APPLICABLE VEHICLES:
1649600939621.png



Condition:
Due to improper programming of the Data Communication Module (DCM), which provides cellular communication in various situations, including emergencies, the driver and Safety Connect operator may not be able to hear each other’s voices during a Safety Connect call.

Remedy:
Any authorized Toyota dealer will update the DCM software FREE OF CHARGE.

Covered Vehicles:
There are approximately 221,700 vehicles covered by this Special Service Campaign. Approximately 2,400 vehicles involved in this Special Service Campaign were distributed to Puerto Rico.

Owner Letter Mailing Date:
Toyota will begin to notify owners in late-March 2022.

Head Unit Notifications:
Head unit notifications are electronic messages that are displayed in the vehicle’s audio system screen. Customers who receive head unit notification regarding this Special Service Campaign are requested to schedule an appointment with their authorized dealer to have this Special Service Campaign completed.

When these messages are received by the vehicle’s Data Communication Module, the head unit will display a pop-up prompt stating that the vehicle has a new Special Service Campaign. The prompt will contain options to ‘Remind Me’ or to ‘View’ the message. If a customer chooses ‘Remind Me’, the customer can then choose to be reminded again on next trip, in 7 days, or in 30 days. If a customer views and then closes the message, the message will be available in the Notification App if the customer chooses to review it again. If the vehicle’s completion status remains incomplete for a period of 90 days from the message being viewed, the head unit may display a renotification pop-up prompt as an additional reminder to the customer to have this Special Service Campaign completed.

The message will completely clear from the vehicle once the following conditions are met: The Special Service Campaign is completed, the dealer has filed a claim, and the claim is approved by Toyota. Then the message will be cleared at the next clearing cycle, which currently happens daily.

Owners who receive a head unit notification after having this Special Service Campaign completed can be advised to ignore the message. Owners with additional concerns can be directed to the Toyota Brand Engagement Center at 1-888-270-9371 Monday through Friday, 8:00 am to 8:00 pm, Saturday 9:00 am to 7:00 pm Eastern Time.

Salvage Title Vehicles:
Every attempt should be made to complete an open Special Service Campaign when circumstances permit, unless noted otherwise in the SSC dealer letter.

I did not receive a notification regarding this SSC as stated in the above information. My SOS light if out, my mic does not appear in my Nav Search, but I still have remote start. Is this related to the DCM issue effecting this model? Please advise.

My 2019 RAV4 is having problems with DCM not working properly, the mic does not work when talking on the phone, then clock went out/then back on. Took it to a dealership and charged $150 for a diagnostic then told me I needed to spend $1300 for a new DCM, the car is only 4 years old! and this is a vital piece of safety equipment. I filed a complaint with the NHTSA. I researched online and other 2019 RAV4 models are experiencing the same problem. Please help me solve this issue. https://www.carproblemzoo.com/toyota/rav4/2019/electrical-system-problems.php
