Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box and find the specific cruise control fuse.
Use a fuse puller or pliers and check if the fuse is blown.
If blown, replace with a new fuse of the same amperage.

3. Test Brake Pedal Position Switch

Locate the brake pedal position switch under the dashboard.
Check for proper alignment and ensure it is functioning correctly.
If faulty, replace the brake pedal position switch:
1. Disconnect the wiring harness.
2. Remove the mounting screws and take out the switch.
3. Install the new switch and reconnect the wiring harness.

4. Inspect Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and use a multimeter to check the resistance:
1. Refer to the service manual for the correct resistance values.
2. If readings are out of specification, replace the TPS.
To replace, remove the mounting screws, take out the old sensor, and install the new one.

5. Check Cruise Control Module

Inspect the wiring harness connected to the cruise control module for any signs of damage or corrosion.
Ensure all connections are secure and free from moisture.
If the module is faulty, replace it by following these steps:
1. Disconnect the electrical connector.
2. Remove any mounting screws.
3. Install the new module and reconnect the wiring.
