Re: No READY. P1A15 error. Condenser charge timeout.

Thanks for sharing your repair experience. It looks to me that there are 2 legs in that circuit, either of which could cause this problem. One is a real voltage drop in the path involving the photocoupler, FET2 and the bleed resistor. The other is an error (thermally-induced) in the voltage measurem...

Re: No READY. P1A15 error. Condenser charge timeout.

Did yall check the other components in the schematic, such as the photocoupler PC7 and the FET2? What about the value of the resistors in the voltage divider, and all the little capacitors? If the FET2 were slightly turned ON by leakage thru the PC7, then it could pull the voltage down by 8-10 volts...

Re: No READY. P1A15 error. Condenser charge timeout.

Thank you kirq4e for the follow up with your solution. What month was your car built according to the label on the door jam. Or what is the VIN, to search for recall notices. That chip is an op amp made by Analog Devices, AD8677. It is used on the little hybrid board soldered to the main board. The ...

Re: Got the RBS and car with exclamation mark through it errors.

It's a regular 12V battery available at any parts store or wallmert, type 151, same size used in mazda miata. Hot weather may aggravate a weak battery situation. You may be able to chargge it up with a regular 12V battery chargger in order to drive to get a new one. The OEM has fill ports to check a...

Re: Got the RBS and car with exclamation mark through it errors.

Replace your old worn out and weak 12V Aux battery before you do some real damage, such as having it fail during charging and taking out the On-Board Chargger, a very expen$ive item. It may seem to be okay, but they do wear out and losing the 12V is catastrophic in an EV. A gasoline car doesn't matt...

Re: Dash warning beepers

Seems like i had the same concern a couple of years ago, and wrote a post about how to disconnect the key switch and put a jumper in the seat belt switch connector to get rid of that annoying noise. Plus i wrote about pulling out the knee shredders located below the steering wheel. i'll have run a s...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Good point, i didn't have a replacement fuse so made the jumper for test purposes, but probably not a recommended practice. So i thought it should be fixed, but no such luck. i was able to start to READY, and drive the car, but still getting the same DTCs when trying to chargge. The fan and water pu...

Re: Heat Damaged Charger Plug

i recently had the MCU fuse and OBC snubber caps fail in my 2012, and have made repairs with pictures in the troubleshooting thread. But in thinking back to the events before that occurred, i had been using the OEM Level 1 EVSE to chargge my car for about 2 weeks. Usually i use my Level II Blinnk un...

Snubber Cap Solder Repair Pictures

This was my final selection, i used the larger diameter 6kV-rated caps. Cut slots in the walls of the doghouse plastic to route the leads to the PO and NO solder joints from the waffle plate. Coated the inside of the doghouse with liquid electrical tape compound from home depot. Carefully bent the l...
