how to troubleshoot the infotainment system on Honda Accord 9th Generation (2013-2017)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and Torx screwdriver.
• Ensure the vehicle is parked on a level surface with the ignition turned off.
• Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery and Connections Inspection

• Use a multimeter to check the battery voltage; it should be around 12.6 volts.
• Inspect battery terminals for corrosion and ensure they are tightly connected.
• If battery voltage is low, charge the battery or replace it if necessary.

3. Software Update

• Connect the OBD-II scanner to the vehicle’s diagnostic port and check for any DTCs.
• If DTCs related to the infotainment system are found, note them for further investigation.
• Visit the manufacturer's website or contact a Honda dealer to find available software updates for the infotainment system.
• Follow the manufacturer’s instructions to install any updates.

4. Wiring Harness Check

• Remove the trim panel surrounding the infotainment system using a flathead screwdriver or trim removal tool.
• Locate the wiring harness connected to the back of the infotainment unit.
• Disconnect the harness and inspect the connectors for signs of damage or corrosion.
• Reconnect the harness securely, ensuring it clicks into place.

5. Component Testing

• Locate the audio amplifier, usually found in the trunk or under a seat, and check its connections.
• Use a multimeter to test the voltage at the amplifier; it should be within spec as per manufacturer guidelines.
• Test each speaker for continuity and functionality; replace any faulty speakers.

6. Factory Reset

• With the ignition on, access the settings menu of the infotainment system.
• Navigate to the “System” settings and find the option for “Factory Reset”.
• Confirm the reset and allow the system to restart. Reconfigure settings as needed.
