MSS Uninstall Information

Software Notes

• The system shall not allow premium software to be uninstalled with a "Master" level key.

• Uninstalling premium software does not uninstall the immobilizers. The premium software must be completely uninstalled. If the premium software is not completely uninstalled, then the MSS will be compromised.

• Tornado MSS software may be uninstalled without the "Bouncer" key reader.

• Immobilizers must be uninstalled before the premium software is uninstalled. If the immobilizer is not uninstalled before the premium software is uninstalled, then the immobilizer will cut off fuel injection to the engine.

• If the engine ECM is replaced with the MSS installed, then the MSS immobilizer will be installed automatically onto the new engine ECM. The MSS immobilizer will function the same as with the previous ECM. The engine ECM must be replaced with a blank ECM or an ECM from the factory that has been flashed with the required software. If an ECM is substituted from another application, then the "Immobilizer" will permanently activate. The "Immobilizer" will not allow diesel fuel injection to occur.

• The immobilizer shall require the MSS to be disconnected from the data link or substituted with another MSS in order for it to be reinstalled. The requirement ensures that the immobilizer is not inadvertently reinstalled by a service technician that does not follow the uninstall instructions. The requirement prevents a service technician from inadvertently reinstalling the MSS if the key switch is turned to the ON position before the MSS is uninstalled.

MSS Uninstall

The MSS uninstall is a two-step process. Each uninstall process requires a unique set of passwords.

1. Uninstall the MSS immobilizer(s).
