About Vehicle Diagnostics

All modern vehicles use onboard sensors to report on the health & status of various vehicle subsystems including engine management. The sensors report to the engine control unit (ECU) , which in turn creates an error code. Some errors will display a warning light on the dashboard but often error codes can only be indicated by using diagnostic equipment.
GMW provides a dealership level diagnostic check and uses the latest diagnostic equipment from Bosch, Snap-on and others to diagnose the cause of the problems and advise what work needs to be done to rectify any issues found.
