Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.
Gather tools: multimeter, socket set, jumper wire, and cleaning tools for terminals.

2. Battery Inspection and Replacement

Check Battery Voltage
- Connect the multimeter to the battery terminals; a healthy battery should read around 12.6 volts or higher.
- If the voltage is below 12.4 volts, proceed to charge or replace the battery.
Clean Battery Terminals
- If corrosion is found, use a wire brush and baking soda solution to clean the terminals.
- Ensure the connections are tight when reattaching the terminals.
Replace Battery (if necessary)
- If the battery is confirmed dead or faulty, remove it using a socket set.
- Replace it with a new battery that matches the specifications (typically a group size 24F for E170).
- Reconnect the battery terminals, starting with the positive terminal first.

3. Starter Motor Check

Bypass the Starter
- Use a jumper wire to connect the positive terminal of the battery to the starter solenoid's terminal.
- Listen for a click or the starter engaging; if it does not engage, the starter may need replacement.
Remove Starter (if faulty)
- Disconnect the negative battery terminal before proceeding.
- Remove the starter bolts using a socket set, disconnect the electrical connectors, and take out the starter.
Install New Starter (if necessary)
- Install the new starter in reverse order, ensuring all connections are secure.
- Torque the starter bolts to manufacturer specifications (typically around 20-25 ft-lbs).
