Hi, I am new to the "Volvo Club" and this is my first post so hopefully I can get some good tips.

My 1991 740 (automatic,non-turbo) always cranks up with the 'Overdrive Disengaged' and 'SRS' warning lights turned on. As soon as I press the overdrive button both of the lights turn off but I'm not sure if overdrive is actually engaging and also how the SRSystem is related or how it might be involved. Any help would be greatly appreciated!
