Solution
1. Preparation
  • Gather tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is turned off.
  • Disconnect the battery to prevent any electrical shorts.
2. Address Check Engine Light
  • Sub-steps:
    1. Use the OBD-II scanner to read the error codes.
    2. Investigate the specific codes retrieved and research potential fixes.
    3. Clear the error codes and reconnect the battery.
    4. Start the engine and check if the check engine light returns.
3. Inspect Brake System
  • Sub-steps:
    1. Check brake fluid level in the reservoir; top up if low with the manufacturer-recommended fluid.
    2. Inspect brake pads for wear; replace if necessary.
    3. Examine brake lines for leaks or damage; repair or replace as needed.
4. Test Battery and Charging System
  • Sub-steps:
    1. Use a multimeter to check battery voltage (should be around 12.6 volts).
    2. Start the engine and check voltage again (should be between 13.7 to 14.7 volts).
    3. If voltage is low, test the alternator and consider replacing the battery or alternator if faulty.
5. Check ABS System
  • Sub-steps:
    1. Inspect the ABS fuse for continuity; replace if blown.
    2. Check wheel speed sensors for dirt or damage; clean or replace as needed.
    3. Use the OBD-II scanner to check for ABS-specific codes and address accordingly.
