why does my Genesis G70 make a clicking noise when starting

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, battery terminal cleaner, safety gloves.
• Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection and Replacement

1. Check Battery Connections:

   • Clean any corrosion from battery terminals using a battery terminal cleaner.
   • Ensure the connections are tight and secure.

2. Test Battery Voltage:

   • Reconnect the battery and use a multimeter to measure voltage.
   • If the voltage is below 12.4 volts, replace the battery.

3. Replace the Battery (if necessary):

   • Remove the battery hold-down bracket using a socket set.
   • Disconnect the positive terminal followed by the negative terminal.
   • Remove the old battery and replace it with a new one, ensuring correct polarity.
   • Reconnect the terminals and secure the battery with the hold-down bracket.

3. Starter Motor and Solenoid Repair

1. Inspect and Replace Starter Motor:

   • Locate the starter motor; it is usually found near the engine block.
   • Disconnect the wiring harness from the starter solenoid.
   • Remove the mounting bolts using a socket set and carefully take out the starter motor.
   • Install the new starter motor by reversing the removal steps, ensuring all connections are secure.

2. Check Solenoid Function:

   • If the solenoid is separate, test it using a multimeter for continuity.
   • Replace if faulty, following similar steps as above for disconnection and installation.
