I have a decent obd scanner (in the $100 range) that was giving the code (p0480 cooling fan 1 control circuit). looked at the service manual for this code and did some trouble shooting. mostly checking connections, checking fuses, relays, etc. the service manual has you check for shorted wires and relays. everything seems pretty normal with. Hopefully this will save you some diagnostics time. this was on warranty, luckily for the customer. always make sure you crimp, solder, and heat shrink your.
Both fans spin when i use the radiator cooling fan pwm duty cycle test. the video below is very short because i couldn't record and use my alfaobd at the same time so i only could record the spin down after hitting "stop" on the test but you will see both fans slowing down. 2. i also tried the "fan 1" and "fan 2" test. they did not work. P0480 is usually caused by a bad fan or a bad fan relay. good luck fixing your jeep grand cherokee! p0480 is a relatively common obdii trouble code. it indicates that your jeep grand cherokee's "cooling fan 1 control circuit" is malfunctioning. it's a generic code, so it has the same meaning for any vehicle made for the 1996 model year and up.

Diagnostic trouble code (dtc) p0480 stands for “fan 1 control circuit.”. dtc p0480 registers when the pcm doesn’t receive the proper amount of voltage from the cooling fan control circuit that should indicate that the fan works properly. this code can be caused by a faulty cooling fan relay, a bad cooling fan, damaged wiring, or a bad.
