Pinpoint Test S: DTC B111D

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. S1 CHECK THE TED BLOWER CIRCUIT FOR A SHORT TO GROUND 
    NOTE: If a seat equipped with a seat mounted side air bag is being serviced, the Supplemental Restraint System (SRS) must be depowered. Refer to SUPPLEMENTAL RESTRAINT SYSTEM .
    NOTE: The air bag warning lamp illuminates when the Restraints Control Module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate an SRS fault.
    NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
    • Ignition OFF.
      • WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any air bag module when the battery is connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.
    • For vehicles equipped with seat side air bags, carry out the following:
      • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM .
      • Disconnect the passenger seat side air bag module C339.
      • Connect the battery ground cable. Refer to BATTERY, MOUNTING AND CABLES .
    • Disconnect: DCSM C3265C.
    • Disconnect: Passenger Cushion TED C3040.
    • Disconnect: Passenger Backrest TED C3039.
    • Measure the resistance between DCSM C3265C-8, circuit CHS08 (BN/YE), harness side and ground.

    • Is the resistance greater than 10, 000 ohms? 
    • Yes  : GO to S2.
    • No  : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.

      For vehicles equipped with seat side air bags, DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C339. REPOWER the SRS. REFER to SUPPLEMENTAL RESTRAINT SYSTEM .

  2. S2 CHECK FOR A SHORT BETWEEN THE TED BLOWER CIRCUITS 
    • Measure the resistance between DCSM C3265C-7, circuit RHS08 (VT/WH), harness side and C3265C-8, circuit CHS08 (BN/YE), harness side.

    • Is the resistance greater than 10, 000 ohms? 
    • Yes  : GO to S3.
    • No  : REPAIR the circuits. CLEAR the DTCs. REPEAT the self-test.

      For vehicles equipped with seat side air bags, DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C339. REPOWER the SRS. REFER to SUPPLEMENTAL RESTRAINT SYSTEM .

  3. S3 CHECK THE BACKREST BLOWER AND CUSHION BLOWER RESISTANCES 
      NOTE: The ohmmeter must be connected with the positive lead to pin 2 and the negative lead to pin 4 when measuring. Ohmmeter leads incorrectly connected can result in false readings and lead to incorrect identification of components that are not faulty.
    • Measure the resistance between:
      • passenger cushion TED C3040 pins 2 and 4, component side.
      • passenger backrest TED C3039 pins 2 and 4, component side.

    • Are the resistances between 4, 000 and 10, 000 ohms? 
    • Yes  : GO to S4.
    • No  : If the passenger cushion TED resistance is not  between 4, 000 and 10, 000 ohms, INSTALL a new passenger cushion TED. REFER to SEAT CUSHION - FRONT, BUCKET SEAT . CLEAR the DTCs. REPEAT the self-test.

      For vehicles equipped with seat side air bags, DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C339. REPOWER the SRS. REFER to SUPPLEMENTAL RESTRAINT SYSTEM .

      If the passenger backrest TED resistance is not  between 4, 000 and 10, 000 ohms, INSTALL a new passenger backrest TED. REFER to SEAT BACKREST - FRONT, BUCKET SEAT . CLEAR the DTCs. REPEAT the self-test.

      DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C339. REPOWER the SRS. REFER to SUPPLEMENTAL RESTRAINT SYSTEM .

  4. S4 CHECK FOR CORRECT DCSM OPERATION 
    • Disconnect all the DCSM electrical connectors.
    • Check the harness and component side connectors for the following:
      • corrosion.
      • damaged pins.
      • pushed-out pins.
    • Connect all the DCSM electrical connectors and make sure they seat correctly.
    • Start the engine.
    • Operate the climate controlled seats and verify system operation.
    • CLEAR all CMDTCs.
    • Enter the following diagnostic mode on the scan tool: Self Test - DCSM.
    • Is DTC B111D still present? 
    • Yes  : INSTALL a new DCSM. REFER to DUAL CLIMATE CONTROLLED SEAT MODULE (DCSM) . CLEAR all CMDTCs. REPEAT the self-test.

      For vehicles equipped with seat side air bags, DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C339. REPOWER the SRS. REFER to SUPPLEMENTAL RESTRAINT SYSTEM .

    • No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR all CMDTCs. REPEAT the self-test.

      For vehicles equipped with seat side air bags, DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C339. REPOWER the SRS. REFER to SUPPLEMENTAL RESTRAINT SYSTEM .
