DTC B2761 Intrusion Sensor Internal Circuit Malfunction


DESCRIPTION

The intrusion sensor (built into the overhead junction block) conducts a self-diagnosis immediately after the power is supplied to the sensor (when the theft deterrent system is set).
If a malfunction is detected in the intrusion wave transmission or wave reception, or the intrusion sensor wave transmission or wave reception circuit, the intrusion sensor sends a signal to the theft warning ECU. The ECU then outputs this DTC.
