Pinpoint Test D: DTC B11D6:11 Or DTC B11D6:15

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: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to BATTERY DISCONNECT .
  1. D1 CHECK THE DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND SOD-L AND SOD-R SELF-TESTS 
    • Check the SOD-L  and SOD-R  DTCs from the continuous and on-demand self-tests.
    • Are any SOD-L or SOD-R DTCs recorded? 
    • Yes:  For DTC B11D6:11, GO to  D2.

      For DTC B11D6:15, GO to  D4.

      For all other DTCs, REFER to DTC TABLES .

    • No:  For the LEDs constantly on with no DTCs, GO to  D4.

      Otherwise, Go To PINPOINT TEST I .

  2. D2 CHECK THE EXTERIOR MIRROR BLIS™/CTA LED SUPPLY CIRCUIT FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Disconnect: SOD-L  C4230 or SOD-R  C4229.
    • For the SOD-L  , measure the resistance between the SOD-L  C4230-6, circuit CRB04 (YE/GN), harness side and ground.
    • For the SOD-R  , measure the resistance between the SOD-R  C4229-6, circuit CRB02 (BU./BAN), harness side and ground.

    • Is the resistance greater than 10,000 ohms? 
    • Yes:  GO to  D3.
    • No:  REPAIR the circuit. CLEAR the DTCs. TEST the system for normal operation.
  3. D3 CHECK THE EXTERIOR MIRROR BLIS™/CTA LED SUPPLY CIRCUIT FOR A SHORT TO GROUND WITH THE LED DISCONNECTED 
    • Disconnect: Left Exterior Mirror BLIS™  /CTA  LED Connector Or Right Exterior Mirror BLIS™  /CTA  LED Connector.
    • For the SOD-L  , measure the resistance between the SOD-L  C4230-6, circuit CRB04 (YE/GN), harness side and ground.
    • For the SOD-R  , measure the resistance between the SOD-R  C4229-6, circuit CRB02 (BU./BAN), harness side and ground.
      • Fig 2: Measuring Resistance Between SOD-R C4229-6, Circuit CRB02 (BU./BAN), Harness Side & Ground

    • Is the resistance greater than 10,000 ohms? 
    • Yes:  INSTALL a new exterior mirror for the indicator in question. REFER to REMOVAL AND INSTALLATION .
    • No:  REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
  4. D4 CHECK THE EXTERIOR MIRROR BLIS™/CTA LED SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: SOD-L  C4230 or SOD-R  C4229.
    • Ignition ON.
    • For the SOD-L  , measure the voltage between the SOD-L  C4230-6, circuit CRB04 (YE/GN), harness side and ground.
    • For the SOD-R  , measure the voltage between the SOD-R  C4229-6, circuit CRB02 (BU./BAN), harness side and ground.
      • Fig 3: Measuring Voltage Between SOD-R C4229-6, Circuit CRB02 (BU./BAN), Harness Side & Ground

    • Is any voltage present? 
    • Yes:  REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
    • No:  GO to  D5.
  5. D5 CHECK THE EXTERIOR MIRROR BLIS™/CTA LED SUPPLY CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: Exterior Mirror Indicator Left Or Exterior Mirror Indicator Right.
    • For the SOD-L  , measure the resistance between the SOD-L  C4230-6, circuit CRB04 (YE/GN), harness side and the left exterior mirror BLIS™  /CTA  LED pin 1, harness side.
    • For the SOD-R  , measure the resistance between the SOD-R  C4229-6, circuit CRB02 (BU./BAN), harness side and the right exterior mirror BLIS™  /CTA  LED pin 1, harness side.
      • Fig 4: Checking Exterior Mirror BLIS™/CTA LED Supply Circuit For An Open

    • Is the resistance less than 5 ohms? 
    • Yes:  GO to  D6.
    • No:  REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.
  6. D6 CHECK THE EXTERIOR MIRROR BLIS™/CTA LED GROUND CIRCUIT FOR AN OPEN 
    • Disconnect: Negative Battery Cable.
    • For the SOD-L  , measure the resistance between the left exterior mirror BLIS™  /CTA  LED pin 2, harness side and ground.
    • For the SOD-R  , measure the resistance between the right exterior mirror BLIS™  /CTA  LED pin 2, harness side and ground.
      • Fig 5: Checking Exterior Mirror BLIS™/CTA LED Ground Circuit For An Open
      G06261026Courtesy of FORD MOTOR CO.
    • Is the resistance less than 5 ohms? 
    • Yes:  For the SOD-L  DTC B11D6:15, GO to  D7. For the SOD-R  DTC B11D6:15, GO to  D8.
    • No:  REPAIR the circuit in question. CLEAR the DTCs. TEST the system for normal operation.

    • Disconnect the SOD-L  connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the SOD-L  connector and make sure it seats correctly.
    • Operate the system and verify the concern is still present.
