Unfortunately, but Nintendo's Error Code Lookup for the 162-3185 error code only suggests contacting them, while it can't find the 150-3352 error code and only offer standard tips that might help, sorry.
So perhaps you might want to give a call to Nintendo's 1-800-255-3700 (6 am ~ 7 pm Pacific, everyday) Customer Service number, and one of the service representatives can do some over the phone troubleshooting to determine exactly what the problem(s) might be, and then talk you through any needed steps to correct this.
