I am also having the exact same two error codes that do not clear:

B2840 962E CHARGER On Board Charger
P3173 00C0 EV/HEV On Board Charger Sys

My 2012 Leaf with 88k miles throws a fault on the trickle charger and will not charge on it or our L2 First Gen JuiceBox. When I plug it in, it beeps once for the proximity, but no lights illuminate, and the OBC does not make any noise.

The car will still drive, but I am rationing those miles to drive a little every few days so that the car doesn’t sit static indefinitely. We live in Mississippi and the nearest Nissan dealer won’t touch it, and our nearest Leaf dealer hasn’t ever seen anything like this, and is well out of range, even if it had a full charge. The amber EV Warning light on the dash is illuminated, and if I’m being embarrassingly honest, has been for months, but I was too cheap to buy Leaf Spy Pro for my unactivated Android phone until recently.

As I rack my brain for anything that could be related: the charge cord has ran under our garage door for years, and while we have kept a block next to it to keep the door from crushing it, I wonder if it’s related. Originally, I could get the amber EV warning light to go away by plugging it into the Nissan L1 trickle charger, But it eventually would come back after L2 charging. A few months back, after I plugged it in with the L2 charger, I wiggled the cord and it stopped charging and then started again. I don’t believe it’s happened more than once, but remains possible it’s related.

Again, now neither my L2 charger nor the L1 charger that came with the car originally will get more than a proximity beep when plugged into the LEAF.

I am used to working on my ICE vehicles, and feel like the service manuals give me enough information to change out the charger if necessary. My biggest concern is that 400 V is significant, and I have to convince my wife to let me work on it. While I would like to believe that my issues are related to the “diode“ issues others have talked about, it seems like there are more layers to these codes, which might actually necessitate replacing or at least removing the whole charger.

Diagnosis Procedure

INFOID:0000000010120726

DANGER:

Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of

electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are

handled incorrectly. Be sure to follow the correct work procedures when performing inspection and

maintenance.

WARNING:

• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-

ing inspection or maintenance of high voltage system harnesses and parts.

• To prevent the removed service plug from being connected by mistake during the procedure, always

carry it in your pocket or put it in the tool box.

• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses

before beginning work on the high voltage system.

• Clearly identify the persons responsible for high voltage work and ensure that other persons do not

touch the vehicle. When not working, cover high voltage parts with an insulating cover sheet or sim-

ilar item to prevent other persons from contacting them.

• Refer to

EVC-10, «High Voltage Precautions»

.

• Never bring the vehicle into the READY status with the service plug removed unless otherwise

instructed in the Service Manual. A malfunction may occur if this is not observed.

• Erase DTC after the work is completed.

PERFORM SELF-DIAGNOSIS OF VCM

With CONSULT

Perform self-diagnosis of VCM.
Is DTC detected other than P3176?

YES

>> Check the DTC. Refer to

EVC-102, «DTC Index»

.

NO

>> GO TO 2.

2.

PRECONDITIONING

WARNING:

Disconnect high voltage. Refer to

GI-33, «How to Disconnect High Voltage»

.

Check voltage in high voltage circuit. (Check that condenser are discharged.)

1. Lift up the vehicle and remove the Li-ion battery under covers. Refer to

EVB-181, «Exploded View»

.

2. Disconnect high voltage harness connector and PTC heater harness connector from front side of Li-ion

battery. Refer to

EVB-181, «Removal and Installation»

.

3. Measure voltage between high voltage harness connector terminals and PTC heater harness connector

terminals.

DANGER:

Touching high voltage components without using the appropriate protective equipment will

cause electrocution.

CAUTION:

For voltage measurements, use a tester which can measure to 500 V or higher.

>> GO TO 3.

3.

CHECK ELECTRIC COMPRESSOR

1. Disconnect electric compressor high voltage harness connector.

2. Check the short circuit between electric compressor terminals.
