Customer Question
Just did an engine swap...
Just did an engine swap on a 2012 Toyota Prius V. Car will go into aux mode but won't actually start with the new gas engine. Is there something extra I need to do? Maybe erase codes and if so how? Old engine had a rod crash out the cylinder wall. Made sure all connectors were hooked up, OBD giving misfire codes but gas engine not turning on so nothing could be misfiring...

hey how are you ,I will try to assist ypu on this issue here ,

if the battery died will you doing the swap it could have triggered the anti theft system ,lets try reseting first and we go from ther

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .the reason we do that is to take any residual power in the wiring harness to try to reset the modules ,and there will be no spark created touching them since we took battery power source out of the loop by taking both cables off

2- Hold cables Together for 60 secs ,then let go

3- Wait 30 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

You are very welcome :)

Hey, so the battery ended up just being dead. After charging it it was able to run. I got a good 200 miles on it before it now stopped and will stop almost every time I put it into drive or reverse with the attached error sign. Replaced the battery, still happening

You need to have the HV module scaned for fault we need a bigger scaner than obII one and I msire there is fault in there .
Read this recall was it performed on your car
You went 200 miles with no issues but now it is showing up quicker that means the part failing failed completely
