B2916 Lincoln Code - Auxiliary Blend Door Motor Circuits Shorted

Quick Answer

Under normal operation, to rotate the auxiliary temperature blend door actuator clockwise, the Smart Junction Box (SJB) supplies voltage to the auxiliary temperature blend door actuator motors through the circuit and supplies ground through the circuit. Common causes include Faulty Auxiliary Temperature Blend Door Actuator, Auxiliary Temperature Blend Door Actuator harness is open or shorted, Auxiliary Temperature Blend Door Actuator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2916 Lincoln Description

Under normal operation, to rotate the auxiliary temperature blend door actuator clockwise, the Smart Junction Box (SJB) supplies voltage to the auxiliary temperature blend door actuator motors through the circuit and supplies ground through the circuit. To rotate the auxiliary temperature blend door actuator counterclockwise, the SJB reverses the voltage and ground circuits.
The auxiliary temperature blend door actuator feedback resistor is supplied a ground from the SJB through the circuit and a 5-volt reference voltage on a circuit. The SJB reads the voltage on the auxiliary temperature blend door actuator feedback circuit to determine the auxiliary temperature blend door actuator position by the position of the actuator feedback resistor wiper arm.
