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 B2729 or B2730 retrieved in the self-test? 

    1. Yes: For DTC B2729, REFER to Diagnostic Routine AJ: B2729 .

      For DTC B2730, REFER to Diagnostic Routine AK: B2730 .

    2. No: GO to 2  .
  2. MONITOR THE DCSM TED TEMPERATURE PIDs 
    1. Using a scan tool, view DCSM PIDs  .
      • Passenger Cushion TED Temperature (PCSHTMP)
      • Passenger Back TED Temperature (PBKTMP)
      • Seat Cushion TED Temperature (CSHTEMP)
      • Seat Back TED 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 PID values of the driver seat to those of the front passenger seat. This can help identify if there is a concern with the driver seat cushion or backrest PID readings.

    Are both driver seat TED temperature PID values within 10 C (18 F) of the ambient temperature? 

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

      If the driver seat backrest PID value 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.

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

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

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

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

    2. No: GO to 4  .
  4. CHECK THE TEDs  COOLING PERFORMANCE
    1. Check the TED cooling performance on the driver 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: Driver Seat Side Air Bag C3051.
    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 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 CHS03 (GN/BN) and RHS03 (GY/OG). GO to  36.
    2. No: INSTALL a new 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-12, circuit CHS09 (GY), harness side and the negative lead to C3265C-15, circuit RHS03 (GY/OG), harness side when measuring.
