PINPOINT TEST D : SELECTSHIFT(TM) DOES NOT OPERATE CORRECTLY

D1 CHECK FUSE 47 (10A)

- Check fuse: Battery Junction Box (BJB) 47 (10A).

Is the resistance less than 5 ohms?

Yes
GO to D2.

No
REPAIR circuit CBK03 (GY) for a short to ground. INSTALL a new fuse. CLEAR the DTCs. TEST the system for normal operation.

D2 CHECK THE POWER CIRCUIT FOR VOLTAGE

- Disconnect: Selector Lever C3233.

- Ignition ON.

- Measure the voltage between selector lever harness C3233-8, circuit CBK03 (GY), vehicle harness side and ground.





Is the voltage greater than 10 volts?

Yes
GO to D4.

No
GO to D3.

D3 CHECK THE POWER CIRCUIT FOR AN OPEN

- Ignition OFF.

- Disconnect: BJB (Battery Junction Box) Fuse 47 (10A).

- Measure the resistance between the output side of BJB (Battery Junction Box) fuse 47 (10A) and selector lever harness C3233-8 circuit CBK03 (GY), vehicle harness side.





Is the resistance less than 5 ohms?

Yes
INSTALL a new BJB (Battery Junction Box).

No
REPAIR circuit CBK03 (GY) for an open. CLEAR the DTCs. TEST the system for normal operation.

D4 CHECK THE GROUND CIRCUIT

- Measure the resistance between selector lever C3233-11, circuit RE407 (YE/VT) (Fusion) or circuit GD116 (BK/VT) (MKZ) and ground.





Is the resistance less than 5 ohms?

Yes
GO to D5.

No
REPAIR circuit RE407 (YE/VT) (Fusion) or circuit GD116 (BK/VT) (MKZ) for an open. CLEAR the DTCs. TEST system for normal operation.

D5 CHECK CIRCUITS FOR A SHORT TO GROUND

- Disconnect: Transmission Control Module (TCM) C1533.

- Measure the resistance between TCM (Transmission Control Module) C1533-3, circuit CET43 (GY) and ground.





- Measure the resistance between TCM (Transmission Control Module) C1533-4, circuit CET42 (GN/VT) and ground.





Is the resistance greater than 10,000 ohms?

Yes
GO to D6.

No
REPAIR circuit CET43 (GY) or circuit CET42 (GN/VT) for a short to ground. CLEAR the DTCs. TEST system for normal operation.

D6 CHECK CIRCUITS FOR AN OPEN

- Measure the resistance between TCM (Transmission Control Module) C1533-3, circuit CET43 (GY) and selector lever C3233-9.





- Measure the resistance between TCM (Transmission Control Module) C1533-4, circuit CET43 (GY) and selector lever C3233-10.





Is the resistance less than 5 ohms?

Yes
INSTALL a new selector lever. REFER to Selector Lever - Fusion or Selector Lever - MKZ . CLEAR the DTCs. TEST the system for normal operation. If the condition still exists, INSTALL a new TCM.

No
REPAIR circuit CET43 (GY) or circuit CET42 (GN/VT) for an open. CLEAR the DTCs. TEST system for normal operation.
