Question about 1992 Chevrolet Corvette

1 Answer

My asr light for the three cables under hood comes on.

When i start vehical and idles its perfect. when i turn on my a/c it seems it decreases in power when placed in drive or reverse. when stopped at a light i usually put the car in neutral so it doesnt die on me. at times the asr light will come on. what do i do to correct this problem ? i know that the a/c should increase my ideal speed but it remains the same, which the engine is not holding power. But,once i turn off the a/c it ideals well.

My 2002 dodge intrepid 2.7 has a power surge issue. I hit the gas and the lights go bright but then the gauges on the dash stop working. Hit the gas again and they start working for a second but go off...


When you accelerate the engine it rocks a bit under the hood. A loose/internally broken ground wire/cable under the hood is a possibility. Look for any and all wires/cables under the hood that might be loose. Wiggle all of these wires and don't forget any ground wires coming off the negative battery post. There are, I believe, ground wires at different areas under the hood. You might find your problem with one of these ground wires. The other possibility is at idle not a ton of charge is being generated from the charging system. Above idle an over charging voltage regulator can be the problem. It may be integrated into the PCM or be part of the alternator. A voltage charge test will reveal this. So, there are two possible sources of malfunction. Best of luck. And don't give up, you'll figure it out.

90's Mercedes ASR light on issue


In the 1990's the ASR system was introduced into Mercedes Benz. Traction control was a great feature but now these systems are aging and giving people hard times with the "limp home mode".

First is a simple check. Sometimes the accelerator cable becomes bound or tight. As holding the gas pedal down from the hood while starting will initiate the ASR limp home mode condition back off the adjustment to put just a little slack in the cable. This will allow no tension at start up and allow light not to come on. Lubrication of the cable is a great idea at this age also.

There is also a speed sensor on the front drivers wheel behind the hub that should be removed and cleaned to provide accurate wheel speed and let the system operate correctly. Also in most MB's of thiese years there is another sensor in the rear end that reads rear axle speeds for proper traction control. This unit is better replaced than cleaned due to the high use and heat from exhaust and milage involved.

If you have been to push the gas pedal to start your car there are other issues involved than ASR and you should look into your ignition parts or fuel delivery system.

I hope my tip helps those with this problem.

Mercedes benz s420 series asr problem


Mostly this problem appends on winter time. I f you take your car to the dealership you could throw your money away like many people did and the problem still not solve. I fixed mine definitely by myself and you could do it too. 1- Open the hood, Jack the vehicle. On both front tires you will see a cable that looks like a Rca jack that connect to the brakes but it's bigger than RCA jack. 2- Follow that RCA cable to the hood and on the other end tou will see 2 small white wires that bring power to ASR and ABS system cut those 2 wires and you automatically disable the ASR and you solve the problem. As you know the ASR system is good for snow, it's like a 4 by 4 and you will need it later to drive safely in bad weather when there is snow. What to do next. After cutting the 2 small wires, I put 2 swiches in case I need the ASR in bad weather.One swich for ASR and the other one for ABS. when you cut one wire you connect both ends to the swich and you do the same for the second wire that you cut. The only one thing you will see is the ASR and ABS light will turn on on the dash. When driving in bad weather, open the hood and turn on the swich

It will not start or will not come out of park no lights work nothing works all it does is ding when you have the door open and key in the ignition


Sounds like the ASR Relay is blown. This is a relay that trips when the car detects an issue and will blow to prevent further damage. This relay is a black box under the hood. Check manual for ASR numbered location. It happened to my dodge neon once and sure enough I had a short in a wire and tripped the ASR. Hope this helps.

1995 mercedes benz S 600, ASR came on and the vehicle won't climb up the driveway, no power , no code , what's the fix


I had a similair problem on my 600SEL 93, I read many articles and they were all bad news. When I checked the transmission fluid, I found out it was under a lot of pressure but the level was fine. After that the problem was gone.

The asr light is on and the car does not


the o2 senser would not cause the a.s.r. light to come on-there is only 2 things that the engine module and the a.s.r. module have in common. 1 is the e.a. actuater(throttle) and 2 is the base module. most likley either your acuater has to be resynchronized or the actuater itself is bad. have codes pulled from your h.f.m.,a.s.r.,e.a-i.s.c.-c.c modules and see what the codes say. You will probably find that they say e.a. actuater module is defective. the pig tail connecters go bad and they need to be replaced just be glad you do not have a 600 series because they cost about 1200 a piece and the v12 have 2 of them. If it is defective and you cannot resynchronize it there is a company that rebuilds them for about 1/3 the cost of a new one- good luck

Just had ac repairs done on 1994 Mercedes 500SL. After I picked it up from shop, the ASR system is active, and by the time I got it home, the CHECK ENGINE light is on, too. Any suggestions?


turn off car and unscrew the throttle cable a little bit then start it up again. ASR is finicky if it feels pedal is being depressed on startup it goes into "limp home" mode.
Have you had your engine upper and lower wiring harness replaced? From 1991-1995 MB was forced to use a biodegradable insulation that went bad under the hood due to engine heat.

On a 1995 S500 Mercedes , ASR light keeps coming on


yes they can but unlikely-more likely a bad over voltage relay(powers up idle speed computer) or wire harness-your vehicle is probably a hfm type fuel injection they changed from lh that year. find out if it is lh check the fuses in the base module located in the passenger side of the engine compartment under a cover held in by 4mm allen head bolts-alot of times these control units have intermittent contact with there connectors. asr stands for acceleration slip regulation-both isc and asr communicate via can system to monitor throttle position- ea isc cc-idle speed cruise control and electronic actuater(throttle)-hopefully i have helped

Passat 200, intermittently break/ABS/ASR/STOP lights come ON


Try carefully topping up the brake fluid, this can happen when the level falls as the pads wear down especially when cornering
