Diagnostic Function

The door locking/unlocking code is automatically updated every time the doors are locked (rolling code). ETACS-ECU sets DTC No. B1A08, B1A09, B1A0A, B1A0B, B1A0C, B1A0D, B1A0E, or B1A0F when it receives wrong signal (rolling code out of synchronization) from the transmitter.

NOTE: When the system is corrected by the keyless entry operation, the diagnostic trouble code will be set as "historic fault."
