Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, jumper cables.
Ensure vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery cable to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Clean terminals with a wire brush if corrosion is present.
- Tighten any loose connections.
Replace Battery (if required):
- Remove the negative cable first, then the positive cable.
- Remove the battery hold-down bracket and lift the battery out.
- Install the new battery (ensure correct polarity) and secure it with the bracket.
- Reconnect the positive cable first, then the negative cable.

3. Starter Motor Testing and Replacement

Test Starter Motor:
- If the battery is good, locate the starter motor.
- Use jumper cables to connect the starter directly to the battery.
Replace Starter Motor (if defective):
- Disconnect the battery (negative terminal).
- Remove wiring harness and bolts securing the starter.
- Lift the starter out and replace with a new unit.
- Reconnect the wiring and secure the starter with bolts.

4. Ignition Switch and Relay Check

Ignition Switch:
- If the issue persists, check the ignition switch for proper function.
- Replace the ignition switch if it fails the continuity test.
Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay (if available) to test functionality.
- Replace the relay if it is found to be faulty.
