Pinpoint Test K: The Global Open Function is Inoperative/Does Not Operate Correctly - If Equipped
Refer to Wiring Diagram Set 100 (Fusion/Milan/MKZ, Fusion Hybrid, Milan Hybrid, MKZ Hybrid), Power Windows for schematic and connector information. Diagrams By Number
NOTE: The global open feature may be enabled/disabled via scan tool or in some cases modified by the customer following a procedure listed in the vehicle Owner's Literature. For a complete list of available programmable parameters, refer to the Module Configuration and Parameter Chart in Module Configuration [1][2]Initial Inspection and Diagnostic Overview.
Normal Operation
When the unlock button of the Remote Keyless Entry (RKE) transmitter is held for 2 seconds, the global open activates. The Smart Junction Box (SJB) sends a signal to the LH and RH front power window motors to activate the one-touch down operation of both front windows.
The global open feature does not operate if the accessory delay relay is active.
- DTC B2947 (Global Opening/Closing Circuit Open) - sets when the SJB detects the global open circuit is open or shorted to ground.
- DTC B2949 (Global Opening/Closing Circuit Short to Battery) - sets when the SJB detects the global open circuit is shorted to voltage.
This pinpoint test is intended to diagnose the following:
- RKE transmitters
- Wiring, terminals or connectors
- SJB
- Power window motors not initialized
PINPOINT TEST K: THE GLOBAL OPEN FUNCTION IS INOPERATIVE/DOES NOT OPERATE CORRECTLY - IF EQUIPPED
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: The global open feature must be enabled and one-touch up/down must be operational for the global open function to operate correctly. Make sure the global open feature is enabled and one-touch up/down is operational before proceeding with this diagnostic.

Yes
For B2949, GO to K2.
For B2947, GO to K5.
No
GO to K7.
-------------------------------------------------
K2 CHECK THE GLOBAL OPEN CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: SJB C2280C.
- Ignition ON.
- Measure the voltage between SJB C2280C-10, circuit CPW01 (BN/BU), harness side and ground.
- Is the voltage greater than 10 volts?
Yes
GO to K3.
No
GO to K9.
-------------------------------------------------
K3 CHECK THE GLOBAL OPEN CIRCUIT FOR A SHORT TO VOLTAGE

- Measure the voltage between SJB C2280C-10, circuit CPW01 (BN/BU), harness side and ground.
- Is the voltage greater than 10 volts?
Yes
GO to K4.
No
INSTALL a new LH front power window motor. REFER to Window Regulator and Motor - Front Door Window Regulator and Motor - Front Door. INITIALIZE the LH front power window motor. REFER to Window Motor Initialization Testing and Inspection. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
-------------------------------------------------
K4 CHECK THE GLOBAL OPEN CIRCUIT FOR A SHORT TO VOLTAGE
- Disconnect: RH Front Power Window Motor C623.
- Measure the voltage between SJB C2280C-10, circuit CPW01 (BN/BU), harness side and ground.
- Is the voltage greater than 10 volts?
Yes
REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH and RH front window motors. REFER to Window Motor Initialization Testing and Inspection. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
No
INSTALL a new RH front power window motor. REFER to Window Regulator and Motor - Front Door Window Regulator and Motor - Front Door. INITIALIZE the RH front power window motor. REFER to Window Motor Initialization Testing and Inspection. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
-------------------------------------------------
K5 CHECK THE GLOBAL OPEN CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: SJB C2280C.
- Disconnect: LH Front Power Window Motor C540.
- Disconnect: RH Front Power Window Motor C623.
- Measure the resistance between SJB C2280C-10, circuit CPW01 (BN/BU), harness side and LH front power window motor C540-2, circuit CPW01 (BN/BU), harness side; and between SJB C2280C-10, circuit CPW01 (BN/BU), harness side and RH front power window motor C623-2, circuit CPW01 (BN/BU), harness side.
- Are the resistances less than 5 ohms?
Yes
GO to K6.
No
REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH and RH front power window motors. REFER to Window Motor Initialization Testing and Inspection. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
-------------------------------------------------
K6 CHECK THE GLOBAL OPEN CIRCUIT FOR A SHORT TO GROUND
- Measure the resistance between SJB C2280C-10, circuit CPW01 (BN/BU), harness side and ground.
- Is the resistance greater than 10,000 ohms?
Yes
GO to K9.
No
REPAIR the circuit. DE-INITIALIZE then INITIALIZE the LH and RH front power window motors. REFER to Window Motor Initialization Testing and Inspection. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
-------------------------------------------------
K7 CHECK THE RKE TRANSMITTER OPERATION
- Operate the RKE lock/unlock function using all of the RKE transmitters.
- Does the RKE lock/unlock function operate correctly with at least one of the RKE transmitters?
