Warning Lights

Is your vehicle’s amber Engine Management warning light (EML) on?

Is there a red Malfunction Indicator Lamp (MIL) on or a fault with your glow plug coil light? Auto Experts Medway in Chatham can code read your vehicle’s ECU. We are based in the centre of the Medway towns and can check your engine’s bulb or light faults.

EML Explained:

An Engine Management Light (EML) or Malfunction Indicator Lamp (MIL) is also known as a ‘check engine light’ is a tell tale to indicate a malfunction of a computerised engine management system.

It is found on the instrument panel of most vehicles and when illuminated, it is typically either red or amber in colour. On vehicles equipped with OBD-II (On Board Diagnostics 2) the light has two stages: steady (indicating a minor fault such as a loose gas cap or failing oxygen sensor) and flashing (indicating a severe fault, which could potentially damage the catalytic converter if left uncorrected for an extended period).

Either stage calls for a diagnostic check with a scanner or at least a fault code reader. Call and book your vehicle with Auto Experts Medway, we are based in Chatham in the centre of Medway. We can then carry out some basic checks before conducting some more in depth diagnostic testing.

MIL Explained:

When the Malfunction Indicator Lamp is lit, the engine control unit stores a fault code related to the malfunction. This code can be retrieved with a scan tool and used for further diagnosis.
The malfunction indicator symbol is usually ‘CHECK ENGINE’, ‘SERVICE ENGINE SOON’, or a pictogram of an engine.

EML a history:

The first Engine Management Light warning system appeared in the early 80s along with computerised engine controls. The earliest systems included General Motors (CCC) Computer Command Control system that had a self diagnosis functionality. When the computer detected a fault, it illuminated the MIL.
Up until OBDII, on most cars the MIL could output codes. Two wiring loom plug pins would have to be bridged or jumped. The warning light would then flash the codes.  Some manufacturers, such as Honda, retained this feature even after OBDII.
