I was 4wd last weekend on and an interesting thing happened with my hazard lights. I managed to hit a rock/boulder relatively hard on my passenger side slider. No body damage thanks to steel sliders. However, my hazard lights come on. I figured I must of accidentally turned them on when I bounced over the rock. Then I discovered that the switch was not turned on. I turned the engine off and removed the keys and the hazards stayed on. By know I was getting a little pissed off, so I pulled the fuse(under hood and dash). Stupid hazards still on. I gave up and started 4wd again. After about 30 ft they went off. Just today I removed the hazard fuse(under hood) to see if they would work with the fuse removed and they wouldn't. Is there any impact sensor then automatically turns the hazards on??? By the way I own 95 disco, $G stage III lift and ARB lockers.

Thanks for you help

Let me clarify that the Hazards are working fine now.

You tripped your inertia switch. Fkn pain in the ass - it's happened to me a few times too. Your rover thinks you've gotten into a wreck. AFAIK there is no way to disable this "feature". Cycling the ignition off/on resets it on mine, don't know why it wouldn't on yours.

It happened to me also while driving down a dirt road. Hit some small bumps. At first I didn't think it was the inertia switch cause I believe that shuts off the fuel pump, unlocks the doors and turns on the hazards. Doors were unlocked and hazzards on but truck was still getting gas. Was also making a clicking sound from some where near the clove compartment. I stopped left the engine running and pressed the reset button on the fire wall a couple of times. Still the hazards didn't stop. So I pulled the fuse. No more hazzards but, could still here the clicking which was driving me nuts. Stopped at a store for some water and popped the hood again. This time I read the owners manual. Says to turn the truck off then hit the button then start it. Mean while I have a whole bunch for Jeepers that I had been wheeling with all day giving crap about the hazzards coming on from "going off road".. Clicking stopped put the fuse back in and everthing was fine. Except for wondering why the fuel pump didn't shut off.. Glad it didn't and I hope the part is broken.

My guess: You did not trip the inertia switch, for had you done so, the engine would have stopped, and not restarted until you reset the switch.

Rather, your alarm system tripped, because it is somewhat sensitive. I don't remember the precise way that you reset the system when this happens: It happened to me a few times, and I figured out, eventually, that if I turned the engine off/on without removing key a few times (or some such sequence), the hazard lights turned off.

Problem was cured by replacing the basic alarm box, which resides behind the glove box.

It happened to me also but just going to fast into a mall parking lot. They stayed on for a few minutes and then went off. I had never figured it out till now.

Thanks for the help. Thank goodness the air bags didn't go off. Yes I was 4wd with some j**p buddies and they were giving me crap. The only thing that made it tolerable was a 2001 Hummer went before me and every time he hit a rock his windshield wipers would turn on. By the way Hummers suck for colorado 4x4. I watched one for 45 min. beat itself over rocks that I had it up the first attempt.

Jef the trail I was on is called Spring Creek. It goes from Dumont(25 miles west of Denver on I-70) to Georgetown. Nice trail, but not for stock trucks. Here is a link to a few pictures of the trip. http://mail.coronastreet.net/~sysop/Four_Wheeling/

What size tires you running Eric B. 235/85 or 265/75?

By wisker on Friday, August 03, 2001 - 05:26 am: Edit

Mine did the same, but would not turn off regardless of what I did. It is the alarm. I pulled the relay from the kick pannel under the glove box (brown one). My alarm still works, but the lights don't (can't) flash. Hazards still work too (different circuit). I never put the thing back in. One less thing to worry about.

"Fkn pain in the ass"

That pretty much sums it up. Damn things go off all the time unless you drive like a little old British lady on her way to tea time. I'm always pulling over to put her in park, kill the engine, start back up, and continue on my merry way to Miller time.

By Eric N (Grnrvr) on Friday, August 03, 2001 - 05:38 am: Edit

Mine was the inertia switch.. Once I turned the car off and hit the inertia switch reset button on the fire wall all was fine. You would think that if it was the alarm the horn would be going off as well as the lights.

By Blue Gill (Bluegill) on Friday, August 03, 2001 - 05:39 am: Edit

Eric, did you engine die too, or just the light show and clicking from passenger footwell?

By Eric N (Grnrvr) on Friday, August 03, 2001 - 06:05 am: Edit

lights, clicking, and the doors unlocked...I turned the engine off and then back on again and it didn't stop. I turned the engine off and hit the button started it back up and presto no more lights or clicking. Engine didn't die which is one of the reasons that I didn't think that it was the inertia switch at first. Plus if it was the alarm and it made the lights flash wouldn't that lock the doors instead of unlocking them?

Engine was running fine. I'm going to pull the alarm relay and go beat it over some rocks tomorrow and see what happens. I'm running BFG 265/75/16. I'm considering getting some steel wheels to make my track about 4" wider. Just not sure how much of the fenders I want to chop. Stock aluminum wheels and rocks do not go together, I have a few nasty scratches in mine.

Eric B, have re-geared with 4:10s or are you running stock gears with that tire size? If you are running stock gears how does it ride on the trail.. Engine braking and such?

By Discosaurus on Friday, August 03, 2001 - 06:29 am: Edit

It was *NOT* the alarm, it was the inertia switch. It turns on your hazards and unlocks all the doors. It's supposed to operate if you've had a rollover. I always thought it cut off the fuel pump but my truck has never stopped running when it happens - which it does ALL the time. Drop off a boulder and take a hard hit on the slider - flashers !

You are supposed to be able to reset it by cycling the ignition key slowly several times.

Think of it as a "f**k up warning" when boulder crawling. If you hit something too hard, you get warned and spectators laugh at you. It's sort of like the infamous Disco horn-beep ! It means you're actually working your truck.

I'm still running stock gears. They are a little high for the trail. I have to keep rpm's around 1200. I'm jealous of my j**p friends that have the old strait engine, they can run all day at 500 rpm's. Maybe I'll get 4.11's for christmas.

"It was *NOT* the alarm, it was the inertia switch."

Not so sure about that, MG's explanation on the LRX forum makes more sense:

I think that some times it may be the alarm and other times it may be the inertia switch. Personally, I had to hit the reset button to make it stop so I'm pretty sure it wasn't the alarm. But, who the hell knows. Maybe me hitting the button and it stopping was all just a coincidence.. Don't know don't care.. I'm just glad the clicking stopped. After about an hour I was ready to rip the whole dash out.

""MG's explanation on the LRX forum makes more sense: ""

Except for the automatic door unlocking. Whatever it is, it's pretty common and, as Alex said, "a fkn pain in the ass..."

The inertia switch works in two stages. There are two different levels of "accident" you can get in. The first can happen off-roading or if you hit a big enough pothole. The hazards come on to make you pull over and check to see if you have caused any damage. After you start the car again, they go off. You don't have to lift the bonnet and reset the inertia switch.

The second stage is an actual accident. If it is a big enough hit, the hazards come on, the door locks come up, AND the fuel pump cuts off. This is what the button under the hood is for. You will have to reset the inertia switch if your fuel pump cuts off.

I've never known of anyone to have the full accident stage engage after an off-roading encounter. While the first stage can be pretty sensitive, the second stage is really accurate (as in, it only engages when you actually get in an accident...).

Actually, there is no need to pull over. Just pop it in neutral, turn key off, and start'er up again, put back in drive. Works for me. Still wish I could disable it.

I swear, if my engine ever dies, I'm dropping in a mild Chev 350 and ripping out all the stock electronics, putting them in a cuisart, and shipping the whole damn mess back to Solihull. So there.

This is exactly what happend to me. In town driving. Hit a pot hole the size of a honda civic. Hazard lights come on. The doors were unlocked and remained so. I pull over and kill the truck. Still flashing. Repeat. Still flashing. Press the reset switch on the firewall, still flashing. Drove home and let it set for a couple hours with the battery disconected. Still flashing. That's when I pulled the relay. I never bothered to put it back in. My hazards work and my alarm works (the lights just don't flash). That was about 8 months ago and I've had no problems since. Make of it what you want. Alarm, inertia, whatever. My lights no longer flash and I and I drive it daily.

Ok, so I havn't bought a manual yet. But I had better go ahead and ask.

Please confirm the location of the intertia switch.

I learned about these the hard way on a Ranger years ago. Just a brief where is it.

Thanks,
