WARNING: This page is about a different car, the 2024 Lexus TX 500h. However, it is still accessible from the selected car via links, so may be relevant.
When communication between the TCM and No. 2 skid control ECU (brake actuator assembly) is not possible, the TCM judges that there is a CAN communication error, the MIL is illuminated and a DTC is stored.
