Diagnostics

Diagnostics

The ECM incorporates On Board Diagnostics (OBD) software that complies with market legislation current at the time of manufacture. During engine operation the ECM performs self test and diagnostic routines to monitor the performance of the engine and the EMS. If a fault is detected the ECM stores a related Diagnostic Trouble Code (DTC, also known as a 'P' code) in a non volatile memory and, for most faults, illuminates the engine SERVICE ENGINE and/or the SERVICE ENGINE SOON warning lamps. Codes are retrieved using TestBook/T4, which communicates with the ECM via an ISO 9141 K line connection from the diagnostic socket.
