does anyone know if their is a way for the pdm to hold the count of a counter after it has been powered down. for example, i have a loop around counter for an electric ebrake. 0 is disable ebrake, 2 is nothing 3 is apply and 4 is keep button light on. 2 and 4 are holders after a set time or current limit is reached. my issue I'm having is if i apply the ebrake it will hold the button light on and ebrake on. but if i cycle the ignition off and back on the ebrake stay active because with ignition on it cycles the counter to 2 which is an empty holder. but in order to get the light to come on stating the ebrake is still applied you must press the button again and it will move counter to 3 run ebrake calipers and the amp out moving counter to 4 which is a button light on holder. idk if this makes sense to anyone but basically. need pdm to remember counter was last set to position 4 when ignition was cycled off. or for the pdm to run some type of check to see if the ebrake is applied during start up and if so goes to counter 4 if not goes to counter 2. any suggestions would be great thanks.
