What Causes the Dashboard Bulb Warning Light to Illuminate?
1 Answers
The illumination of the dashboard bulb warning light indicates that one of the vehicle's bulbs has failed, prompting the owner to immediately inspect all vehicle lighting. In most cases, replacing the faulty bulb will turn off the warning light. Details about specific indicator lights are as follows: 1. Timing Belt Indicator: Some imported vehicles equipped with timing belts and overhead camshafts typically impose usage limits on the engine timing belt, which must be replaced when due. 2. Exhaust Temperature Warning Light: Modern cars, due to the installation of three-way catalytic converters on the exhaust pipes, experience higher exhaust temperatures. However, excessively high exhaust temperatures can damage the three-way catalytic converter, so such vehicles are equipped with exhaust temperature warning systems. When the exhaust temperature warning light comes on, the driver should immediately reduce speed or stop the vehicle. The warning light will automatically turn off once the exhaust temperature decreases (however, a fused exhaust temperature warning light will remain illuminated if no adjustments or repairs are made). If the exhaust temperature warning light does not turn off, the cause should be identified and the issue resolved before continuing to drive.
