PWM FAN CONTROLER with AC PRESSURE MONITORING for Jeep Jl with a 3.6L engine. 

The module is a standalone option for controling a factory Jeep JL PWM FAN. We curently offer several options of PWM controlers

NO INPUTS. This unit is configured for automatic CANBUS 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%. 

OVER RIDE INPUTS: We offer optional inputs that when activated will over ride the CANBUS 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. 

POSITIVE. This unit is configured for automatic CANBUS 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. 

NEGATIVE. This unit is configured for automatic CANBUS 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. 

POSITIVE-POSITIVE. This unit is configured for automatic CANBUS 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.

NEGATIVE-NEGATIVE. This unit is configured for automatic CANBUSvariable 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.

You can order the module with either a 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 applications, 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.

2018-2023 Jeep JL  with a 3.6 engine With out E Torque

** not tested or confirmed for the 3.6 E Torque **

** Will not work with the 2.0 engine or the 3.0 Diesel engine **

** Never been tested on the factory 392 ** 

NORMAL CANBUS OPERATION:

When the engine is running the PWM fan will run at a low Idle speed (15%). 

When the module reads the engine temp it will command the fan to the desired %.

Fahrenheit 

199 degrees = 30%

205 degrees = 50%

212 degrees = 75%

218+ degrees = 100%
