PINPOINT TEST Z: DTCs B1113 AND B111B

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: When taking measurements at Dual Climate Controlled Seat Module (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 Diagnostic Trouble Codes (DTCs) and system failure. Touching the tip of these connector pins is recommended instead.
NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition switch is ON.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
  1. Z1 CHECK THE TED CIRCUITS FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Depower the SRS  . Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
    • Disconnect: Passenger Seat Side Air Bag Module C313.
    • Disconnect: DCSM  C3305a.
    • Measure the resistance between DCSM  C3305a, harness side and ground using the following table below:

    • Are the resistances greater than 10,000 ohms? 
  1. Z2 CHECK THE TED CIRCUITS FOR A SHORT TO VOLTAGE 
    • Connect the battery ground cable. Refer to BATTERY, MOUNTING AND CABLES .
      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.
    • Ignition ON.
    • Measure the voltage between DCSM  C3305a, harness side and ground using the following table below:
