I have asked the service representative if the water pump runs while the vehicle is charging. He stated no; however, after the warning EV light turned on, the whine was higher both under operation and charging. The same high pitched whine was heard after the car warned us while running and charging. That said, more seriously is that our dealer stated that 2 cars have had their master brake cylinders replaced costing $3000 plus which gives me pause. Is Nissan aware of brake cylinder failures? When probed what was the cause, normal wear and tear by means of brake fluid leakage. Is this a potential class action lawsuit? This is a worrisome situation whereupon statistics of Ford Pinto replacement part versus letting people be killed in accidents was deliberated and decided upon that the latter was the cost accounting method chosen.

I also think that looks like water pump 1, but can not confirm.
Since you say your pump does not make noise, and you did not
mention further diagnostics after viewing the DTC, thought I would
mention steps from the service manual:
1st it says make sure 12 volt battery reads above 11 volts with car off.
Make sure this is the only DTC seen
(it is the value seen by the VCM that causes this DTC).
check fuse 71, which is in the box behind the battery, middle column, bottom
fuse(next fuse up is for water pump 2).
Check the voltage at pin 1 of water pump for 12 volts.
Note: pin 4 is the control pwm in, and pin 3 the out pwm.
I believe that not matching is what causes the DTC.
Though there is a mistake in the service manual here, where
they describe what the pwm signal should look like. On the VCM
pins they describe both in, and out as in, and show the same signal
picture, so hard to tell if they should look alike.
