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 appropriate scan tool.
See All markets except USA/Canada
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 and the software number can be read out via appropriate scan tool to identify. 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:
- 5-cyl non-turbo engines B5244SG/B5244SG2 (Bifuel) , (all markets excluding USA/Canada): Engine control module (ECM) diagnostic number 31219965 - 31219968 or 30788502 and Electronic throttle module (ETM) diagnostic number 30785387.
- Other 5-cyl non-turbo engines , (all markets): Engine control module (ECM) diagnostic number 30785129 - 30785132 or 30785667 and electronic throttle module (ETM) 30785387.
- 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.
- Turbo engines and 6-cylinder non-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.
