MS43 KV6 (FREELANDER NAS - Physical Details

SM084 - MS43 KV6 (FREELANDER NAS - Diagnostic Capabilities (Read Fault Codes)
Reads the fault code memory. The ECU can self detect around 230 different problems with itself, its wiring and its associated sensors, storing the respective code if it detects any malfunction or reading outside of predefined acceptable limits. Not all stored faults may cause the fault warning lamp to illuminate.

SM084 - MS43 KV6 (FREELANDER NAS - Diagnostic Capabilities (Clear Fault Codes)
This function, first reads the fault code memory to ensure that there are faults to clear, and if there are, it completely erases and clears the fault code memory. Having deleted the faults, it then rechecks the fault memory, to check that it is clear, reporting success, if it is. Failure to clear the fault memory successfully is usually due to the system re-logging the fault the moment the fault memory is clear. This indicates that the fault has not been rectified properly and as far as the system is concerned, still exists. The recheck for successful clearing of the fault code memory may be successfully executed but then the system may re-log the fault shortly after.
