CONDITION
Customer complains of Bluetooth connectivity concerns such as:
Difficulty to pair the phone
Intermittent Bluetooth failure to connect to the vehicle when first turning on the vehicle.
Various Bluetooth Audio functions are no longer functioning with customer’s phone such as
ability to change the track using the steering wheel controls.
These concerns can be caused by changes made on the customer’s phone. Make sure to inquire with
the customer if the connectivity concerns occurred after receiving an operating system update on their
phone or they have restored their phone data/settings recently.
RECOMMENDATIONS
Check for Tech Tips and TSBs which may address certain Bluetooth concerns with the
vehicle’s multimedia system.
Confirm known good phone in customer’s vehicle. If known good phone experiences the same
condition the vehicle system should be diagnosed using the vehicle’s repair manual.
If known good phone does not experience the condition in the customer’s vehicle no repair
should be attempted to the vehicle. The following steps can be performed to resolve the most
common phone side issues.
o Confirm if phone has been tested for phone compatibility by going to TIS homepage and
Clicking on Lexus
Bluetooth Compatibility Information link under Service Resources. If
the phone did not pass compatibility testing for the customer’s concern please explain
the phone’s limitation to the customer.
o Disable and re-enable Bluetooth on the phone.

Applicability
All Vehicles Equipped with Bluetooth
RECOMMENDATIONS
o Perform “Delete all personal data” on navigation/display audio equipped vehicles.
o Delete all Bluetooth paired devices on the customer’s phone.
o Soft reset customer’s phone or pull the battery out of the phone.
If the condition continues to occur only with the customer’s phone then the next step is
recommended before handset replacement. The customer should do this themselves as it
will cause data loss on Android and full system reset on Apple devices. Customer
should first backup their phone and data before proceeding.
For iOS 7.0 and later, the customer can go to Settings, General, Choose “Reset all Settings”
For most Android phones, the customer can go to Settings, Backup and reset, “Factory data
reset”.
Customer should first try Bluetooth operation before restoring their phone. If Bluetooth issues
are resolved then some software setting or program was causing the concern. If condition is
not resolved then the customer should contact the phone carrier or phone manufacturer for
support.
