Engine or Transmission Electronics Fault Indicator Symbols

Engine or Transmission Fault

This is an Engine or Transmission Electronics Fault Indicator symbol. Another catch-all symbol, the car with a wrench or spanner in it – which looks like a half moon on a pole – points to a problem with the engine or transmission electronics. The vehicle may default to an emergency operation mode, which provides an opportunity to bring it to your dealer or qualified service center under its own power, albeit likely reduced.

• But first, are you sure this is your symbol?? If yes, then read on below.
• Otherwise you can return to our main Picture Symbols page and scan again!

The symbol showing a vehicle with a wrench or spanner inside it is also used as an electronics fault warning. However, some manufacturers use the very same symbol as a service reminder only. If the vehicle is operating properly, and its been a long time since its last oil service, this may be the only issue. Consult your owners manual to be sure and click here for more.

This symbol is used as an Engine Electronics Fault Indicator only. It is seen as a rectangle with a wavy or ragged line inside. Whether or not any change in the vehicle operation is seen, the fault should be checked out by a good service shop as soon as possible.

Note that with either symbol, an issue with electronics can sometimes be resolved be shutting the vehicle down and restarting. Its worth a shot…

The symbol may also indicate a fault in the vehicle’s immobilizer system electronics or fuel filter issues, which will also require a qualified service center to repair. In effect, this symbol is a Check Engine Light, but some manufacturers use it to separate emissions issues (Check Engine) from the others noted here (Engine Fault).
