Automatic Transaxle External Controls -- Electric Ford Focus ST III

Overview

The transmission selector lever linkage consists of

1. a selector lever cable that connects the transmission manual control lever to the selector lever assembly.
2. a brake shift interlock actuator that is integral to the selector lever assembly.

The selector lever assembly

1. locks the transmission selector lever in the PARK position when the ignition switch is in the LOCK position.
2. requires the transmission selector lever to be in the PARK position to turn the ignition switch to the LOCK position.

Range Selection

This transmission has 5 range positions: P, R, N, D and L.

Park

In the PARK position

1. the parking pawl locks the output shaft to the case.
2. the ignition key can be removed.
3. the ignition switch can be cycled from OFF to START or RUN. The ready indicator light will illuminate on the IPC (instrument panel cluster) when the ignition switch is cycled to the START position.

Reverse

In the REVERSE position

1. the vehicle may be operated in a rearward direction.
2. the reverse lamps are illuminated.
3. the ready lamp light is not illuminated, it lights when the ignition switch is cycled to the START position, there is no reverse gear engagement.

Neutral

In the NEUTRAL position

1. no power flows through the transmission.
2. the output shaft is disengaged from the drive wheels.

Drive

The DRIVE position provides

1. low speed driving.
2. acceleration.
3. cruise conditions.
4. deceleration.
5. maximum fuel economy during normal operation.

If the ready indicator light is not illuminated, which lights when the ignition switch is cycled to the START position, there is no forward gear engagement.

Low

The LOW position provides

1. engine braking.
2. improved traction on slippery roads.

If the ready indicator light is not illuminated, which lights when the ignition switch is cycled to the START position, there is no forward gear engagement.

Brake Shift Interlock

The brake shift interlock system prevents a shift out of PARK unless the brake pedal is depressed. The brake shift interlock system has a brake shift interlock actuator mounted on the floor selector lever assembly. If the ignition switch is in the RUN position, the brake shift interlock actuator is continually on unless the brake pedal is depressed.

Brake Shift Interlock Actuator

The brake shift interlock system consists of

1. a brake shift interlock actuator that is integral to the selector lever assembly.
2. an ignition switch.
3. a BPP (brake pedal position) switch.
4. a BCM (body control module).

Selector Lever Cable

The selector lever cable consists of

1. a cable that connects the transmission manual control lever to the selector lever assembly.
2. a cable grommet that is fastened to the floor pan.
3. adjuster locking tab at the transmission manual control lever.

Selector Lever

The selector lever consists of

1. a selector lever knob.
2. a brake shift interlock actuator that is integral to the selector lever assembly.

Normal Operation and Fault Conditions

The Body Control Module (BCM) provides power to the Brake Shift Interlock Actuator (BSIA). When the Body Control Module (BCM) receives a brake pedal applied input, 12 volts are applied to the brake shift interlock solenoid. When the solenoid is energized, the plunger is pulled inward allowing the selector lever to moved from the PARK position.

Possible Sources

1. Connectors damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals
2. Brake Shift Interlock Actuator (BSIA)
3. Body Control Module (BCM)

DTC FAULT TRIGGER CONDITIONS

PINPOINT TEST A: BRAKE SHIFT INTERLOCK ACTUATOR

1. A1 READ AND RECORD ALL DTCS Read and record all DTCs . Is DTC B1319:11 and/or B1379:15 set? Yes : For DTC B1319:11 GO to A2 For DTC B1379:15 GO to A3 No : The issue may not be the Brake Shift Interlock Actuator (BSIA) electrical system, go to «SYMPTOM CHARTS»(/ford/focus-st/iii-2012-2015/remont/automatic-trans/#automatic-transaxle-external-controls-electric) .
2. A2 CHECK THE BRAKE SHIFT INTERLOCK ACTUATOR POWER CIRCUIT FOR A SHORT TO GROUND Disconnect Floor Shifter C3245 . Disconnect BCM C2280C . Measure the resistance between: Positive Lead Measurement/Action Negative Lead C3245-3 Ground Is the resistance greater than 10, 000 ohms? Yes : INSTALL a new selector lever assembly. REFER to: «SELECTOR LEVER ASSEMBLY»(/ford/focus-st/iii-2012-2015/remont/automatic-trans/#automatic-transaxle-external-controls-electric) . No : REPAIR the circuit. CLEAR the DTC.
3. A3 CHECK THE BRAKE SHIFT INTERLOCK ACTUATOR POWER CIRCUIT FOR AN OPEN Disconnect Floor Shifter C3245 . Disconnect BCM C2280C . Measure the resistance between: Positive Lead Measurement/Action Negative Lead C3245-3 C2280C-41 Is the resistance less than 5 ohms? Yes : GO to A4 No : REPAIR the circuit. CLEAR the DTC.
4. A4 CHECK THE BRAKE SHIFT INTERLOCK ACTUATOR GROUND CIRCUIT FOR AN OPEN Measure the resistance between: Positive Lead Measurement/Action Negative Lead C3245-4 Ground Is the resistance less than 5 ohms? Yes : GO to A5 No : REPAIR the circuit. CLEAR the DTC .
5. A5 CHECK BRAKE SHIFT INTERLOCK ACTUATOR POWER CIRCUIT FOR VOLTAGE Ignition ON. Measure for voltage between: Positive Lead Measurement/Action Negative Lead C3245-3 Ground Is any voltage present? Yes : REPAIR the circuit. CLEAR the DTC . No : INSTALL a new selector lever assembly. REFER to: «SELECTOR LEVER ASSEMBLY»(/ford/focus-st/iii-2012-2015/remont/automatic-trans/#automatic-transaxle-external-controls-electric) .

1. Rotate the manual control lever clockwise until it stops. Rotate the manual control lever counterclockwise one detent.
2. Set the selector lever to the (D) position.
3. Verify that the vehicle only starts in PARK and NEUTRAL and the reversal lamps illuminate in REVERSE.

1. NOTE: If it is necessary to use the override procedure to move the selector lever out of the PARK position, it is possible that an electrical failure has occurred. Using the scan tool check for Diagnostic Trouble Codes (DTCs). This vehicle is equipped with a brake shift interlock feature that prevents the selector lever from being moved out of PARK when the ignition is in the ON position until the brake pedal is applied. If the selector lever cannot be moved out of the PARK position when the ignition is in the ON position and the brake pedal is applied: Fully apply the parking brake lever. Set ignition switch to the 0 position (Ignition off).
2. NOTE: Move the brake shift interlock lever forward and hold the brake shift interlock lever while pulling the gearshift lever out of the PARK position and into the NEUTRAL position. Screwdriver.
3. Apply the brake pedal and start the vehicle.
4. Fully release the parking brake.
