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 under USA/Canada market .

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:

• 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.
