Monitor Description
WARNING: This page is about a different car, the 2012 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.
The ECM continuously monitors its main and sub CPUs. This self-check ensures that the ECM is functioning properly. If outputs from the CPUs are different and deviate from the standards, the ECM will illuminate the MIL and set the DTC immediately.
