| Title: VARIABLE GEAR RATIO STEERING: VARIABLE GEAR RATIO STEERING SYSTEM: FREEZE FRAME DATA (2008 LX570) | ||
FREEZE FRAME DATA
HINT:
The VGRS system stores data when a trouble code is stored which can be viewed using the Techstream.
1. FREEZE FRAME DATA OF STEERING CONTROL ECU
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG) and check the freeze frame data by following the prompts on the Techstream screen.
