Solution

1. Preparation

Gather required tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the 'ON' position (do not start the engine).
Retrieve and record any error codes. Clear the codes if applicable.

3. Inspect Ignition Switch

Remove the steering column cover using a socket set.
Check the ignition switch for proper operation; ensure it returns to the 'OFF' position without sticking.
If faulty, replace the ignition switch as per manufacturer specifications.

4. Check Accessory Settings

Start the vehicle and navigate to the settings menu on the dashboard display.
Look for any options related to interior lighting or accessory delay. Adjust settings if necessary.

5. Examine Fuses

Locate the fuse box (refer to the owner's manual for exact location).
Inspect fuses associated with the dashboard lights; replace any that are blown with fuses of the same amperage.

6. Test Battery and Alternator

Use a multimeter to check battery voltage (should be around 12.6 volts with the engine off).
Ensure tight connections on the battery terminals and alternator.
If voltage is low, consider replacing the battery or checking the alternator output.

7. Inspect Body Control Module (BCM)

If all previous steps are clear, inspect the BCM for any faults.
If necessary, consult a professional to run diagnostics on the BCM and perform software updates or replacements.
