Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts during repairs.

Tools Required:

OBD-II scanner
Tire pressure gauge
Wrench set
Multimeter

2. Addressing the Check Engine Light

Connect OBD-II Scanner
- Plug the scanner into the diagnostic port.
- Turn on the ignition without starting the engine.
- Read and note the error codes displayed.
Resolve Identified Issues
- Research error codes and rectify the underlying problems (e.g., replace faulty sensors, fix exhaust leaks).
- Clear the error codes using the OBD-II scanner after repairs.

3. Tire Pressure Monitoring System (TPMS) Reset

Check Tire Pressures
- Use the tire pressure gauge to ensure all tires are inflated to manufacturer specifications.
Reset TPMS
- Locate the TPMS reset button (if equipped) or follow vehicle-specific procedures using the dashboard settings to reset the system.

4. Battery and Electrical System Inspection

Inspect Battery Connections
- Check for corrosion on battery terminals and clean if necessary.
- Ensure battery connections are tight.
Test Battery Voltage
- Use a multimeter to check the battery voltage; it should read around 12.6 volts when the vehicle is off.
- If voltage is low, consider replacing the battery.
