HVAC CONTROL MODULE PROGRAMMING AND SETUP

PROGRAMMING AND SETUP PROCEDURES

Each of the following service procedures may require programming or setup procedures to be performed on the HVAC control module or HVAC actuators.

HVAC Control Module Replacement
If the HVAC manual or HVAC Automatic control modules are replaced, an automatic Re-Calibration of all the actuators will occur. For the best Re-calibration results, start and run the engine for at least one minute after installing the new module. Do not adjust any controls on the HVAC control module during the Re-Calibration procedure. If interrupted, improper HVAC performance may result. No additional procedures are necessary.

HVAC Control Module Reprogramming
The HVAC control module is not programmable. The only HVAC component that is capable of a reprogramming procedure is the Instrument Panel Integration Module (IPM).

Actuator Replacement
If an actuator is replaced, the following procedure must be performed.

Re-calibrating Actuators - Refer To Re-calibrating Actuators In HVAC Systems-manual.

Re-Calibrating Actuators - Refer to Re-Calibrating Actuators in HVAC Systems-Automatic.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• 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.
