Pinpoint Test

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.
  1. CHECK THE DCSM FOR DTCs 
    1. Using a scan tool, perform DCSM self-test.

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

    1. Yes: For DTC B272A, REFER to Diagnostic Routine AD: B272A .

      For DTC B272B, REFER to Diagnostic Routine AE: B272B .

    2. No: GO to 2  .
  2. MONITOR THE DCSM TED TEMPERATURE PIDs 
    1. Using a 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)
    2. 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? 

    1. Yes: GO to 3  .
    2. No: If the front passenger seat cushion PID varies 10 C (18 F) or more from ambient temperature, GO to  16  .

      If the front passenger seat backrest PID varies 10 C (18 F) or more from ambient temperature, GO to  31  .

  3. CONFIRM THE FAULT IS IN THE SEAT CUSHION OR THE BACKREST
    1. Ignition OFF.
    2. Start the engine.
    3. 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.
      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.

      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? 

    1. Yes: If the front passenger seat cushion PID is 60 C (108 F) hotter than the backrest PID, GO to  5  .

      If the front passenger seat backrest PID is 60 C (108 F) hotter than the cushion PID, GO to  20  .

    2. No: GO to 4  .
  4. CHECK THE TED COOLING PERFORMANCE
    1. Check the TEDs  cooling performance on the passenger seat. REFER to Thermo-Electric Device (TED) Cooling Performance .

    Did the TEDs pass the component test? 

    1. 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.
    2. 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.
  5. CHECK THE TED INSTALLATION AND FOR A CRUSHED SEAT CUSHION
    1. WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

      Ignition OFF.

    2. Disconnect: Passenger Seat Side Air Bag C339.
    3. Remove the seat. REFER to Seat .
    4. Remove the seat cushion cover. REFER to Seat Cushion Cover .
    5. Inspect the seat cushion:
      • Is the cushion blower obstructed?
      • Is the blower filter restricted or plugged?
      • Is the TED correctly installed?
      • Is the seat cushion foam pad crushed or restricted?
      • Is the climate controlled seat manifold crushed or restricted?

    Is the TED correctly installed and are the foam pad and manifold free of any damage? 

    1. Yes: GO to 6  .
    2. No: Correctly INSTALL the cushion TED or INSTALL a new seat cushion foam pad and/or climate controlled seat manifold. GO to  36  .

    Is the resistance between 4, 000 ohms and 10, 000 ohms? 

    1. Yes: REPAIR circuits CHS08 (BN/YE) and RHS08 (VT/WH). GO to  36.
    2. No: INSTALL a new seat backrest TED. REFER to Seat Backrest Thermo-Electric Device (TED) . GO to  36.
  29. CHECK THE BLOWER SPEED CONTROL AND CIRCUIT RESISTANCE
    1. NOTE: Connect the ohmmeter with the positive lead to C3265C-4, circuit VHS21 (BU/WH), harness side and the negative lead to C3265C-7, circuit RHS08 (VT/WH), harness side when measuring. Ohmmeter leads incorrectly connected can result in false readings and lead to incorrect identification of components that are not damaged.

      Measure the resistance between DCSM C3265C-4, circuit VHS21 (BU/WH), harness side and DCSM C3265C-7, circuit RHS08 (VT/WH), harness side.
