Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
  • Safety Warnings: Ensure the vehicle is in park and the parking brake is engaged. Disconnect the battery before working on electrical components.
2. Scan and Clear Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Retrieve and document any error codes.
  • Clear the codes and observe if the dashboard light remains on after restarting the vehicle.
3. Battery and Connections
  • Inspect the battery terminals for corrosion and ensure they are tight.
  • Measure the battery voltage with a multimeter; if low, recharge or replace the battery.
  • Reconnect the battery terminals securely.
4. Check for Parasitic Draw
  • With the multimeter set to measure current, connect it in series with the negative battery terminal.
  • Note the current draw; if it exceeds 50mA, begin pulling fuses one by one to identify the circuit causing the drain.
5. Inspect Fuses and Relays
  • Identify the relevant fuses and relays associated with the dashboard light and electrical systems.
  • Replace any blown fuses and ensure relays are functioning correctly.
  • Reassemble any panels or covers removed during inspection.
6. Ignition Switch Replacement (if necessary)
  • If the ignition switch is determined faulty, remove the steering column covers.
  • Disconnect the wiring harness from the ignition switch.
  • Remove the switch and replace it with a new unit, securing it with the appropriate fasteners.
  • Reconnect the battery and test for proper operation.
