Description
Dtc b1785 is output when the occupant classification ecu receives a collision detection signal sent by the front occupant classification sensor lh when an accident occurs.
Dtc b1785 is also output when the front seat rh is subjected to a strong impact, even if an actual accident does not occur.
However, when the occupant classification ecu outputs a collision detection signal, even if the vehicle is not in a collision, dtc b1785 can be cleared by performing the zero point calibration and sensitivity check.
Therefore, when dtc b1785 is output, first perform the zero point calibration and sensitivity check.

Inspection procedure
Ok: completed is displayed.
Standard value: 27 to 33 kg (59.52 To 72.75 Lb)
Hint:
First clear dtcs stored in the occupant classification ecu and then in the center airbag sensor.
Ok: dtc b1785 is not output.
Hint:
Dtcs other than dtc b1785 may be output at this time, but they are not related to this check.
Hint:
Perform the inspection using parts from a normal vehicle if possible.
Ok: completed is displayed.

Compressor solenoid circuit (2006/01- )
Description
In this circuit, the compressor receives a refrigerant compression demand
signal from the air conditioning
amplifier. Based on this signal, the compressor changes the degree of
refrigerant compression.

Internal control module random access memory (ram) error
Description
The ecm continuously monitors its own internal memory status, internal
circuits, and output signals
transmitted to the throttle actuator. This self-check ensures that the ecm is
functioning properly. If any
malfunction is detected, the ecm sets the appropriate dtc and illumina ...
