E65 ? Anyone know what this means?

[Vipermn]

I get E65 in the lower right corner of the BAC display everyt ime I pull the rear brake lever. Anyone know what this means? I have MP4  48v. the word ERROR is not there like it is when I get a 9 or a 2 there..
Anyone?

I just get the error code "1" on mine when either of the brake levers are pulled.

I have no idea what the E65 means, unless it's just to indicate that the brake switches are working correctly without triggering the "ERROR" status.
