Flooded 2014 Toyota aqua need help

[pwuser156440786377]

I can find information on the 1nz fxe but I can't find any information on the 1nz 1lm. They may be both different in some way but I cant get informatio. But I wanna know if the power management control ecu would have any thing to do with the operation of the engine? I don't wanna buy a new ecu again when the one I have right now can work.

the engine / hybrid control ECU activate engine & motor drive when the Immobilizer key match the immobiliser unit ( SMART KEY ECU ) if the 2 ECUs are different & not synchronizing vehicle will not appear READY., at key insertion.

Oh ok well that could be why it failed to program using the techstream software. I would have to get another power management control ecu that came out of an aqua with the 1nz fxe and same model the s model.

You need Techstream software and Mini VCI for Toyota. If you are computer savvy you can reprogram the keys yourself using this program. You need to buy this, it a good tool to have for Hybrid cars as it can scan the car for problems including the battery. Toyota dealership uses this software worldover.
How to do it.

To buy use this link.

In case you cannot do it yourself you need someone with this software to reprogram the keys for you.

In case the remote stops working you can still getinto the car and start it.

I have the Toyota tech stream software and a mini vci cable and I could connect to the vehicle ,but when I try to program a key it failed. It says ecu communicatiin I'd has failed

These are the errors I'm getting when I'm trying to register new key

[capsat]

you need a fresh virgin key to register with a swapped KEY ECU - ENGINE ECU.
-
the already coded key is not interrogating & synchronizing, it is simply attempting to synchronize.
the errors you posted are self explanatory. 1 & 2 being the most critical.

[pwuser156440786377]

So how do I register a new key without a already registered key ?

[pwuser156440786377]

I saw this video on YouTube the guy looks like he was explaining what he did with the flooded computer but I don't understand what they are saying.

the battery voltage needs to be above 12.6V when programming a key. Your system will not initialize without first synchronizing the VIN as its coded to the car. Its a futile effort if you dont pay attention.

the ABS and SRS is required on the CAN-BUS to work as the engine ecu relies on the SRS to provide acceleration sensor reading and the ABS provides vehicle speed reading over the bus to the drive system. Missing items will prevent startup

[pwuser156440786377]

The VIN is correct and it is only codes in the engine ecu which I did not replace. All other ecu had to be replaced except for the engine ecu. Is these a way to program CAN-BUS for the srs air bag with techstream ? And will that prevent a key from being programed.

[Xulfiqar]

Can bus is not programmable, its a communication system between modules.

Do you own an oscope?

[pwuser156440786377]

No but I can buy one if I have to

[pwuser156440786377]

What about if I buy a ecu set from one car not from different cars would it still need to be reprogram

[pwuser156440786377]

Today I was able to get the car started . I had to swap the eprom chip from the old ecus to the new ones and it worked. The cars starts with no issues . Thank you all for your help and advice.
