I'm posting on this thread rather than starting a new thread . . .

As I have not been running my Rescue Roadster very often, I put on a battery disconnect switch to keep the battery from getting run down. So . . . I switched the battery on today and found the car was in a "no crank / no start" condition. All power came on when you turn the key on but nothing happens when turned to the start position. Also the key fobs did not lock / unlock the doors (both FOBs were inactive).

I had remembered reading somewhere on the forum years ago that if the battery is disconnected and reconnected several times, the car will will think it's being stolen and shut down. To repair / reset this problem, I read to disconnect the RCM and reconnect it.

So . . . I disconnected the RCM and connected up a brand new one that I had in my parts collection. The car started right up and the key fobs were active again.

I know this problem is directly related to disconnecting and reconnecting the battery multiple times over the past several months. Can someone explain exactly what happens with doing that / why the car immobilized itself to a "no crank / no start" condition? Can this problem be avoided while still being able to disconnect / reconnect the batter over time??

Thanks for sharing your experience and expertise . . .

PS - I'm going back out to reconnect the original RCM and see if the car will start normally. I'll update this post shortly about that . . .

I replaced the original RCM and the car was back to a "no crank / no start" condition. So disconnecting / reconnecting the battery multiple times triggered something in the RCM to shut down. Can someone tell me what was shut down in there and how to reset it?
