TCS Warning Light Intermittently On after alarm install! Help!

[cyanutopia]

Hi all,

I had a viper alarm (model 5704) with remote start installed today. While driving home, I noticed that after I have been driving for about 10 minutes, the TCS warning light (up at the top of the dash) lights up. ABS warning light is NOT on. If I turn off the car and restart the engine, the light goes away. The car does not feel any different when the light comes on.

Do you think it has to do with the alarm installation and what do you think might be going on? Thanks for your help!!!

more info needed
what year NSX do you have.
how many miles,
do you have bigger than stock rims.
where to taking a corner when the TCS came on?
do you feel the people that installed the alarm know what they are doing? did they tap into something they shouldn't have.

I am sure the TCS and you getting an alarm installed was just pure luck. they prob have nothing to do with each other

Hey, to answer your questions:
1994 NSX, automatic, stock rims, completely stock set up. Checked tire pressures, all to manufacturer specs.
I was driving straight both times without acceleration both times when TCS warning light came on (the one at the top middle, not the one in the middle of the tach). Once TCS warning light came on, it stayed on regardless of stopping/moving/turning until I turned off the ignition. The TCS warning light had never come on prior to alarm installation.
I am hoping the people who installed the alarm knew what they were doing. They took a lot longer than I would've expected (about 10 hours) to install everything from start to finish.

Any thoughts? Thanks

it took 10 hours to install oh my... should take 30 min max. I hope they didn't tap into anything they shouldn't have. lets me think about it more. but let others chime in

after you turned the car off and drove it around again did the light come on? you have to drive it, just starting it up isn't going to pop the light on. the car needs to be moving.

if it was my nsx I would go under the driver side dash and see what kind of wiring they did and rip it out. I had an Alpine that was installed wrong when I first got my NSX it shorted out the main relay and the ignition switch was burn.

some alarm installers don't like to use the rubber grommets the factory has to run wires thru since some of them are really hard to get to. and alarm installers are known to drill new holes in places they shouldn't since there may be a wire harness behind were they are drilling. there are places that the wheel sensors wires go from each wheel to the brain.
if they drilled one you could get a TCS error if the wire they drilled is dangling etc.

I would look under the front of the hood were the siren is follow the wires to the hole they prob drilled. then examine the wires surrounding the hole. trace the wires to the new alarm brain.
then look for the new hood switch they prob installed and trace that back to the new brain.
your looking for any wires that have been accidentlly cut, damaged drilled etc.

start there report back.

Do you have the stock tire sizes (215/45-16 and 245/40-17) or something else (and if so, what are they)?

Sorry to ask again about this, but non-stock tire sizes are the most common reason for the TCS light to come on. And it can happen partway through a set of tires, at any time.

Hey nsxtasy and shawn -

To answer your questions: completely stock wheels/tires. Normal running PSIs.
The light only comes on every few times I drive it - sometimes it doesn't come on at all. It is always off (everything ok) when I first start up the car, then sometimes about 10 minutes after driving, TCS warning light will come on.

I wish I had the know how to see what kind of wiring they did, but I'm definitely not that handy. I am hoping they didn't drill new holes.

Might be time to take it to an expert. Sigh.
