DTC B1718[12] Anti-theft System Indicator Light Output Circuit Short to Battery (BCM)

1. DTC B1718[12] description

After the doors are locked with the passive entry and start system or keyless entry function, the anti-theft system indicator light illuminates for approximately 10 seconds while the BCM is determining whether the anti-theft system operation conditions are met. After that, if the operation conditions are met, the indicator light starts flashing slowly and the anti-theft system is activated. On the other hand, if the anti-theft system operation conditions are not met, the indicator light flashes rapidly. If the BCM detects a malfunction in the anti-theft system indicator light output circuit, the DTC is set.
