Toyota Sienna Radio Flashing
If the radio display screen begins flashing after putting your Toyota Sienna into gear, it is a sign your minivan has a mechanical issue.
Too often, Toyota Sienna owners are clueless as to why their radio is flashing after turning the engine on. It is a warning sign that there is a malfunction with the electrical system. The most common causes for a Toyota Sienna’s radio to begin flashing are a weak battery or corrosion on the battery terminals.
Often, the battery is not generating enough energy for Sienna’s operating system to work efficiently. A service technician can administer a voltmeter test to determine how much life is left in the battery. The test results offer a better read on its working condition.
To begin the voltmeter test, open the hood and place the equipment on both terminals to get a reading.
Also, look at the condition of the battery terminals. Corrosion may have formed on them, which is a fairly common occurrence.
Usually, battery acid leaks out onto the terminals and lessens their ability to provide a consistent electrical current flow throughout the vehicle.
