Identifying upgraded software ECM/ETM: Notes
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 All markets except USA/Canada
For the USA/Canada market, with turbocharged 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 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:
- Non-turbo engines , (all markets): Engine control module (ECM) diagnostic number 30785129 - 30785132 or 30785667 and electronic throttle module (ETM) 30785387.
- Turbocharged 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.
- Turbo engines , (all markets except the USA/Canada market): Engine control module (ECM) software number 30785372 - 30785378 and electronic throttle module (ETM) diagnostic number 30785388.
