B. ELECTRONIC DIESEL SYSTEM CONTROL MODULE

Some vehicles may be equipped with a EDS control module that places the vehicle in a limp home mode, with no turbocharger boost, resulting in a customer complaint of poor performance. In this control module the parameters for fault code triggering may have been set too narrow. In case of customer complaints of poor performance, a system test should be performed. If no fault in system can be found, a modified control module is available which should be installed.
