If your 2020 Ford Explorer's cruise control is not working, follow these detailed diagnostic and repair steps to identify and potentially fix the issue.

Step 1: Preliminary Checks

  • Check for Warning Lights: Inspect the dashboard for any warning lights that may indicate a related issue (e.g., ABS, engine, or traction control lights).
  • Inspect the Brake Pedal: Ensure that the brake pedal is not sticking or depressed when cruise control is activated.

Step 2: Use an OBD-II Scanner

  • Gather Tools: OBD-II scanner, vehicle owner's manual.
  • Connect the Scanner: Plug the OBD-II scanner into the vehicle's diagnostic port, usually located under the dashboard near the driver's seat.
  • Read Codes: Scan for any diagnostic trouble codes (DTCs) that may relate to the cruise control system. Common codes include P0571 (Cruise Control/Brake Switch A Circuit Range/Performance Problem).
Tools Required
  • OBD-II scanner
  • Multimeter
  • Screwdrivers (Phillips and flathead)
  • Torque wrench
  • Basic hand tools (wrenches, sockets)
  • Vehicle service manual (for specific torque specs and procedures)
Repair Instructions

Step 3: Inspect the Cruise Control Switch

  1. Remove the Steering Wheel Cover:
    • Use a screwdriver to remove screws securing the airbag module.
    • Disconnect the battery before working on the airbag system to prevent accidental deployment.
  2. Access the Cruise Control Switch:
    • Unscrew and detach the switch from the steering column.
  3. Test the Switch:
    • Use a multimeter to measure continuity across the cruise control switch terminals when activated.
    • If there is no continuity, the switch is faulty and needs replacement.

Step 4: Check Brake Light Switch

  1. Locate the Brake Light Switch:
    • It is typically located above the brake pedal.
  2. Test the Brake Light Switch:
    • Using a multimeter, check for continuity when the brake pedal is not pressed.
    • If the switch is open when the pedal is released, it may need adjustment or replacement.

Step 5: Inspect Wiring and Connectors

  1. Visual Inspection:
    • Check for any damaged or frayed wiring in the cruise control circuit, including connectors at the switch, brake pedal, and any related modules.
  2. Repair or Replace Damaged Wiring:
    • Use electrical tape or solder connections as needed to repair damaged wires.

Step 6: Check the Vehicle Speed Sensor (VSS)

  1. Locate the VSS:
    • Refer to the service manual for the exact location.
  2. Test the VSS:
    • Use a multimeter to check the output signal from the VSS while the vehicle is moving.
    • If the signal is weak or nonexistent, replace the VSS.

Step 7: Inspect the Fuses

  1. Locate the Fuse Box:
    • Find the fuse box under the dashboard or in the engine compartment.
  2. Check Fuses Related to Cruise Control:
    • Identify the fuse for cruise control (refer to the owner's manual).
    • If the fuse is blown, replace it with the same amperage.

Step 8: Reassemble and Test

  1. Reassemble Components:
    • Reattach any panels or covers that were removed during diagnosis.
  2. Reconnect the Battery:
    • Reconnect the negative battery terminal.
  3. Test the Cruise Control System:
    • Take the vehicle for a test drive to ensure cruise control engages and operates correctly.
Conclusion

If after following all these steps the cruise control still does not work, it may be necessary to consult a professional technician or visit a Ford dealership for further diagnostics. They have specialized equipment and software that can diagnose more complex electronic issues.
