Code Reading

VRS has fault code reading equipment that can interrogate the ECU to find engine management faults. Our code reading equipment is capable of code reading a wide range of vehicles.  Once the fault has been identified, VRS would be happy to provide you with a competitive quote for our technicians to rectify the fault.


What are 'fault codes'?
Fault codes are recognised problems or faulty sensors to the EMU (Engine Management Unit), which is an ECU (Electronic Control Unit). The ECU relies on the sensors on your car to make it run at it's optimum performance at all times. When a sensors goes wrong or there is a fault with the engine, the ECU sees this problem and logs the fault code within it's memory. Often the ECU warning light on the dash board may light up, indicating to you that there is a problem.
 

Do all ECU's handle fault codes?
If your engine is fuel injected then it needs a ECU to control the injection timing. If your engine is run on a carburettor, then it has no ECU, hence no fault codes can be logged or read.
