WARNING: This page is about a different car, the 2025 Lexus RX 350, 2024 Lexus RX 350, and 2023 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM. If the starter signal (STA) is not detected by the ECM when the engine is started, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.
