THEFT DETERRENT SYSTEM, Diagnostic DTC:B2761

DTC Code	DTC Name
B2761	Intrusion Sensor Internal Circuit Malfunction

DESCRIPTION

The intrusion sensor conducts a self-diagnosis immediately after 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 main body ECU (instrument panel junction block assembly). The ECU then stores this DTC.
