Diagnostic Steps:

Use an OBD-II scanner to retrieve trouble codes from the vehicle's ECU.
Check for any recent modifications or changes in driving conditions.

Tools Required:

OBD-II scanner
Vehicle repair manual (for code interpretation)

Repair Instructions:

Based on the trouble code, inspect the relevant systems (e.g., ignition, fuel, exhaust).
Address the issue indicated by the code, such as replacing faulty sensors, fixing leaks, or servicing the ignition system.

2. Oil Pressure Warning Light

Symptoms:

Oil pressure warning light illuminated.
Potential engine noise or knocking sounds.

Diagnostic Steps:

Check the oil level using the dipstick.
Inspect for oil leaks around the engine and oil filter.

Tools Required:

Oil dipstick
Oil pressure gauge (for further testing)
Wrench set (for any repair)

Repair Instructions:

If oil level is low, add the appropriate oil type.
If oil pressure is low after checking with a gauge, inspect and replace the oil pump if necessary.
Replace any faulty oil pressure sensors.

3. Battery/Charging System Warning Light

Symptoms:

Battery warning light illuminated.
Electrical components (e.g., lights, radio) may flicker.

Diagnostic Steps:

Check battery terminals for corrosion and ensure they are tight.
Measure the voltage at the battery with a multimeter.

Tools Required:

Multimeter
Wrench set
Battery terminal cleaner

Repair Instructions:

Clean battery terminals and ensure connections are tight.
If voltage is below 12.6 volts with the engine off, or below 13.7 volts with the engine running, consider replacing the battery or the alternator.
Test the alternator output and replace if necessary.

4. Brake Warning Light

Symptoms:

Brake warning light illuminated.
Possible loss of brake performance.

Diagnostic Steps:

Check the brake fluid level in the reservoir.

Symptoms:

TPMS warning light illuminated.
Possible change in vehicle handling.

Diagnostic Steps:

Check tire pressures using a tire pressure gauge.
Inspect tires for visible damage or leaks.

Tools Required:

Tire pressure gauge
Air compressor (if tires need inflation)
Tire repair kit (if there are punctures)

Repair Instructions:

Inflate tires to the recommended pressure listed on the driver’s door jamb.
If the TPMS light remains on after correcting tire pressures, reset the TPMS using the vehicle’s onboard reset procedure.
Inspect TPMS sensors if issues persist.

6. ABS (Anti-lock Braking System) Warning Light
