BECM DIRECT MEMORY

Although there is already a Module (SM022) which provides full diagnostic access to the BECM (Body Electric Control Module) fitted only to the P38 Range Rover (1995 to 2002 Model). There are a number of core pieces of information that the BECM is by design, unable to reveal through the normal diagnostic connection under the control of a one time usage software lock, and also the ability to change some others. This limitation effectively prevents re usage of salvage or otherwise used BECMs as well as trial substitution. It also forces replacement of the BECM in many circumstances when there is actually nothing wrong with it. Despite high development costs, and expectations of low volumes of sales, we have produced this module which allows for direct connection of a Vehicle server to the Microprocessor of the BECM and thereby direct read and write access to all stored memory in it. Besides offering a full memory save as Hexadecimal in a HTML page capabilities as well as the ability to re load and write pages back, which can be handy for those wanting to experiment with swapping bits round, this module also provides a settings page identical to the SM022 one except all of the previously empty boxes such as EKA (Emergency Key Access) code and the Fob Code which is used to validate the correct remote key fob are now populated. In addition it is now also possible to alter previously read only values such as Odometer (Miles / Kilometres travelled) and VIN numbers. Naturally of course the one time lock function can also be reversed. In addition the State of both the Alarm and the EKA lockout delay can be read and altered which is very useful as in an Armed or EKA locked out BECM there is no way to be able to communicate with it through the diagnostic connection and if there is no way to disarm the BECM it is otherwise a catch 22 situation which is usually circumvented only by replacement with a new BECM.

For security purposes the help pages themselves are not included here and on the Vehicle explorer system are only installed on correctly licensed systems. The instructions detail how to remove the BECM from the vehicle and dismantle it to gain access to the logic board. There are two versions of the board and two different types of processor and the instructions include step by step pictorial explanations on how to connect the Brown CPU lead to the board for both versions. Please note that the software automatically detects the processor version fitted and handles their differences transparently to the user.
