CHECK THE FAIL-SAFE FOR THE DOUBLE LOCKING SYSTEM

The double lock ECU will set the double locking system to OFF if there is a door in which the system is ON when either of the following conditions is met. When the system is set to OFF, the door enters the ordinary locked state.
1. The ignition switch is ON (key is inserted into the ignition key cylinder). [*1]
2. 550 rpm or more engine revolutions continue for 10 seconds. [*2]
If any of the double lock position switches are not in the UNSET position after the double locking system has been set to OFF, the double lock ECU will try to set the system to OFF again 1 second later (retry function).
HINT:
1. If the double lock position switch does not turn to the UNSET position with activation of the retry function when the ignition switch is ON (key is inserted), the double lock ECU will not try to set the system to OFF any more.
2. If the 550 rpm or more engine revolutions continue for 10 seconds or more when the ignition switch is ON (key is inserted), the double lock ECU will not try to set the system to OFF.
If the double lock ECU judges that a malfunction is caused by the BEAN, the system enters the following states until the ECU determines that the system is normal.
1. When the double lock ECU has not received any BEAN signals for 10 seconds or more:
