Q: ABS Light on

asked by on

My ABS light is on.

Hi. The anti-lock braking system (ABS) is designed to pump the brake system for the driver in the event of a panic stop. This prevents wheel lock ups and helps maintain vehicle control. The ABS system uses a control module and speed sensors to determine the rate of deceleration. If the module determines that a wheel lockup is about to take place, it will pulse the hydraulic modulator. If the module determines there is a problem with the ABS system, or there is a problem with the module internally, the Check Engine Light will be illuminated. Since the problem could be anywhere in the system, I suggest you have a trained mechanic diagnose the ABS Light for you.

Hello there, 8800 is a very high idle. Most vehicles max out at between 6000-7000 RPM. If the vehicle idles at 800 RPM, then this would be considered normal in most cases, unless the idle fluctuates unusually. If the AC...

Q: Will a radiator from a 09 impala fit

The radiator from the 2009 Impala does not cross reference to the 2000 Lumina, probably partly because the 2009 Impala engine is larger and so requires more cooling capacity. Depending on your VIN number, it looks like all model year...
