Subject: VIPER 550 ESP problem
Date Posted: August 14, 2002 at 4:30 AM

This happened yesterday, and my car is still stuck at work.  I have a brand new 2002 Toyota Camry with the Viper 550 ESP installed w/ remote start.  I remote started the car on my way out yesterday (because it's so freakin' hot out), disarmed the alarm, entered the car. Accidentally, I inserted the key and began to start the engine (it was already running), I panicked and then hit the brake and then shut off the car.  Now here's the problem, I am still able to remote start the car, and all power works normally, after I insert the key and then step on the brake to disengage the remote start, electric power (AC, lights, radio, clock, windows) shuts off (the car keeps running).  As a result, I can't drive anywhere.  When I try to start the car normally (not using the remote start), it starts fine, but there is no AC, lights, radio, clock, windows. As a result, I still can't drive anywhere.  I have tried everything (I think) to just get the car on the road and I can't. Is this a blown fuse or something? I called the installer and he said since you're car is working and the remote start is working, it must simply be a fuse problem.  I have no idea what it is. Is there anyway to completely disengage the remote start? is it simply a fuse problem?  anybody know about this???   help!!

Try this first.... look at the fuses under the dash and in the engine compartment for any burned fuses. Then go under the driver dash ( if you can not see any burned fuses ) and look for the remote starter unit and find the inline fuse for the system. There will always be two fuses ( about 30 amps each and they are green in color ). Check these fuses...... go to the next step as last resort

  • Try to look under the driver dash area and find the installer remote starter and unplug the harness that is plugged into it. There will be about 3 or 4 on the Viper. I will assume that the starter disable is installed too, so if you do this you may not be able to start the car at all.

The fuses on the power wires of the remote start relay satellite should be 30 amps each?  Mine are only 10....am I missing something?  (550esp also)

Hey suayan1,

From what you describe, you didn't do anything that would normally damage the remote starter nor the car.  It really sounds like an ACC fuse would have blown under the hood. . . but the question is WHY?   The only possible reason would be a current spike whereas the car would have had to feed over the limit of the fuse.  What other accessories do you have?  Do you have a cell phone adapter that plugs into the lighter socket?  I've noticed on some cars that these adapters short out the socket.  I'm really curious as to what might have happened...keep us posted.

Hey cpgoose,

Don't get confused between the fuses that feed the coils of the relays and the fuses that feed the circuits in the car.

Hey Jeff,

BTW it can't be the fuses on the r-starter cause there's acc power with the r-starter but not with the key.

So what should the correct fuses be?  On the 4-relay satellite, there's 2 red power
wires that go to 12v+ in the car.  Both of those have 10amp fuses.  Then there's
a smaller red wire that goes from one relay to another in the satellite, and that's
also 10 amps...are these the correct sizes?

Hey cpgoose,

To be honest...no it's not what's usually there.  The Big Red wires that have the inline fuseholders normally have 30 amp fuses and the small red has 3 amps.  Why they're all 10 amps I don't know.  It doesn't mean that it won't work, it just means that one might blow if the heater is turned up full blast or if the starter motor draws heavily as it ages.  If I were you I'd change it before running into trouble,  and to be on the safe side, change the small red fuse to 3 or 5 amps max.

well, my car is still stuck in the parking lot at work. I could not find any switch to turn off the remote starter/alarm. the car still starts, but without power (i.e. windows, radio, AC, temp guage). I do have aftermarket stereo equipment (head unit, amp, speakers, cd changer). is my only choice but to have it towed to the place i had it installed? will anything else continue to go wrong? i haven't checked fuses yet, but will replacing any possible damaged ones be all that I need?

syayan1:

1.  I apologize for sort-of taking over your post with my own question...I didn't
realize it until now.

2.  I think you blew a fuse, too.  Did you check your fuses like VELOCITY MOTORS said?
Check the ones under the dash (by your feet or knee), and also the ones under the hood.

But like BIG DOG said, there has to be a reason WHY you blew a fuse (if in fact you did).
Do you in fact have other accessories (like the cellphone adapter) like he said?

The other day I blew a fuse and I couldn't tell which one.  My radio, air conditioning,
and a bunch of other things (like you said) didn't work.  I checked all of the fuses under
the dash and under the hood, but they were all ok.  Then I realized that I forgot the
"blower" fuse under the dash.  It looks different from the "blade-type" fuses (like these below):

It's a bigger fuse like this (I couldn't find a picture (or name), but it looks like this from the side):

When I replaced it, everything worked again.  That could be your problem.  But again, there
has to be a reason why it blew.

Hey suayan1,

Before you have it towed anywhere, find out if one of the guys will come out to your car to have a look if it isn't too far away,  most shops would.  Like I said before it isn't the remote starter's fuses that are the problem especially since the BLUE/RED ACC wire in the car is not required for remote starting hence it probably isn't even connected to the remote starter.  It's an ACC fuse under the hood for sure.  It might be that the amp is connected to the ACC line and the volume might have been left wide open when the car was turned off so that when you did the key take-over the instantaneous heavy draw blew the ACC fuse.  Check the cars fuses. . . replace the one that's blown. . . make an appointment to go back to your installer for a check-up.  posted_image

Hey Big Dog,

2 more questions for ya, now that I found that mistake with the fuses:

1:  Do you know what size the wire is (the 2 power, 2 ign, 1 purple remote start, and 1 orange)
from the remote start relay satellite?  Along with the wrong fuses, some of these wires are very
short and I wanted to extend them...and I'm having trouble determining what size they are (12awg?).

2:  Do you know what size fuse goes with the red wire in main harness?  I know there's another wire
that has a fuse in the main harness but I can't remember which one to ask about.  Oh well.

THANKS!

i have checked the fuses in my car and none of them are blown.. are their fuses or relays in the Viper module that could have gone bad? hopefully, since there are no known fuses blown, the problem is isolated to the Viper module. Does anyone know if this can problem can seriously affect the car? Has Viper been known to have defective modules or is it simply the way it was wired that would have caused the short circuit or blown fuse? I just want to make sure that there are no serious damages to the car, the electrical system or the starter.  I don't really know much about how to check the wiring or anything, but I will get the car towed back to the installer for him to check out. Are there any questions I should ask him? or things i should look out for? any more help would be great!

cp goose the red wire in th emain harness gets a 10 amp fuse the white wire in the same harness gets a 15 and the two reds in the relay satelite harness get a 30 amp each  and the small red one gets a 3 amp fuse. the wire's on the satelite is 14 guage i believe.
