Pinpoint Test C: Select Shift Does Not Operate/O/D Does Not Cancel (Vehicles Equipped With A 3.0L Engine)

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.

C1 TEST BJB FUSE 47 (10A)
- Check fuse: Battery Junction Box (BJB) 47 (10A).
- Is the resistance less than 5 ohms?
- Yes: GO to C2.
- No: REPAIR circuit CBK03 (GY) for a short to ground. INSTALL a new fuse. TEST the system for normal operation.
C2 CHECK FOR VOLTAGE AT THE SELECTOR LEVER CONNECTOR
- Disconnect: Selector Lever Electrical 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 C4.
- No: GO to C3.
C3 TEST THE SELECT SHIFT POWER SUPPLY CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: BJB Fuse 47 (10A).
- Measure the resistance between the output side of BJB fuse 47 (10A) and selector lever harness C3233-8 circuit CBK03 (GY), vehicle harness side.
