It just merely stops the SID (Saab Information Display) from informing you, the operator, that TWICE(Theft Warning Integrated Central Electronics) unit has detected a problem with the alarm system. What ever is wrong with the alarm system will still be broken. The alarm system may or may not operate as designed at this point. Since you will need the services of a technician with a Tech II anyway, have him/her check for DTCs (Diagnostic Trouble Code) in TWICE. There may or may not be DTCs stored in TWICE's memory. If there are DTCs, you would want to proceed according to the workshop manual. If no DTCs are present, then your most likely culprit is a bad Theft Alarm Siren Module. There are generally 2 modes of failure. One is the internal batteries fail. This was the reason for the campaign on the 1999-2000 models.The module was not designed to have the batteries replace and Saab does not sell spares for them. Their position is service by replacement. Some people have been successful in locating and replacing these batteries, but not all have been successful. You can do a search on the 9-5 bulletin board on www.saabnet.com. The second is an internal short due to water incursion into the module. The module is located in the left front fender well under the liner. You may be able to dry the unit out, but this will only be a temporary fix at best. Good luck, Steve C
