CONDITION
Some customers may encounter 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 if 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 with 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.

RECOMMENDATIONS



o Confirm if phone has been tested for phone compatibility by going to TIS homepage and
Clicking on Toyota 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.
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 steps are
recommended before handset replacement. The customer should do this themselves as
this will cause their customizations/network connections to be lost.
o For iOS 7.0 and later, the customer can go to Settings, General, Reset. Choose “Reset
all Settings”
o For most Android devices running 6.0 and later the customer can go to Settings, Backup
and reset, “Reset settings”. For older devices which do not have this option you will
have to skip this step.
o For Samsung phones go to Settings, General Management, Reset, then “Reset
Settings”.
If the condition continues to occur only with the customer’s phone, then the only step left before
handset replacement is full system reset. The customer should do this themselves as it will
cause data full loss on both Android and Apple devices. Customer should first backup
their phone and data before proceeding.
o For iOS 8.0 and later, the customer can go to Settings, General, Reset. Choose “Erase
all Content and Settings”
o For most Android phones, the customer can go to Settings, Backup and reset, “Factory
data reset”.
o For newer Samsung phones the settings screen is divided into Tabs. The customer can
go to Settings, scroll right over to the Personal tab, choose Backup and reset, then
“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.
