Limp Home (Override) Procedure By Ignition Key

This procedure allows the unlocking of the EMS by entering the user password via the IG SW, in case the transponder code cannot be read or is unknown after ignition-ON, a valid transponder code must have been received, otherwise the EMS will remain "Locked" and the lamp will start blinking. This can happen through a malfunction of the transponder, the reading device or an unknown transponder code.

The number of IG ON/OFF must coincide with the password.
