* When the "ID Tire Inflation Pressure" data has not changed, reset the tire pressure to the appropriate specified value and
rotate the tire 90 to 270锟斤拷. Then rapidly release the tire pressure and recheck the data.

HEATING / AIR CONDITIONING: AIR CONDITIONING SYSTEM: B1446/46: Air Mix Damper Control Servo Motor Circuit (Driver
Side)
B1446/46 - Air Mix Damper Control Servo Motor Circuit (Driver Side)
DESCRIPTION
The air mix control servo motor sends pulse signals to indicate the damper position to the A/C amplifier. The A/C amplifier activates the motor
(normal or reverse) based on these signals to move the air mix damper (driver side) to any position. As a result, the amount of air passing through the
heater core after passing through the evaporator is adjusted, and the temperature of the air blowing toward the driver side is controlled.
The A/C amplifier communicates with the servo through a communication/driver IC and wiring assembly called the air conditioning harness.
HINT
Confirm that no mechanical problem is present because this DTC can be output when either a damper link or the damper is
