Car in neutral and won't go in PARK

I have a 2009 touring that was running perfect with no problems at all and was parked for a few months where the starting battery completely drained and died. I jumped the car from the front fuse box and it showed an error that the car is not in park and to apply foot brake, the park button lights blinks intermittently and the car will not be in Ready!

I have replaced the battery with original Toyota battery but no help. I have multiple scanners and see these codes (p3102 / c2300 / c0200/ c1310). I have tried to reset but these are current codes so can't!

Meanwhile I have replaced these parts from a running car ... Park button, shifter, Transmission ecu, Pcon relay, Pcon fuse, hev fuse, hybrid battery safety switch, and finally the actuator but still no luck! I have checked all fuses, I have the hv ecu but when I plug it and try to read it it shows me the vin number of the old car .. I have tried to program but was unable to with TIS software. I have tried turnning the actuator to park position manually but the car still sees it in neutral. I can push the car as it is in neutral by default which is strange from safety point of view and have dealt with multiple Prius but never seen this issue.

I've spent 3 weekends and can't figure out what the problem could be on a perfect running car! I will REALLY appreciate help from the community members on this plz!!!


2009 Prius Touring
Mileage: 96k
Error codes: (p3102 / c2300 / c0200/ c1310)
Parts checked and replaced: Pcon fuse, Pcon relay, park switch/button, shifter, transmission ecu, actuator.

 

Hi JC - I'm a part time dealer who loves Priuses .. Have dealt with a lot of them previously. I do not consider myself a mechanic but am handy enough for mediocre things. I bought this car maybe 6 months ago and drove it for a month or so on/off with no problems. I got the car detailed and parked it as it was listed for sale.

This was a running 100% perfect car! Only thing that went wrong was the main battery lost its charge and I had to open the door with key blade and jump it and ran into this issue immediately with the car not going in Ready!

 

I know the battery was dead so after no success with jumping I replaced the battery. Started looking at fuses/relays and then put a scanner and got the codes. Looked deeper and started replacing things hoping to find the root cause.

I love a challenge but this really got me bad looking for expert ideas so I can Fix this car and hoping others can learn from this thread!

 

Hey Guys - thank you for helping I honestly really appreciate it!


P3102:
How do you check for sub codes in TIS? I’ll crank up the laptop and look myself and search the forums for it also.


C2300:
I'll check on the voltage .. i know if you leave the power wire off the actuator i get more errors so didn’t think the power to actuator was the issue or even with Transmission ECU aswell. We did turn the motor of SHIFT CONTROL ACTUATOR (park motor) and was fine but went ahead and replaced it anyway to troubleshoot with no luck. We were able to turn the shift actuator shaft and the car goes in Park manually but even after that it does not go to Ready state.

C0200: I think you're right its just when the car starts running this should go away. There were absolutely no fault lights on the dash when i parked the car.

C1310: ok thanks.



I jumped the car myself and I’m 100% sure i didn’t put the wrong wires. Initially when i jumped it the car alarm went off as soon as i jumped it so i remember running to the key to turn it off and never having to do anything else as soon as i put the wires on.

 

First thing was to replace the battery with oem Toyota battery before any of the troubleshooting!

 

yea it was but have also charged it again as I've been using it. I've also tried to add a jumper with no help.

If the voltage is low you get an error right away on the scanner so it's not battery related from my guess.

 

P3102: What’s the sub-code? It’s 524…599. This might even be the most important one?

Can't find a sub code in tis? Help if anyone knows how to find it?


C2300: What does Techstream show for voltage in U,V and W phases?

U= 12.18v
V= 12.34v
W= 12.18v

 

i just replaced the battery the 3rd time with a working Prius with the black fuse box on the positive terminal and also the ground wire since it's easy and to troubleshoot this.

 

Attaching more pics from tis where the car says no data in park but when i put it neutral it shows neutral. Something is causing it to think its not in park.

 

The car is in neutral I can push it and verify even when when I press P and TIS shows P with no data value it's still in neutral.

 

Anyone? I appreciate your time!!!

I promise to help out with issues on this forum and esp in Houston area

 

Can u help with looking for sub code on tis tech stream? I'm trying to find the sub code for p3102.
