how to fix the radio not working in my Toyota Tacoma N300 (2016-Present)

Solution

1. Preparation

• Tools Required: Radio removal tool, socket set, multimeter, OBD-II scanner
• Disconnect the negative battery terminal to prevent electrical shock.
• Gather all necessary tools and parts.

2. Check and Replace Fuses

• Locate the fuse box under the dashboard or in the engine compartment.
• Identify the audio system fuse based on the diagram on the fuse box cover.
• Remove the fuse using a fuse puller or pliers and inspect it for continuity.
• If blown, replace it with a fuse of the same amperage rating.

3. Inspect Wiring Connections

• Remove the radio unit from the dashboard using the radio removal tool.
• Carefully disconnect the wiring harness from the back of the radio.
• Inspect the connectors and wires for any signs of damage or corrosion.
• Reconnect the wiring harness securely and ensure all connections are tight.

4. Test the Radio Unit

• Use a multimeter to check for voltage at the radio's power connector.
• If there is no voltage, trace the wiring back to the fuse box and battery to identify breaks or shorts.
• If voltage is present, the radio unit may be faulty.

5. Replace the Radio Unit (if necessary)

• If the radio unit is confirmed to be faulty, purchase a compatible replacement unit.
• Remove the old radio unit completely by disconnecting all wiring.
• Install the new radio unit by connecting the wiring harness and securing it into the dashboard.
• Reconnect the negative battery terminal.
