Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on the electrical system.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.

2. Inspect and Replace Fuses

Locate the fuse box in your Honda CR-V (usually under the dashboard or in the engine compartment).
Identify the fuse related to the cruise control.
Remove the fuse using a fuse puller or pliers and inspect it.
- If the fuse is blown, replace it with a new fuse of the same amperage.

3. Brake Switch Inspection

Locate the brake switch, usually mounted above the brake pedal.
Using a multimeter, check for continuity in the switch when the brake pedal is pressed.
- If the switch is faulty, remove the old switch and install a new one.
Ensure that the switch is properly adjusted to activate when the brake pedal is pressed.

4. Cruise Control Switch Check

Remove the steering wheel cover to access the cruise control switch.
Inspect the wiring and connectors for signs of damage or corrosion.
Use a multimeter to test the switch for proper functionality.
- If defective, replace with a new cruise control switch.

5. Throttle Position Sensor Inspection

Locate the throttle position sensor on the throttle body.
Use a multimeter to check the voltage output from the sensor while manually moving the throttle.
- If the readings are out of specifications, replace the throttle position sensor.

6. Reassembly and Reconnect Battery

Ensure all components are securely reinstalled and reconnected.
Reconnect the vehicle's battery and clear any diagnostic trouble codes using the OBD-II scanner.
