Symptoms
Owners of certain 2021-2022 Toyota vehicles may experience an inability to complete firmware updates for their Data Communication Module (DCM). This issue specifically affects vehicles equipped with LG DCMs.
Diagnosis / Trigger Conditions
The primary reason for the Toyota DCM firmware update failure is often related to the vehicle's account status. This can occur if the vehicle does not have an active account for connected services or if these services were waived during the trial period. Without an active connection or service entitlement, the DCM cannot properly receive and install necessary firmware updates.
Repair Procedure Summary
To address the Toyota DCM firmware update failure, a specific procedure called "Temp DCM Activation" is required. This temporary activation allows the vehicle's Data Communication Module to bypass the account status check, enabling the completion of the firmware update. Technicians will follow detailed steps to enable this temporary activation and ensure the firmware update is successfully installed.
Owner Action
If you own a 2021-2022 Toyota Camry, RAV4, Corolla, Avalon, or Venza and suspect your vehicle is experiencing a DCM firmware update failure, it is recommended to visit your authorized Toyota dealership. The dealership service department has access to the necessary tools and procedures, including the "Temp DCM Activation" process, to resolve this issue.
