No. Mine is simple.

Update !!!
.
As fuse 28 is of interior lights. I checked all the interior lights ( dome light, map lights, trunk light). Not any fault in them. But still there was leakage in current.
.
Can you tell me which other things are connected with fuse 28 besides these interior lights ?
.
Plus i checked that if i disconnect the fuse 28, battery was not discharged its 4th day now.

Is your aftermarket keyless entry also turning on the interior lights when you unlock it?

That maybe an issue if the unit is trying to trigger the door switch, however I have seen the micu get stuck too. Honda HDS can see that.

But in your case you have isolated it to the interior lights, im suspecting your aftermarket install here.

[nawazish.alee]

Dome light only turns on when its switch is in center.
Only ignition key light (around the switch) turn on whenever i unlock the car. And its also not lighting up now because fuse 28 is out. And this is the only thing which i didn't check yet.

Suppose this light is also not at fault. then ? what do you recommend sir.
.
Also is there anything else that is connected to fuse 28? besides these lights ???? Because everything else is function 100%.

Test the BCM/MICU if its recorded an error.

When this security system was put in what circuits was it tied to?

t was a tiny naked wire touching the body insidethe door.

This is impossible as a naked copper live wire will cause a dead short and blow its safety fuse - it can never cause a slow drain.

Most Pakistani lektrishann's feed this story - "current leak hai" - ye dekho taar shaat horahi hai halki see.

[syncview]

you said that you have a security system installed

remove its connection and observe drain

also that sensor on battery negative, remove its connection too and see what happens to the drain

[nawazish.alee]

Actually i have removed the fuse. so i'm all good for now and don't have to worry about it for now.
.
That battery sensor doesn't make any difference to the current leak but its disconnected.
Plus i'm going to do it more professional way all by myself.
.
All the electricians out there, i know not all of them are the same, but i'm very precautions about their way of working. As i now 70% of the electronics how they all works, so i can tell whether someone is looking the problem professionally or trying to shoot the bird blind-foldly. And the result always going the same for all the electricians I have paid visit to...

[nawazish.alee]

Only error i get is LIN communication error which states in the description that battery management sensor is missing/not functioning properly. (No check Engine Light)
.
Security System is Tied to ignition switch and immobilizer system i guess. Because you need both key and the remote to turn the car on. even if you manage to start the car by unlocking with remote and leave it in house and go out? after 3 to 400 meters car will turn off itself (cluster gets off too) unless you get the remote.

[nawazish.alee]

I have somehow managed to get my hands on AllData 10.53...
.
Downloading the data base now. so that can i look where all the wires are going from fuse 28.
.
It only has data till 2014 from 1980.

If your security system switches on any interuor lamp with remote, its spliced to it. Remove that connection and tesr.

such leakage error is very commonly reported at different forums singled out Fuse 28.
actual culprit is after market stuff which is coupled to it. voltage leakage battery drain overnight are very common issue when C (as in chay) class electricians are working over your vehicle. With zero basic knowledge of load distribution.

re-insert the fuse into junction block. during lock down disconnect the security system and test after 24 hours for any significant voltage drop.

Why are you not removing your aftermarket security system to check? The fault is already diagnosed. The radar system is chewing up the battery isn't that already understandable?

[nawazish.alee]

dear senior members, its been 1 week now battery isn't drained.
but when fuse 28 is plugged in, boom... 4 days and battery is down. (green indicator turns white on the battery)..
.
Plus the security system isn't in the wiring of fuse 28.
Security system and all the other functions are working as they should be...
Only interior lights are not coming up because of the fuse.
.
SO i think there is something linked to interior lights which i am not aware of right now and its draining the battery because of constant voltage drop of 0.6mV on fuse 28 which is equal to 55mA according the chart i have attached. Its a 7.5A fuse.
So the total drain become 0.08A. And without fuse 28, drain become 0.03A which i have read on many forums that its nothing to be afraid of unless it exceed 0.05A.

Let's see, the problem nowadays is Corona Virus. We are crying, criticizing and complaining that our government should have invested in plenty of ventilators in case of such epidemic or should have done this or that WITHOUT realising the actual solution is in self isolation at homes and using proper hygiene routine.

Same is the case here

Does the security system switch on the interior lamps?

In honda

The door switches go to micu, which controls the lamps. Positive is directly supplied to the bullbs from a fuse

If you have a 55 ma load, its probably the ignition courtesy lamp or some other small fish bulb.

Thats why the repitition of security system has bren asked over and over again.

Do you know how that security system is wired up?

[Xulfiqar]

Lin bus comm error is your interior bus, stuff like dome lamp, locks, start button etc.

That is also part of your drain,

The lin bus communicates with micu/bcm.

If its showing error in traffic, fix that first.
