Gen 1 p3006 issue need some help

From the search on the internet in regards to this code - the battery has unusual levels and that causes the error.
You need to call DORMAN and see what their service can provide you with the possibility for a RMA return.

 

To save some time, I suggest you read through the Dorman warranty information first.
Here is a link

Notice #5 below. Make sure you have all the data ready before you call.

From the .pdf
1. Check 12v battery under load. Vehicle requires 11.2v during starting to properly power all compute
2. Check to make sure Orange safety disconnect handle is in the locked (vertical) position.
3. Check trouble codes and clear to make sure they are not stored from previous battery
4. Trouble codes P3011-P3029 are battery failure codes and warrant return.
5. Trouble code P3006 without the above codes requires the Delta SOC PID from the data stream. If the
Delta SOC is below 21%, the issue is not battery related, but could be caused by a failed 12v battery
6. Trouble code P3009 has to be set during key on/not ready to be battery related. Check by connecting
scan tool, turn key to on position where instrument panel lights up, but there is no ready light. Clear
codes and wait 30 seconds. If code does not reset in this mode, the P3009 is not related to the
HV battery.

 

The P3006 is a NOT a ground fault. As Chapman points out, P3009 is ground fault. So having nothing to do with the original post.

P3009 means somewhere in the high-voltage path, there is a resistance path to ground. The car puts an AC signal over the high voltage lines and checks to see if it shows up on the car frame, the ground. Getting more than one is bad as it leaves sources:

• Inverter
• Motor Generator (MG1/MG2)

There are high-voltage, resistance testers, MEGER, that can be used to fault isolate where the ground fault exists. But I want to give a third potential source, the HV junction box near the back of the engine. Rare, I remember one person who decided to wash their engine while it was hot. The wash water cooled the box and it sucked in a little water through the vent tube. Once does not a pattern make.

The usual source, 99% of the time, a battery module has leaked from a terminal seal and in damp weather, forms the resistance to trigger the ground fault.

Consider getting a miniVCI to look at the battery module voltages. A leaking module can unbalance the pack leading to a P3009, a more severe problem.

The other source is having a short develop in MG2 from a burnt (aka., burning) winding. With a miniVCI we can look for the symptom, MG2 temperature too high:

• Normal - ICE temp > MG1 temp > MG2 temp
• Failing - ICE temp > MG1 temp < MG2 temp (MG2 is shorted)

Don't set your hair on fire but think about getting a miniVCI to run on a Windows XP (although some have gotten it to run on more recent Windows OS.) We can then see what the Toyota dealer sees and the folks here have a lot of 'lessons learned' experience to help.

No manual in front of me at the moment, but are you sure ground fault isn't P3009?

P3006 was already identified upthread as module-to-module voltage variation, which I think is what I remembered too....

Look to see if "Xhorse" is mentioned as they were the original designers and makers of the cable. Then they got cloned.

Not there. This is why the miniVCI is such a useful tool. You'll be able to read out the 19 module pair voltages and temperatures.

+1 get a complete reading via TIS to check for yourself.

For the Mini VCI:

Option 1 Windows XP or lower: Amazon search for FOTGA Mini VCI $28 with shipping

Option 2 Windows 8 or higher: Ebay: Mini VCI OBD2 Diagnostic Tool Scanner for Toyota Prius C V PHV RAV4 EV Rush T100 | eBay $40

The two above may not work on Toyota's older than 2000, If you have a 1996-1999 car and want to use the TIS then get this last option that would work on all OBD2 systems of the Toyota brand and their subs:
2015 Original Mini VCI Diagnostic Cable for Toyota Lexus Tis Techstream FW 2 0 4 | eBay $60

They all run the latest version of TIS 10.XX.

As far as the ant's nest, if the relay/s are compromised it would be the Inverter Coolant Pump and another code. In the ON position is the pump flowing?

 

Outstanding!

Looking forward to your Data List

 

P3030 = HIgh Voltage Line disconnected/snapped???

WTD? who installed your battery?

Did you or they install a new Bus Bar with sensors? If old one was put back on, one or more of the sensors could be corroded and throwing this code.

Again a TIS report will show which sensor is FAULTY. This is almost a definite source of our P3006 code

 

Under the cover, YES.



That means the replacement battery's bus bar may be defective but your TIS report will confirm it.

 

But before replacing it, prove it with the TIS report, they will not be able to argue it. Especially since you did not open the cover.

Sometimes it happens Brother. Even with factory items, ask me how I know :-(

 

Sometime such things are negotiable.
