Hello,
After around 68K miles of trouble free operation looks like car is exhibiting a bunch of issues all of a sudden. Now it failing to charge with this error message. Here is the diagnostic details. Thanks to @asavage for the cable and guide on how to use TPD, getting the info was a breeze.
Resistances at the J1772 pins are what described here. I presume that it is a faulty OBC
Background:
Current problems
1. Not charging
2. Cabin heater not working
3. Battery coolant pump error code
4. Found moisture on speed sensor
Questions:
Thanks in advance !

Background:
- Since 2023, Check EV system has been on after it was left with a dead 12v battery for several months. I got annoyed with the 12V battery dying all the time. I had installed a 12V LiTime Lithium battery with battery monitoring. Drove it for about 1 year with the Check EV system on. Drove it for a year thinking it was only related to the dead 12V battery
Current problems
1. Not charging
2. Cabin heater not working
3. Battery coolant pump error code
4. Found moisture on speed sensor
Questions:
I bought a Gen 1 OBC and 2 FWH-50B fuses. Could someone point me to how to program this? After replacing, can this be tested before I put everything back?Decided to fix the pump first per advice below- A few months ago, it started showing much lower range, around the value it would show if the heater was on. Almost appeared as if it thought the heater was on while it was not. Then noticed cabin heater was not working. Looking at the screenshot above, it appears DC-DC is working fine? I guess I need to follow this?
- Any pointers on how to go about fixing the battery coolant pump 2 issue?
- Per advice from @asavage, I checked the speed sensor and there were a few droplets of condensate which appeared colorless. Is a coolant delete a sufficient fix or should the LDU be taken apart to remove the coolant?
Thanks in advance !
