Freeze Frame Data
HINT:
The VGRS system stores data when a trouble code is set and can be viewed using Techstream.
- FREEZE FRAME DATA OF STEERING CONTROL ECU
- Connect Techstream to the DLC3.
- Turn the engine switch on (IG) and check the freeze frame data by following the prompts on the tester screen.FREEZE FRAME DATA OF STEERING CONTROL ECU
