I think we got the transmission figured out. You can force the three bar learn sequence by disconnecting the battery while the instrument panel is still illuminated. But that in itself was not sufficient to correct the situation as the shift problem recurred during a test drive. Trying the shift position sequence by itself next did not help. Only by following the three bar learn sequence immediately with the P>R>N>D>+>->D>N>R>P procedure do we seem to have corrected the shifting. Time will tell if the transmission adapts (or I adapt to it I suppose).
But now I seem to have a problem with the ESP light staying on. I stopped by an independent German car mechanic to shut off the air bag light (which was illuminated because the battery had been turned on when the seats were out of the car) and he noted that the ESP code was due to an "implausible brake light condition" according to his device. He reset the code but it reappeared within a mile of leaving the shop. The Invisibrake system required that a secondary brake switch be installed (since the positive battery terminal is switched with this system), which was done by my RV guy. I called Roadmaster about the problem and they said they have seen this before when the secondary switch was not properly adjusted. Essentially, the secondary switch can interfere with the proper return of the brake actuation rod, triggering a a fault which shuts down the ESP and illuminates its light in the dash. (If the ESP is inactive the car does not allow setting of the cruise control among other things).
Anyway, I took a test drive and checked the brake lights several times, always finding them off, but when I pulled into my driveway I put it in Park, opened the door quickly and found that the brake lights did stay on for about 5 seconds. This seems to confirm the Roadmaster diagnosis. I did have my wife actuate the brake several times and could not get it to stick again but even once is enough to suggest the problem.
I have an appointment Monday to get the switch adjusted and will post again if that does not work. I thought this information may be useful for anybody who decides to install an Invisibrake on their Smart Car. Thanks to you who commented and to SCoA for providing this forum.
Is there a way to move this information from the New Members section to the towing forums?
