Hello, trying to diagnose the All wheel drive issue on my 2023 Honda HRV, rear diff pump is replaced, awd module replaced but still getting the error for rear diff pump motor current is low,C1851-18 1) Confirmed

Motor Circuit Low Current

after replacing the pump the issue didn’t resolved so i took it to honda and they diagnosed and suggested to replace the AWD module which i did and still have the same issue,

i want to find out How much the current amp should be in the rear diff pump motor.

The DTC code for honda hrv 2023

 

You need to test the circuits instead of throwing parts at it. Take it to a shop that does electrical.

 

Read the post and then answer: i mentioned that i took it to Honda dealer and they tested everything that needs to be tested and suggested to replace the module, which i did, in here i am looking to find out the standard amp in the diff pump

 

Most dealers throw parts at cars. Do what you want.

 

• Hi friend, I have the same problem and I've already done everything you did: I changed the oil, the pump motor, and also the AWD module. I'd like to know if you were able to solve this problem.

 

IIRC there is a TSB 23-031on the subject however if the motor was replaced it is likely not the issue.

The DTC also indicates that there may be a communications loss. So I’m with @grcauto on this. You need to check connections end to end.
