Product Description

PWM FAN CONTROLER with AC PRESSURE MONITORING

The module is a standalone option for controling a chrysler style PWM fan know as a pentastar fan or a Camaro style PWM fan. This unit will work with a stock JK 3.8 - 3.6 or one with a HEMI swap.

We curently offer several types of PWM controlers

PWM-CAN. This unit is configured for automatic variable fan speed operation. This unit will read the engine coolant temp and AC pressure info from the vehicle CAN BUS.  It will use this information to determine what speed to run the fan. The fan will run at a low idle speed when the module is powered on and the engine is running, as the engine temps or AC pressure increase the fans will be commanded to run at a higher percentage from 10-100%. 

INPUTS: We offer optional inputs that when activated will over ride the CAN base settings and run the fan at a higher speed. These inputs will operate the fan with the engine off as long as the key is in the run position.  These inputs are optional but make it nice to be able to manually turn on the fan to cool down the engine or to test the fan itself. 

PWM-CAN-POS. This unit is configured for automatic variable fan speed operation. This unit is also equiped with 1 "POSITIVE" side input. By applying voltage to input 1 will cause the fan to run at a HIGH speed. 

PWM-CAN-LOW. This unit is configured for automatic variable fan speed operation. This unit is also equiped with 1 NEGATIVE" side input. Grounding input 2  will cause the fan to run at a HIGH speed. 

PWM-CAN-POS-POS. This unit is configured for automatic variable fan speed operation. This unit is also equiped with 2 "POSITIVE" side inputs. By applying voltage to input 1 will cause the fan to run at a MEDIUM speed. By applying voltage to input 2 will run the fan at HIGH speed.

PWM-CAN-LOW-LOW. This unit is configured for automatic variable fan speed operation. This unit is also equiped with 2 NEGATIVE" side inputs. Grounding input 1 will cause the fan to run at a MEDIUM speed. Grounding input 2 will run the fan at HIGH speed.

PWM-CAN-POS-NEG. This unit is configured for automatic variable fan speed operation. This unit is also equiped with a POSITIVE and NEGATIVE input. Grounding input 1 will run the fan at MEDIUM speed and applying power to input 2 will run the fan at HIGH speed. 

You can order the module with either a POSITIVE, NEGATIVE, POSITIVE & NEGATIVE , NEGATIVE-NEGATIVE, POSITIVE-POSITIVE or CAN ONLY

POSITIVE style activate when the input is over 3 volts

NEGATIVE style activate when the input is grounded

The extra inputs can be used to trigger the fan speeds for custom AC operation, manual overide or other applications. Special programing can be done uppon request, If you have a special request please email us before you make a purchase.  Email HERE if you have questions or want special programing 

12-18 Jeep Jks with a 3.6: When you select "3.6" from the drop down menu the controller willl come with a resisitor to wire into the factory PWM circuit so the check engine light does not come on due to the fan not being connected to the ECU any more.
