Indications of Jeep Grand Cherokee USB Port Malfunctioning

The USB port is connected to the USB module on the dashboard and used to connect phones or charge electrical gadgets. The USB may sometimes fail to work. Below are scenarios which indicate faultiness in USB ports:

• The USB port fails to read or recognize cables and flash disks inserted into the port. The USB module reads no disk has been inserted, yet you have the gadget plugged in.
• Other users will complain that their gadgets are recognized but not charging. You may notice the port reads and recognizes the gadget but won’t charge it.
• In other scenarios, the USB module will not power on but displays a blank screen on the module.
• The USB media hub may also read unsupported files or documents. Others indicate error reading files.
• Though rare, one might have one port operating while others are not functioning.

These displays indicate a possible failure of the USB port that requires repair. To cover this section, we shall address each problem at a time. Follow the given guidelines for the sequential solutions.

Blown Fuse

The fuse provides overcurrent protection for the USB medium hub system. In case of a power overload, the thin wire in the fuse melts, breaking the circuit; for such, the fuse protects the USB module from an overcurrent supply.

How do you test a fuse to determine if it’s blown?

Perform a fuse test using a digital multimeter following the guidelines below.

• Remove the fuse from the fuse box under the car hood
• Set the multimeter at the measuring point. Make sure it’s reading zero
• With the two terminals exposed, attach the two end terminals of the multimeter and record the reading
• Switch the terminals so that you can take the reverse readings. Record the new reading

How to fix a blown-fuse?

If the reading is the same, your fuse is okay, and you need to progress on the electrical diagnosis of the system or any other possible cause.

The readings will differ or indicate OL on the screen for a blown-fuse. Replace the fuse with its exact spare. Check the serial number, voltage, and current specification to replace it with the correct fuse.

Your USB media will start working without issues if that is the only problem.

Loose Wiring Connection

If you replace the fuse but the USB screen is still blank, you must inspect the wiring connection. Loose connections are mostly a case of joint work.

Cables held together with masking tape have the highest chance of getting loose. Also, check for the terminal connections for corroded terminals and blocked ports.

How to inspect and fix a loose wiring connection?

Start from the battery to the USB module.

Since the battery supplies 12 volts of charge to the fuse, use a voltmeter and inspect the cables for 12V at different instances. If you record 0V at one point, check for a loose or open connection.

For terminal connections, check for corrosion and scrub it off or replace it with new terminal holders. Loose connections are typical for your jeep grand Cherokee using rough roads.

Software Problems

Most radio modules are programmed to serve for a certain period. Others get affected by viruses and foreign files on flash disks and phones.

You will often notice the USB port charging the connected gadgets, but they don’t recognize them or display a blank screen on the module. This indicates that the hardware is okay, but the software has problems.

How to reset/reprogram the software?

If you check for a blown-fuse or loose connection but find none, be sure to reprogram the software. Others may require you to run a few hacks to reset the radio.

• Set your jeep grand Cherokee on ACC mode
• Press the green phone button and voice recognition button together for half a minute
• Assume any voice notes or sounds you get till the 30 seconds are over
• Release the buttons and put the car in OFF mode
• Now open the driver-side door and keep it open for half a minute
• Close the driver’s door and immediately start the vehicle. There you have your USB port reset

Just like a computer, perform a hard reboot of the software using the display volume and navigation buttons.

• Press the volume buttons continuously for five seconds
• Hold the tuner or browser button together for five seconds while pressing the volume buttons
• Release all the buttons after five seconds and start the car. Your USB port will undergo a hard reboot

You can set the module as per your requirements.

Broken USB Port Terminals

USB ports have the right way of inserting any device so that the terminals align without breaking the terminals. There must be a complete connection between the port’s airports and the terminals of the connected gadget.

Failure to properly connect the cables and external disks lead to bent or broken terminals. That translates into an incomplete connection.

You may hear other people mention their port being loose or having intermittent breakdowns and then reconnecting later. This is often common for people using rough roads.

Broken USB cables may lead to your USB port not working since the connection is faulty. Have the suitable cable in the proper condition.

How to fix broken port terminals?

Broken terminals cannot be repaired. The finger-like terminals are closely packed and delicate in design. Once they break, you have to replace them.

For the bent terminals, you can have them aligned, but I would still prefer you replace them. It costs about $5 to purchase a new USB port. Avoid inserting foreign objects into the USB port.
