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 (Volvo scan tool).

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 (Volvo scan tool). 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  : Engine control module (ECM) diagnostic number 30785129 - 30785132 or 30785667 and electronic throttle module (ETM) 30785387.
• Turbocharged and 6-cylinder normally aspirated engines  :

  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.
