Height Control OFF Indicator Light Circuit: Description
WARNING: This page is about a different car, the 2007 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
If the suspension control ECU detects a problem, the height control OFF indicator light comes on while suspending the height control function at the same time. At this time, the suspension control ECU records a DTC. Connect terminal TC and CG of the DLC3 to make the height control OFF indicator light flash and output DTC.
