Abstract
The present invention relates to a method for controlling a TCU fail-safe using an electronic shift lever. A failure state of TCU is verified through CAN BUS (serial communication, or hardware wire) using an electronic shift lever unit, and a parking sprag is forcibly unlocked from a parking gear by pulling an override cable for parking by the an electronic shift lever unit when TCU being in the failure state, so that the implementation of fail-safe according to a failure of TCU is accomplished with higher control stability than using a transmission and without an addition of a component or a change of design.
