Hi, I'm Nuwan, a new user of Magna as well as AMC. But I have already read many of threads here..

Today I experienced a strange issue with my beloved Magna TL ES 2004.

1) In the morning I changed all 4 standard wheels in to Alloy (with bigger RIM size & low profile tyres)
2) I drove all day nothing happened
3) In the evening I moved passenger front seat to fill some goods at the back seat
4) From that incident onwards my trip computer display only began to show 'S', center locking doesn't work (either manually, using key or remote)...!!!
5) I finally got rid of 'S' code by referring magna club (I selected S for sedan and 3.5 for engine size and now trip computer display is back again.)
6) But centerlocking still not working.., I hear some 'tik tik' sound from somewhere each time I start the car now.

Please advise me, is this an issue with BEM? Will I have to check for connections or is it a more serious issue?
Does this have something to do with changing wheels? May be it's re calibrating or something?
Or is it directly related to circuit board of the car?

Your help is much appreciated.
Thanks guys.......

If your centre display reset by itself, I'd be checking the output of the battery firstly, by way of a multimeter. Low voltage can play games with the electrics in 3rd gens.

Thanks for the reply brother.. But I don't think it's related to battery.. First it's a new battery, second, vehicle starts without any issue (even with player with sub woofers and AC on..)

Plus 1 for low power gremlins...

Changing the wheels has nothing to do with it, pure coincidence.

Possibly the click click is coincidence...

I'd check the light bulb behind the clock for starters...
And reseat the connector...
There is a console removal guide in my ride thread.. (first Page)

And one more question, does the 'S' symbol keep returning...

Thanks for the reply...! I'm so glad that this has nothing to do with my new wheels..!

Light bulb behind the clock is there... Just I can't see the numbers..

'S' symbol never appeared again after I set it to 'S' and then '3.5 L'

Could this still be related to battery?

Just to lighten the thing, previously I had my Air Bags warning light ON after moving the passenger seat... Then I just moved my fingers around BEM connectors under the passenger seat and next time I started problem gone...! That's why I think this is related to loose connection on BEM... Any idea...?

Check the fuse under the bonnet (behind the battery under the cover) in the yellow pop out piece. One of mine was blown and gave me the same grief. I recall it being the "room light" fuse (11).

Dude, I don't know how I got clock out of center locking. sorry bout that...WTF ( SH00T scratches his head)

The SRS light you see isn't BEM related, the airbag in the side of the seat has a plug down under the seat which has a crappy locking mechanism and moving the seat will loosen this connection. Its a reasonably regular issue. And has been bought up here a few times..

Another issue that that has been raised that affect Central locking, is the connectors in the door, if you car is clicking trying to lock it, sounds like the fuse is OK, as it does try ( the clicking sound ) .

For example, my central locking wouldn't lock the Passenger side front door... So I took of the door skin and reconnected the plug a few times and that was all that was required. However depending on where you problem exists, try sitting in the car and try to lock it, you'll see whats going on, if none are working, it may be the connectors to the lock mech in the drivers door...

Thanks for the reply mate...

Oh... Yeah, Now I recall that I tried to change the room light element and that might be the reason for whole situation...!!! (How could I forget that thing...)
Now, I found the fuse thing got it opened.. But don't really know how to check the fuses..! (Sorry for being such a baby) I couldn't even figure out how to get individual fuses out from the fuse box..
Please advise....

Thanks for the reply brother.... (You guys are awesome... Even after discontinuation of Magna, you guys still love the car as much as I do for mine...!)

Actually door is not clicking what so ever... I tried from inside, out side using the remote and using the key as well but center locking doesn't work.. Only drivers door responds.. No clicking sound nothing at all.. Which means no current is going on through the center locking mechanism.. I don't think it's related to mechanical part actually.. What I think is an electrical issue.. 'Shezza's reply gave me a the answer I think, but still I couldn't figure out how to check the fuses.. I think 'dead one fuse' might cause several issues which might not directly related to the fuse function.. (That's where we might literally go crazy scratching our heads...!)

For an example, 'room light' fuse might have gone.. and it has affected 'center locking', 'fuel pump' (I think this because of the 'ticky ticky sound under the dash board) as well as 'power mirror' (just realized that it's also not working) WTF...!

Please advise if that's possible and how to check and change individual fuses....

Wow.. Circumstances have been changed now...!
It's not seeming to be a fuse now..
Because all the damn functions are working.. BUT..
I have to do selection of 'S' and '3.5L' all the time car starts...!!! After it's done all good everything works.. But after car stopped, all functions restore back to NONE (nothing works) then all I can see is 'S' in the display...!
At least I'm relieved that I can temporary fix it when I want to go somewhere.. But I don't think I want to do this all the time, whenever I park.. and without remote locking car looks stupid..

Is this something serious?

Does your interior light still work? If not, replace the fuse in the yellow square in the fuse box under the bonnet. A lot of circuits seem to run off the one fuse. It's an "always on" circuit, it runs the interior light, power seats, memory for the trip computer, etc.

And check the wiring under the passenger seat, assuming it is electric.

My all dear friends... Everything is fine now... You know what I did..
I managed to pull up 'room light' fuse out and replaced it with another same fuse... (Old fuse has been burned obviously)

Center locking, room lite, Time display all back again...!

After all these fuses are not merely responsible for just one thing.. They are for several things...! Good lesson..

I thank all you guys for your time and efforts to help me out.... Especially thanks a lot to SHOOT and Shezza for great tips...!

+1 on changing the interior light globe and blowing that fuse. lol And then scratching your head because of all the seemingly unrelated things that stop working. lol

I got caught out by that, I now take the light right out of it's hole in the roof before I change the globe.

That fuse seems to run a lot of things that have power on when the car is off and the key is out of the ignition.

Then you check the central locking fuse and it seems fine. Wtf?! There is a reason they put the fuse in that yellow pop out compartment. Just got to remember/be bothered to make use of its functionality :)
Good to see you fixed the problem!

Yeah Yeah Max lol Giggity


I actually keep this stock photo just for this question... Its been used a fair bit...

Seen that picture before a couple of times. Your finger is very photogenic. lol

There's not much clearance between the metal of the roof and the contacts in the interior light fitting. Just move the new globe into place incorrectly and you get a little spark, bye-bye fuse in the yellow rectangle.
By the way, the interior light is live all the time, even if you move the switch on it to off. Light only comes on if you complete the earth circuit via the door switches, the switch on the light itself, or by action of the BEM.

Yeah I saw CenterLocking and my brain saw center clock.... We've had an issue with our clock, teach the kid to read time, falling off the wall, and she keeps changing the time...

Anyway enough excuses... Live it up Maxy....

In other news, my finger still looks that good, head, not so much....
