Identifying Upgraded Software ECM/ETM
Upgraded software for the engine control module (ECM) and electronic throttle module (ETM), available during 2006 or later, can be identified. The updated software has the diagnostic number/software number as set out in the table below. The diagnostic number/software number can be read using VIDA/DIAGNOSTICS/NETWORK.
See USA/Canada market
See All markets except USA/Canada
| CAUTION | For the USA/Canada market, with turbocharged and 6-cylinder normally aspirated engines the software of the engine control module (ECM) can be identified using the software number or diagnostic number , depending on the version of the software involved. |
The differences between the first version , which is identified by the software number, and the second version , which is identified by the diagnostic number, include the following
- Improved driveability after engine control module (ECM) reset. The start values for some system adaptations are adjusted to facilitate handling of aged/worn systems/components after diagnostic trouble code deletion or when the control module has been without power.
- Increased hardiness to certain combinations of aging/wear in the system. The work areas for some adaptations are adjusted to better match the aging of certain components.
- Supplements as to which faults are to generate a message to the driver.
- Improved serviceability (diagnostic trouble code generation) for some intermittent faults that generate driveability problems.
The diagnostic number (also known as diagnostic version in VIDA) and the software number can be read out via VIDA/DIAGNOSTICS/NETWORK. The electronic throttle module (ETM) is identified solely by the diagnostic number.
If the diagnostic number/software number is within the following series, it is the latest software downloaded

- Turbocharged and 6-cylinder normally aspirated engines (USA/Canada market): First version, engine control module (ECM) software number 30785203 - 30785240 and electronic throttle module (ETM) diagnostic number 30785388. Second version, engine control module (ECM) diagnostic number 30785372 - 30785378 and electronic throttle module (ETM) diagnostic number 30785388.

General
The engine control module (ECM) diagnoses both internal signals and functions as well as signals and functions from connected components.
Substitute value
For certain types of diagnostic trouble codes (DTCs), the missing signal is replaced with a substitute value so that the system can continue functioning.
