Owners of certain 2021 Toyota vehicles may observe an "Engine Maintenance Required" message displayed in the Multi-Information Display (MID). This warning indicates a potential issue within the engine's cooling system.
Fault Codes / DTCs
When the "Engine Maintenance Required" message appears, the vehicle's diagnostic system may store specific Diagnostic Trouble Codes (DTCs). These codes point to electrical circuit issues within the engine coolant bypass valve.

Diagnosis / Trigger Conditions
To confirm this condition, a technician will first verify if the "Engine Maintenance Required" message is present in the MID. Subsequently, a Health Check will be performed using a diagnostic tool like GTS+ to check for the presence of DTC P268111 or P268115. This confirms the cooling system circuit fault.
Repair Procedure Summary
This Technical Service Bulletin (TSB) outlines the steps to address the "Engine Maintenance Required" message and associated DTCs. The repair involves replacing a specific component in the engine's cooling system, depending on the vehicle model.
