This bulletin details the Techstream ECU flash reprogramming process and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard (CUW). Flash calibration updates can only be applied to the vehicle/ECU combination for which they are intended. ECUs have internal security that will not allow them to be programmed with another ECU?s information. NOTE ECU is a Toyota term used to describe integrated computerized devices responsible for managing the operation of a system or subsystem. For the purposes of this bulletin, the term ?ECU? is used as a generic label for the following SAE J1930 standard references: ? Powertrain Control Module (PCM) ? Engine Control Module (ECM) ?

T-TT-0521-192019-02-19. Service bulletin. ENGINE AND ENGINE COOLING. TT: The current engine active test ?Control the Injection Mode? is not operating as desired when controlling the direct injectors manually on 2GR-FKS engines. When direct injection is started and then stopped using the active test, current ECU logic does not turn off the direct injectors and can cause DTCs P017200, P017500 and P0160300. To avoid this condition, technicians should raise engine RPM when changing back and forth between the Direct Injection and Port Injection active tests. Use the recommended procedure below to avoid this concern while testing injection mode of FKS equipped vehicles. NOTE: If the active test is used multiple times without using this procedure to raise engine RPM, it may be necessary to reset learning values for fuel trim and Air to Fuel ratio before returning vehicle to customer.
