Code 2585 park not working

You very well could have a couple of faulty relays 45 & 46 in the underhood fuse / relay box . Could also have DTC'S - diagnostic trouble code's stored in the BCM - body control module .
DTC B2575 Headlamp Control Circuit
When the body control module (BCM) senses a request for headlamp or daytime running lamp (DRL) illumination, the BCM sends a pulse width modulated (PWM) ground signal to the low beam headlamp driver module through the low beam headlamp driver module control circuit. The low beam headlamp driver module will illuminate the headlamps, adjusting the intensity based on the PWM signal received.
DTC B2585 Park Lamp Control Circuit
When the body control module (BCM) receives a ground signal from the headlamp switch commanding to illuminate the park lamps, the BCM will energize the park lamp relay by grounding the park lamp relay control circuit.
DTC B3802 Park Lamps Request Circuit
The body control module (BCM) monitors the park lamp switch signal circuit and the headlamp switch headlamps on signal circuit in order to determine when the park lamps and headlamps should be illuminated. When the headlamp switch is turned to PARK, the BCM senses that the park lamp switch signal circuit is grounded and the headlamps switch headlamps on signal circuit is open. The BCM will then energize the park lamp relay illuminating the park lamps. When the headlamp switch is turned to HEAD, the BCM senses that the park lamp switch signal circuit and the headlamp switch headlamps on signal circuit are grounded. The BCM will then energize the park lamp relay and headlamp driver module (HDM) illuminating the park lamps and headlamps.
relay # 46 is the HDM headlamp driver module .

The problem is your not familiar with electronic's on modern automobiles . Module controlled systems . BCM - body control modules .
The park lamps consist of the park, tail, marker and license lamps. These lamps are illuminated any time the headlamp switch is in the PARK, ON position, or anytime the body control module (BCM) illuminates the headlamps. The PARK fuse in the fuse block - instrument panel (I/P) supplies voltage to both the coil and switch input side of the park lamp relay. The BCM controls the park lamp relay by grounding the park lamp control circuit energizing the relay.

PCB Relays
This vehicle is equipped with the following PCB mounted relays. High Beam, Low Beam, DRL, Fog Lamp, Park Lamp, Stop Lamp, and Horn relay. They are directly soldered to the underhood fuseblock circuit board. A failure of one of these relays will require the whole underhood fuseblock to be replaced.

Your best bet have a qualified repair shop diagnose the problem . Could have DTC'S - diagnostic trouble codes stored in the BCM For circuit faults .

When the headlamp switch is in the OFF position, the body control module (BCM) receives a ground signal through the headlamp switch OFF circuit and an open signal on the park lamp ON circuit. When the headlamp switch is in the PARK or HEAD position, the BCM receives an open signal through the headlamp switch OFF circuit and a ground signal through the park lamp ON circuit.

DTC B2585 00: Park Lamp Control Circuit - Domestic

Park and dash fuses are good. Replace the light switch. Both of them are power from the light switch.

id bet not. checking fuse by eye is the wrong way,
bad looking sure, are bad but good looking fuses can infact be bad.
we use a voltmeter, it never lies.
the fuse is marked, TAIL, its really parking and all dash illumination lights (dimmable too)
fuses can in fact hair line crack. a fact

if not the fuse, then its the parking system lights failure.
this system is huge, all side lights , front park, tail park
and cab., the FSM factory sevice manual covers this as does
the alldata.com pages, log in and see a real schematic.
see how park happens. from the knob to the lamps.,
some have a relay. on newer cars its works,, one computer tells other to tune on the park relay, be glad that is not your car.
eg: comm errors.

sure, do you have 12vdc to the lamp, in park?
if not work to the source , the relay that the operates that.
alldata.com has the schematic.

fact 1, license plate feed runs off left park.
fact 2, the park relay feed both left and right park fuses and lamps.
so, fuse 7 is left, and fuse 9 is right.
did you only just look at the fuse, and proclaim, good.
or use a voltmeter? or use ohms to test fuse 7, oops
fuses that look good, can be bad. 0 ohms good, infinity is bad.

use volts, is there 12vdc on both sides if fuse 7,>?
yes, then fuse is good, parks turned on.
no, the output side of fuse 7 is 0v. so fuse is blown
if input is dead, the relay is bad, but how can it , if right works, answer.
it cant be bad.
so what is the voltage all the way from the fuse to the lamps.
id bet, (fuse good an voltage good at fuse 2 sides) that the line is open. cut wire, corroded connector.

the BCM turns the relay on, this part works.
so.... its just a break in this simple copper path.

use a voltmeter, it will not lie to you, trust it./

usa car, not Renegade or export car. nor DRL lamps.

fuse, can look good but be bad.
use any ohm meter, to make sure they are good. 0 ohms good.
the car can have park-tail relay. yes, it does have a park relay
that feeds 2 fuses (#7&9) then all lamps left and right.
the BCM controls the relay. body brain.

check voltage at all 4 pins of park relay, and bingo know who is messing up,?
pins 86/87 hot 12v all the time( battery)
87a = ground 0v all times.
30 is relay output, 12v park on.
85 pin is relay coil control. 0v park, 12v not park.
if you have 0v on 85 , in park the BCM is working

there is start.
if a fuse is blown to the BCM, it will mess up

is battery good, check fuseable links under the hood and the light switch itself..

Loosen up the housing and re-tighten, it may not be getting a good ground. Also, turn on the park lights and check for voltage at the fuse. Some auto;s have other fuses that work with other components. You can look in your manual and it may say fuse 14 is for park lights but look at other fuse locations and it will state fuse 25 is for park lights, horn, cig lighter, tow hook up. These are not the right fuse locations, just giving example of how it may be. Good luck

That's two different problems check engine is for engine codes in pcm. The other ?SVS service vehicle soon body control modul if all lights work checks bulbs are they correct other then that you need & scan tool to pull codes for diag If I read complaint correct GOOD LUCK

do the dash board lights come on?
are the relays working? ( in the fuse box usally)
