WARNING LIGHTS

	Engine management warning light indicating the system has picked up a fault, and can only be diagnosed with diagnostic equipment. The vehicle may lack power when the warning light is on, this is sometimes built into the system to get you home or to a garage. The vehicle may be driven while the warning light is on provided the vehicle is running without any misfires, but should be checked out as soon as possible. For a list of fault codes please click on the EOBD fault code link above.
	The anti-lock braking system is a safety system that stops the wheels from locking up and therefore prevents the vehicle from skidding. If the ABS Light comes on it indicates a fault with the Anti-locking Braking System and should be checked over for faults. You can drive the vehicle while the light is on but the ABS may not work and defaults back to normal braking. For a list of fault codes please click on the EOBD fault code link above.
	The Brake Warning Light can be caused by low brake fluid in the system or brakes pads wearing thin. The Brake Fluid level should be checked at once, and topped up, a low fluid level may be due to a leak. The brake system should be checked out as soon as possible. Also make sure the handbrake lever is fully off, as it shares this warning light.
	Traction Control / Anti slip programme is built into the ABS system, but this time it detects if a wheel is spinning due to slippery conditions or driver error. The system will apply pressure to the brake on the wheel or wheels that is spinning. The warning light will show if it detects a fault with the system. It will be displayed along with the ABS light if a fault is picked up. Diagnostic equipment is needed to find and rectify the fault. For a list of fault codes please click on the EOBD fault code link above.
	Electronic Stability Program detects, prevents and recovers the vehicle from skids. It helps the driver from losing control on slippery roads or due to driver error. The warning Light may come on while the system is active. If the light stays on it has picked up a fault and will need diagnostic equipment to diagnose the fault. For a list of fault codes please click on the EOBD fault code link above.
	The Battery Warning Light should come on when you turn the ignition on and go out when the engine is started. If the Battery Light is on while the engine is running it indicates a fault with the charging system and may run the battery flat in a very short time. If the battery light is not coming on when the ignition is switched, it also indicates a fault.
	If the Overheating Warning Light comes on while the engine is running, the engine should be switched off straight away. The water level should be checked when the engine has cooled down. The cooling system should be checked over for any leaks or faults which is causing the engine to overheat. Major engine damage can be caused if you continue to drive with a overheated engine!
	The Oil Warning Light indicates low oil pressure, and can cause major engine damage if the engine is kept running with the Oil light on. The Oil Level should be checked and topped up if low. Do not over fill with oil, click on the OIL GUIDE link above for the correct oil grade for your vehicle. The Oil Level should be kept between the min and max on the dipstick.
	This warning light is for the Diesel Particulate Filter (may be displayed simply as DPF). The Diesel Particulate Filter is designed to remove diesel particulate soot. The warning light will come on to warn you the filter is more than 75% full of soot or the additive tank that some systems use is low on additive. It may be possible to clear the soot by adding a bottle of Forte DPF Cleaner to the fuel and driving over speeds of 40 mph for more than 10 minutes. If this does not clear the light the additive tank may need filling up with special additive. We carry out DPF regeneration using our diagnostic equipment.
	The Air Bag Warning Light indicates a fault with the Supplemental Restraint System, and can only be diagnosed with diagnostic equipment. The vehicle may be driven while the warning light is on, but the aig bag safety system may not work when the light indicates a fault. For fault codes please check out the EOBD fault code library link above and for help with diagnosing air bag faults please visit Aigbag Help.
