Technical Description (Comment)

The ETACS-ECU activates the encrypted code register mode according to the following switch signals:

• Key reminder switch
• Hazard warning light switch

If the encrypted code register mode is not set, the relevant input signal circuit or the ETACS-ECU may be defective.

If a transmitter can not be registered although the encrypted code register mode is set, the transmitter or the ETACS-ECU may be defective.
