I replaced the cells already but that did not cure it. Recently with the engine running, I got out the car to get somethig out of the back and opened the hatch, closed it, came back to find the alarm system warning. I am thinking a switch or cabling fault somewhere being disturbed by the rear hatch opening and closing. I should get Vida out to check the specific code.
