Sleep operation failure of occupant classification ecu
Description During sleep mode, the occupant classification ecu reads the condition of each sensor while the ignition switch is off. In this mode, if the occupant classification ecu detects an internal malfunction, dtc b1796 is output. Inspection procedure Check for dtc T ...

Air inlet damper control servo motor circuit
Description The damper servo (air inlet control) sends pulse signals to indicate the damper position to the air conditioning amplifier. The air conditioning amplifier activates the motor (normal or reverse) based on these signals to move the air inlet control damper to the appropriate pos ...
