DTC B2762 Intrusion Sensor Signal Circuit Malfunction


DESCRIPTION

The intrusion sensor (built into the overhead junction block) conducts self-diagnosis immediately after power is supplied to the sensor (when the theft deterrent system is set).
If a malfunction is detected in the IOUT - IOUT line, the theft warning ECU outputs this DTC.

DTC No.

    Standard resistance:
    Tester Connection
    Specified Condition
    R8-4 (IOUT) - E83-8 (IOUT)
    Below 1 Ω
    R8-7 (GND) - Body ground
    R8-4 (IOUT) or E83-8 (IOUT) - Body ground
    10 kΩ or higher

REPAIR OR REPLACE HARNESS AND CONNECTOR
OK


2.CHECK OVERHEAD JUNCTION BLOCK (OPERATION)
  1. Temporarily replace the overhead junction block (intrusion sensor) with a new or normally functioning one (RAV4_ACA30 RM000001GED00BX.html).

  1. Check for a DTC.

    OK:
    DTC B2762 is not output.
