I have a 2000 chevy camaro. most of the time my abs inop sign and asr off lights turn on when the car is cold. after i warm it up for a while i can have it turned off by shutting off the engine and mess with the ignition by turning my key from off to power a few times. any body have an idea to what the problem may be?

CHECK FOR CORRECT CODING OF THE MODULE AND EXECUTE THE BASIC SETTINGS OF THE ABS ECU........TEST DRIVE AND THE ASR WILL GO OFF!!!LET ME KNOW...

ASR is your traction control, the reason why you have a surge is that the ASR is calculating how much force to give to each tire based on sensor data, and this takes time. When you turn it off, the acceleration is treated like any other car with out traction control. The 2000-2003 Camaro had one big complaint, a laggy traction control. You could potentially fix this by replacing the computer unit with a faster aftermarket model and changing sensors out with more efficient models, also tuning the engine can help reduce lag time or acceleration delay.

see the diagram and fix it. you can go too. www.aa1car.com
God bless you

this shouldnt stop you from passing emissions, at least not in NY where i am from

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 you 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 to enjoy the feature of the ASR.. ASR=4 by 4

ABS - Anti-lock Brake System.
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.
ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.
For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.


ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.
The ESP system means the Electronic Stability Program. ESP system includes the ABS system.

The ASR and ABS are voltage sensitive, so each time you disconnect them from power, they will reset. To cancel the ASR light, start engine then turn steering wheel full lock to right, then lock to left...ASR should extinguish. ABS light should then go out once you drive above 8 mph for 100yards or so. Until you can have the climate control looked at by a professional, I would locate and remove the fuse for it when you park up. Much better than disconnecting battery.

Believe it or not, this could be a mass airflow issue. The mass airflow can trigger the lights the ASR and the EPC lights. When i gets really cold, the airflow sensor sends signals to the CPU to readjust the air/fuel mixture.

you most likely have a wheel speed sensor not transmitting signal. need to have abs codes scanned. the asr light is related to the abs light same problem causing both to come on

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