Explanation
Not all the parameters described need to be implemented in the control module. This varies from system to system.
Frozen values are parameter values that are stored when a diagnostic trouble code (DTC) is stored.

Scheme 14
Measurement range: 0- 653.8 km/h.
The engine control module (ECM) derives wheel speed from the relevant wheel sensor signal.
Extrapolation Counter
Measurement range: 0- 255
The normal value if the car is driven should be 0. The extrapolation counter calculates if the number of wheel speed changes are higher than the number allowed.
If the signal from the wheel sensor is affected by electromagnetic interference, varies too much or is affected by short intermittent open-circuit/short circuits, the control module can interpret it as a speed change and the counter will begin updating. When the control module registers that speed changes are within the permitted values the counter value will reduce again.
Wheel Acceleration
Measurement range: -1.28 - +1.27g
Positive value: acceleration
Negative value: deceleration
The control module derives the wheel acceleration/deceleration from the relevant wheel sensor signal.
The value can vary a great deal depending on the road surface An uneven road gives greater variation.
Vehicle Reference Speed
Measurement range: 0-653.8 km/h
The control module derives the reference speed from all the wheel sensor signals.
Vehicle Speed CAN Signal
Measurement range: 0.60- 653.80 km/h
The control module derives the vehicle speed based on the wheel sensor signal and transmits it over the Control area network (CAN).
The vehicle speed signal which is transmitted over the Control area network (CAN).
The Vehicle Acceleration
Measurement range: -1.28 - +1.27g
Positive value: acceleration
Negative value: deceleration
The control module derives the reference acceleration/deceleration from the relevant wheel sensor signal.

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 appropriate scan tool.
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 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.
