• After all, if you sure the engine trouble is finished, the code will be cleared.

All functions are tested, lights, gauges, central display and warning functions. Once the unit is identified as faulty, we then move onto the rebuild stage. Each unit is fully stripped, all common failing components are then replaced with versions that are higher rated than standard. Once the rebuild is complete, we then retest the instrument cluster to ensure it functions in accordance with the manufacturers original specification.

The coming step is to run a introductory examination of all the electrical circuits, connectors, wiring etc for damages similar as becks, erosion, fraudulent legs etc. All of these will have to be repaired or replaced.

Depending on your vehicle you may have a vacuum operated selector or a vacuum solenoid if it's electrically actuated. In the case of the former, a hand held vacuum pump will have to be used to testit.The purpose is to see if the internal stopcock is getting turned by the selector, motor or solenoid. In order to do this, a command can be transferred to the system with scanner or by driving the vehicle under the special conditions that will spark the system. While this is passing keep an eye on the checkup tool data for the result.
