Diagnostic Steps

1
Scan the vehicle’s onboard diagnostics (OBD-II) system using a compatible scanner to retrieve error codes.
2

3
Inspect the battery and alternator for proper voltage output and connections.

Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Address Check Engine Light

Use the OBD-II scanner to read the error codes and note them down.
Based on the error codes, research specific repairs needed (e.g., replace faulty sensors, fix exhaust leaks).
Clear the codes and recheck after performing repairs.

3. Fix ABS Warning Light

Inspect the ABS sensor wiring and connectors for any damage or corrosion.
If the sensor is faulty, replace it using the socket set to remove the old sensor and install a new one.
After replacement, clear the codes and test the ABS system.

4. Resolve Oil Pressure Warning Light

Check the oil level using the dipstick and top up if necessary with the recommended oil type.
If the oil pressure sender unit is faulty, replace it by locating the unit, disconnecting the wiring harness, and using a socket to remove it.
Install the new sender and reconnect the harness.

5. Address Battery Warning Light

Use a multimeter to test battery voltage; it should read around 12.6 volts when the engine is off and 13.7-14.7 volts when running.
If voltage is out of range, check the alternator belt for wear and tension. Replace if necessary.
Inspect battery terminals for corrosion and clean them if needed.

6. Resolve Airbag Warning Light

Inspect the airbag connectors under the seats and at the steering wheel for any loose connections.
If the airbag module is faulty, consult the manufacturer for replacement.
Reset the airbag system using the scanner after repairs.
