Honda HR-V: How to Troubleshoot the Audio System

NOTE: Refer to How to Troubleshoot the Navigation System for information about the audio-navigation unit.

How to Recognize Audio unit and Audio-Navigation Unit (Display Audio Type (7-Inch Screen) )

There are two kinds of 7-inch display audio units depending on vehicle model. These units exist as an audio unit (without navigation) and an audio-navigation unit (with navigation), appear the same, but the audio-navigation unit displays a Honda Globe screen after displaying a Honda logo screen every time when you turn the vehicle to the ACCESSORY mode.

If the unit does not displayed any screen according to failure of the unit or the vehicle, remove the unit, and check for connector C (24P) terminal No. 14. If the terminal is using a BLU wire (VSP line), the unit can be recognized as an audio-navigation unit.

Anti-Theft Feature (Display Audio Type (7-inch Screen) or Color Audio Type (5-inch Screen) )

The audio unit has an anti-theft protection circuit. When one of the following occurs, the unit enters the anti-theft mode:

• Disconnecting the 12 volt battery.
• Disconnecting audio unit connector A (24P).
• Removing the No. A2 (70 A) fuse from the 12 volt battery terminal fuse box or the No. B22 (10 A) fuse from the under-hood fuse/relay box.

After the service, reconnect power to the audio unit, and turn the vehicle to the ON mode. There are two ways to exit the anti-theft mode:

• Press and hold the POWER button for at least 2 seconds. The audio unit automatically exits the anti-theft mode. If the audio unit does not exit anti-theft mode, like in cases where a known-good unit was substituted for testing, enter the 5-digit anti-theft code.
• Enter the 5-digit anti-theft code. If the input of code fails 10 times in a row, the screen is locked for 60 minutes.

If the code is unavailable, you can get the code from the iN using the audio unit serial number. The serial number can be found on a label attached to the audio unit

Global Positioning System (GPS) Limitations (Display Audio Type (7-inch Screen) )

The GPS signal is used for the HondaLink 911 function to communicate the customer's vehicle position to the emergency services. The GPS cannot detect the vehicle's position or elevation during the following instances:

• For the first 5 to 10 minutes after reconnecting the 12 volt battery (this process can take as long as 45 minutes).
• When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside parking structures or large trucks.
• When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the vehicle. The GPS antenna requires a clear unobstructed view of the sky.
• When there is no satellite signal output (signal output is sometimes stopped for satellite servicing).
• When the satellite signals are blocked by the operation of some electronic aftermarket accessories including, but not limited to non-OEM in-dash entertainment units (amp, CD players/changers, radar detectors, theft recovery systems, etc.) and cell phones placed near the navigation system.

The accuracy of the GPS is reduced during these instances:

• Metallic window tinting above the GPS antenna.
• When only three or fewer satellite signals are received (Four satellite signals are required for accurate positioning).
• When driving near high tension power lines.
• When the satellite signals are blocked by the operation of some electronic aftermarket accessories including, but not limited to non-OEM in-dash entertainment units (amp, CD players/changers, radar detectors, theft recovery systems, etc.) and cell phones placed near the navigation system.
• When the satellite control centers are experiencing problems.

LCD Unit Limitations (Display Audio Type (7-inch Screen) )

The LCD display built into the audio unit is touch sensitive. Touch the display directly to select items on the screen.

• Heavy gloves, fingernails or pens cannot be used on the touch panel.
• In cold temperatures, the display may stay dark for the first minute until it warms up.
• When the display is too hot because of direct summer sunlight, it remains dark until the temperature drops (you may see an error message displayed stating this fact).
• Fingerprints on the screen may be noticeable. Clean the screen with a soft, damp cloth. You may use a mild cleaner intended for eye glasses or computer screens. To avoid scratching the panel, do not rub too hard or use abrasive cleaners or shop towels.

SD Card Service Precautions (Display Audio Type (7-inch Screen) )

The audio unit and the SD card cannot be substituted separately for testing purposes. You can substitute a combined audio unit and SD card with a known-good combined audio unit and SD card. When the audio unit and the SD card are connected to a vehicle, and powered up for the first time, the audio unit and the SD card go through a mating process where the SD card writes the audio unit's serial number to its memory. The audio unit and the SD card are available separately.

When you get a replacement audio unit, it does not come with an SD card, but the unit is able to mate one time to an SD card. When you connect the audio unit to the SD card and power it up for the first time, the two components are mated. Once the audio unit is mated, it does not accept an SD card that is already mated to another audio unit. It does accept a new SD card.

The SD card is removable from the audio unit. If the audio unit is replaced, install the original SD card into the new audio unit. When you transfer the SD card, the system data, the application program, and all the customer's settings are transferred.

The SD card is able to mate more than once, allowing you to transfer the SD card with the customer's information to a new audio unit. The SD card must mate to a new audio unit. It cannot mate to an audio unit that has been mated to another SD card.

Lever-Locked Connector

Disconnecting

To disconnect the connector, pull the lever (A) while pushing the lock tab (B) down, then pull the connector (C).

Connecting

To connect the connector, push the connector into the connector sleeve (A). As the connector is pressed in, the lever (B) moves to the locked position.

How to Check Error History (Audio DTCs)

NOTE: The audio DTCs cannot be retrieved with the HDS.

The Error History feature is to record intermittent audio issues that occur while the customer is using the system. Sometimes the customer complaint cannot be duplicated. The error history may record the information needed to diagnose the problem. To check the error history:

1. Turn the vehicle to the ON mode

2. At any screen except the HOME screen, press and hold the EJECT button, the POWER button, and the HOME button until the Select Diagnosis Items menu screen is displayed.

NOTE: When HOME screen is displayed, the HOME button illumination goes out, and is hard to check.

Displaying Select Diagnosis Items Menu Screen

3. When the Select Diagnosis Items menu appears, select the Self-Diagnosis Mode

4. When the audio unit has hard error codes, the Error History icon (A) appears yellow.

When no hard error codes are stored, the icon appears gray. To view the errors with their audio DTC, select the Error History icon.

NOTE: The display differs depending on the equipments and specifications.

5. Select the Hard Error icon in the Error History menu.

NOTE: The Soft Error feature is for factory use only.

6. The Hard Error screen displays the following information by selecting the Date Time icon (A):

• The date and time when the error occurred.
• The audio DTC for the error.
• A brief description of the audio DTC.

NOTE: The Save feature is for factory use only.

7. Use the audio DTC Troubleshooting table to troubleshoot the error. Select the Return icon to exit the Error History main menu.

How to Clear Error History

NOTE: The audio DTCs cannot be deleted with the HDS.

8. Select the Clear icon in the Hard Error. The confirmation screen appears.

9. Select the Yes icon. All Hard Error histories are cleared. The system returns to the Error History menu automatically.
