stabilization can cause incorrect readings and lead to incorrect identification of components that are not damaged.

Monitor the TED temperature PIDs with the climate controlled seats off. Compare the PIDs of the front passenger seat to those of the driver seat, this can help identify if there is a concern with the front passenger seat cushion or backrest PID readings.

Are both front passenger seat TED temperature PIDs within 10 °C (18 °F) of the ambient temperature?

Yes	GO to AG3.
No	If the front passenger seat cushion PID varies 10 °C (18 °F) or more from ambient temperature, GO to AG16. If the front passenger seat backrest PID varies 10 °C (18 °F) or more from ambient temperature, GO to AG31.

AG3 CONFIRM THE FAULT IS IN THE SEAT CUSHION OR THE BACKREST

Ignition OFF.

Start the engine.

NOTE: If the seat shuts down before a 15 minute heat cycle has timed out, carry out the DCSM self-test and go to the DCSM DTC Chart to continue diagnostics.

NOTE: A crushed seat cushion foam pad or climate controlled seat manifold may be the cause of the fault. It may be necessary to sit on the seat or place something of reasonable size and weight on the seat to recreate the fault.

Set the passenger seat to high heat. Allow the seat to heat for at least 15 minutes while monitoring the TED temperature PIDs of the passenger seat. If necessary, when the seat times out after 15 minutes, set the passenger seat to high heat once again.

Do the passenger seat cushion TED and backrest TED PIDs vary more than 60 ° C (108 ° F) from each other?

Yes	If the front passenger seat cushion PID is 60 °C (108 °F) hotter than the backrest PID, GO to AG5. If the front passenger seat backrest PID is 60 °C (108 °F) hotter than the cushion PID, GO to AG20.
No	GO to AG4.

AG4 CHECK THE TED COOLING PERFORMANCE

Check the TEDs cooling performance on the passenger seat. Refer to Seating .

Did the TEDs pass the component test?

Yes	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.
No	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 air flow restrictions (TED inlets and outlets, TED -to-manifold connections, filters and ducts) and REPAIR as needed. CHECK for an intermittent wiring fault. REPAIR as needed.
