Diagnostic Information

The diagnostic charts and functional checks are designed in order to locate a malfunctioning circuit or component through a process of logical decisions. The charts are prepared with the requirement that the vehicle functioned correctly at the time of assembly and that there are no multiple faults present.

There is a continuous self-diagnosis on certain control functions. This diagnostic capability is complement by the diagnostic procedures that are contained in this manual. When the control module detects a malfunction, a diagnostic trouble code sets and the Malfunction Indicator Lamp (MIL) illuminates on some applications.
