Pump solenoid bad or just not hooked back up correctly?

I posted this on the NICO boards yesterday.

(background info at this thread: http://www.nissaninfiniticlub.net/fo...threadid=69549)

I got a Active Suspension code. It gave me five short flashes and then four short flashes. (54?)

I found the codes in the mechanic manual. 54 is "Pump solenoid-2 system is faulty." That's the main pump, right?

I think that my mechanic didn't hook it back up right. It showed no error codes before the engine swap.

Please see my other thread (referenced above) detailing about my recent engine swap.

Does anyone know what could have been hooked up incorrectly when he put the new engine that would make the system give me this code? I have a shop manual but really can't make out what the problem might be.
