NOTICE:

*1:

This data must read valid before proceeding with any steering adjustments. If invalid, perform steering angle sensor initialization procedure, or if VGRS actuator or VGRS ECU has been replaced, perform VGRS system calibration (steering angle adjustment).

HINT:

*2:

When Rec is listed, reset to Unrec by going to the VGRS menu on the intelligent tester, select records clearance, and follow the prompts.
