SCAN TOOL OUTPUT CONTROLS - HVAC (AUTOMATIC)
| The Enable condition: Key On / Engine Off | ||
|---|---|---|
| Scan Tool Output Control | Additional Menu Selections | Description |
| A/C Request | Output Control | When you select A/C request, this command allows you to turn the A/C Relay On and Off. When the A/C Relay is commanded On, the A/C compressor clutch should be engaged. |
| Air Inlet Door Position | Output Control | When you select Outside, the HVAC control module commands the recirculation actuator toward the outside air position. When you select Recirc, the HVAC control module commands the recirculation actuator toward the recirculation position. This is shown through a command of On and Off. |
| Blower Motor | Output Control | When you select ON, the HVAC control module commands the blower motor relay ON and a command to increase or decrease air. When you select OFF, the HVAC control module commands the blower motor relay OFF. |
| Auxiliary Blower Motor | Output Control | When you select ON, the HVAC control module commands the blower motor relay ON and an increase or decrease of air. When you select OFF, the HVAC control module commands the blower motor relay OFF. |
| Left Temp Door Position | Output Control | When you select Cold, the HVAC control module commands the front air temperature actuator to the full cold position. When you select Hot, the HVAC control module commands the actuator to the full hot position. |
| Auxiliary Air Temp Door | Output Control | When you select Cold, the HVAC control module commands the rear air temperature actuator to the full cold position. When you select Hot, the HVAC control module commands the rear air temperature actuator to the full hot position. |
| Mode Door Position | Output Controls | When you select A/C, the HVAC control module commands the mode actuator to the panel position. When you select Defrost, the HVAC control module commands the actuator to the defrost position. |
| Auxiliary Mode Door Position | Output Controls | When you select A/C, the HVAC control module commands the mode actuator to the panel position. When you select Defrost, the HVAC control module commands the actuator to the defrost position. |
| Passenger Temp Door Position | Output Controls | When you select Cold, the HVAC control module commands the passenger air temperature actuator to the full cold position. When you select Hot, the HVAC control module commands the actuator to the full hot position. |
| Rear Defog Request | Output Controls | The BCM must receive a Rear Defog request from the HVAC control module in order to enable the output control. The BCM de-energizes the Rear Defog Relay located in the I/P BEC when you select OFF. The relay remains de-energized until you select ON. |
| Recalibrate All Motors | Output Control | When you select On, all air temp, and mode actuators have the capability to perform a recalibration. |

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
