Lexus RX (RX 350L, RX450h) 2016-2024 Repair Manual: Diagnosis System
DIAGNOSIS SYSTEM
DESCRIPTION
(a) When troubleshooting a vehicle with the diagnostic system, the only difference from the usual troubleshooting procedure is connecting the Techstream to the vehicle and reading various data output from the multiplex tilt and telescopic ECU.
The multiplex tilt and telescopic ECU stores DTCs when the ECU detects a malfunction in itself or in its circuits.
To check the DTCs, connect the Techstream to the DLC3 on the vehicle. The Techstream enables the DTCs to be cleared, several actuators to be activated, and the freeze frame data and various forms of steering data to be checked.
