Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Address Fault Codes

Sub-step 1: Clear any fault codes using the OBD-II scanner.
Sub-step 2: If the warning light persists after clearing, note the specific error codes for further investigation.
Tools Required: OBD-II scanner

3. Fluid Check and Replacement

Sub-step 1: Check engine oil level using the dipstick; replace oil if low or dirty.
Sub-step 2: Inspect and top off coolant to the proper level.
Sub-step 3: Check transmission fluid and replace if necessary.
Tools Required: Oil filter wrench, socket set, funnel

4. Electrical Inspection

Sub-step 1: Inspect battery connections for corrosion and clean as necessary.
Sub-step 2: Test the battery voltage; replace if below 12.4 volts.
Sub-step 3: Check the alternator output while the engine is running; it should read between 13.5 and 14.5 volts.
Tools Required: Multimeter

5. Visual and Functional Inspection

Sub-step 1: Examine wiring harnesses for wear or damage; repair or replace as needed.
Sub-step 2: Ensure all fuses related to the dashboard and engine management are intact and functioning.
