Printer Friendly Forum Posts - 08 sienna, remote start, problem

Hi guys,

I installed a remote starter on a Sienna 2008. The van came back with a problem. No DRL. I connected my parking light wire (+) from the remote starter to the green wire above the fuses. I think it called the Body control Module(BCM). I disconnected the parking light wire from the remote starter and started checking for blown fuses and fusible links. I found no fuses blown. Disconnected my starter to see if the drl's would come back.....nothing. I removed the positve post on the battery for 15 min....still found nothing.

I have a really bad feeling that I did something to the bcm.

I was thinking of just wiring up a relay to the headlights, So when he turns to ignition the headlights come on. But I am not sure I want to do that yet.

Any thoughts

Testing is the key

You hooked up positive parking lights? The bcm rests at ground so if you hook up positive lights you blew the fuse in the interior fuseholder(its under the dash). Take your meter and test for THE blown fuse. It will be there. probably under park lights or drl i dont remember exactly which one. The only way I know of on that van is go negative parking lights and pulse the ignition wire. you may not have to pulse the ignition but if the customer is lazy and shuts off their lights with the factory remote or lets the autos time out, the bcm shuts down. Then your neg light input shuts down. Not all remote start units offer this as a programming option, so you may have to make your own circuit.

oh yeah i know cuz i f'd one up myself. Toyota dealer had no clue, found it in 30 seconds.......

The wire I got was green just above the fuses. I also tested this wire, when I turn the parkinglights on this wire turned to 12 volts.

I tested all the fuses under the hood and under the dash. There was only 1 fuse that was blown and it was for the tail lights. I replaced that fuse and the tail lights are working. But still lost on the DRL'S. Looks like I might have to bring it to toyota, maybe if they put it on the computer they can see what is going on. I am starting to think I might have to pay for a BCM.

you said you did the samething? where did you connect the parking lights?

thanks

He's right! You cannot use the green positive wire in the van for lights! You must use a negative off the switch. I remember when that body first came out, very popular. We musta did 20 of them in the first 2 weeks and had no clue you couldn't use a positive light wire(no tech help was out yet). Every one came back with a blown fuse for the lights. That said, every one was fine after we changed the fuse. I would recheck them again(and i mean every fuse, not just light related ones)....

Use negative lights.... GREEN/ black at the switch.

I know about the GREEN/ black wire at switch now, thanks. I will check all the fuses again. Will keep you posted.

thanks to all who replied

It'll be the 10-amp "TAIL" fuse in the fuse box that's under the driver's dash.

It's a special, very small fuse. You can use a regular mini fuse and it'll work fine, just the fusebox cover won't fit back on properly.

Chris read my second post. I found that fuse and replaced it. I got my "TAIL" lights to work again. But my problem is that the DRL'S are not working.

I spent over 2 hours trying to locate EVERY fuse and fuseable links. There was even 2 fuseable links in back of the BCM, there good also. You needed a mirror to see those fuses.

I believe they use the high beam for drl. Are the high beams still working ?

yes high beams are working.

If only we had a instant chat site we can talk directly....I am getting the van in the next 10 min, to check it again.

if you have msn messanger....you can add me, email address : serafinov@hotmail.com

thanks

P.S. I will be taking pics of this van.

That is good, that only leaves 1 thing to check. Look for a small jumper ( could be a fuse), should be located close to the fuses for high beam headlights. Both wires coming off are marked WHITE/ black. Maybe look into owner manual to locate the fuse.

I will try to email u the pdf diagram

slicksam,

Sorry I didn't pay more attention the first time.

So now I understand. You did positive parking lights at first, blew the TAIL fuse, changed to negative parking lights, and replaced the fuse.

The only other idea I have is that on Toyotas, if you apply the parking brake, the DRLs don't come on until after you start the car and release the brake.

Any chance that the parking brake is on? Or that you accidentally shorted out the parking brake wire?

At the parking brake pedal, you should be able to see just one wire there. Test that it's only negative when the parking brake is on.

Are you telling me there is supposed to be a fuse in the empty slot near the battery, if so what happened to the fuse? and what size Amp goes there?

thanks

Testing is the key

Yes, you can put a 15 amp fuse in there and try it out. To disable the drl, you just pull the pin (fuse out ). Maybe it was pulled out by the owner or dealer when it got serviced ?

Another thing I can think of, maybe the owner had HID lamps installed on the high beam, cuz hids don't work on half power.

Stupid question, but is this owner even complaining about his DRLs not working?

Assuming it was my car, that the rest of the lights work fine and there isn't an idiot light illuminated on the dash, I would be happy that they didn't work - AFAIC they aren't good for anything except wasting electricity and shortening bulb life.

Chris , I live in montreal canada where it is mandatory to have daytime running lights working on your car

Gonna check that van in the morning.

Will get back to all of you.

thanks

ahh...didn't catch the location. It makes sense now.

maybe seeing that the relay rest at ground you could have damaged the relay for the lamps that in turn turns the daytimes on

check to see if the parking light wire still rests at gound

Pretty much impossible to do as a parking light positive wire will always show ground when idle due to the bulb filaments...

if you check directech they say do not use positive as it is a relay that rests at ground

do you have a wiring diagram to disprove this theory

you seem to disprove my theory with no theory of your own

how do you know that the parking light relay dosn't also provide ground for the daytime running lights

did you design the circuit

Ok guys here is the conclusion.

This van comes with drl's, but there is a special place for this fuse, which is not marked on the back of the cover of the fuse. Toyota does not put a fuse they put a JUMPER or PIN in its place. I was looking for a blown fuse. So, I put a 10 amp fuse or you can use a jumper cause it is only a ground that needs to continue the flow.

Here is a pic of the place, if this ever happens to any of you in the futur.

I want to give thanks to all who answered and I want to give a BIG THANK YOU TO MOONLITER he supplied me with all the information on this van.

Once again I tip my hat to this website.

Thanks

Sorry, i should have been more specific. I was saying it's impossible to check for ground at the green parking light wire, not the running light relay. All positive parking light wires show ground at rest in all cars nomatter what.

Anyway, glad you solved your problem Slick...
