B27a1 Scion Description

The Certification ECU (Smart Key ECU Assembly) generates a request signal and sends it to the electrical key oscillator built into the front door outside handle assembly (for driver side) at 0.25-second intervals. To detect a key near the driver door, the front door outside handle assembly (for driver side) creates a detection area with a radius of approximately 1.0 m (3.28 ft.) from the driver door at 0.25-second intervals.
The Diagnostic Trouble Code (DTC) B27A1 is detected by the Certification ECU (Smart Key ECU Assembly) if an open circuit is detected between the Certification ECU (Smart Key ECU Assembly) and front door outside handle assembly (for driver side) terminals.
