Check Engine or Malfunction Indicator Light (MIL): Indicates the engine computer has set a Diagnostic Trouble Code (DTC). Usually requires diagnosis with a professional scan tool.

Battery/Charging Alert: Indicates voltage level is below normal level and the vehicle's charging system is not functioning properly. Check battery terminals, alternator belt, and battery condition.

Coolant Temp Warning: Indicates temperature has exceeded normal limits. Check coolant level, fan operation, radiator cap, coolant leaks.

Transmission Temperature: Transmission is operating at higher than optimum temperature as transmission fluid is hotter than normal. Check transmission fluid level and engine coolant level.

Oil Pressure Warning: If this light stays lit, it indicates loss of oil pressure. Immediately check oil level and pressure.

Oil Change Reminder: Indicates that oil life has expired. This is monitored by the ECM; the interval can be mileage or a combination of readings taken by the ECM. The reset procedure is listed in the owner's manual. Some vehicles require the use of special tools to reset the light.

Service Vehicle Soon: Typically indicates a lighting or other electrical problem that is controlled by the BCM (body control module). Check all lights (head lights, turn signals, brake lights, and hazard lights). This symbol may also be used to warn driver of a traction control problem, or a communication problem between modules.

TPMS: Indicates the tire pressure monitoring system has found a tire with low air pressure or there may be a sensor malfunction. Check tire pressure. Some vehicles will allow manual reset of TPMS warning light and others will require professional diagnosis. Refer to owner's manual.

Brake System: Indicates one of three possible conditions: parking brake is on; problem with the braking system/brake fluid is low, or ABS problem. Check brake fluid and make sure the parking brake is fully released. If the problem is in the ABS system, it may need a professional diagnosis.

Reduced Power Warning: Indicates Engine Computer has limited engine power output. The ECM has many levels of reduced power depending on what component has failed in its control system. Usually requires diagnosis with a professional scan tool.

ABS Light: Indicates that the Anti-lock Brake computer has set a code and needs professional diagnosis.

Glow Plug (Diesel): On diesel vehicles this light indicates that the engine's glow plugs are warming up and the engine should not be started until this light goes out.
