Repair Importance Level: 3/3
Repair Difficulty Level: 3/3

Possible causes
Low Battery charge
Starting system
Low quality fuel
Clogged Fuel filter
Faulty Engine Control Module (ECM)

It appears it does not recognize your ignition key as valid. Make sure you have no other transponder keys near the one you are using.

Depends on model. http://www.obd-codes.com/p1605

OBD-II code P1603 indicates an issue with TCU communication.
There are communications that exist between the engine control module, or ECM, and the transaxle control module, or TCM. This communication is done through a control area network, or CAN. With the communication of the CAN, an independent pin and wiring is needed to receive a signal that includes sensor information from the ECM. The more information there is to communicate, the more wiring that is needed. When it comes to CAN communication, all of the information communicated is done alone control modules like the ECM and TCM using CAN lines. When there is a problem with these lines, the ECM will detect the problem and store a P1603 trouble code; the storing of the trouble code is what causes the SES or check engine light to illuminate on the dash.
Possible causes of trouble code P1603 include:

• Faulty transaxle control module (TCM)
• Faulty engine control module (ECM)
• Harness running from the TCM to the ECM has a short
• There is a poor electrical connection between the TCM and ECM

Diagnosing the exact cause of the problem should always begin with a visual inspection that could reveal bad wiring, loose connections, or damaged parts. From there, it is a matter of running down the list to determine what needs to be replaced. In general, a bad ECM will cause a loss of power, poor fuel economy, and stalling engine. While a bad TCM will have more prevalent transaxle issues like erratic shifting
P1605 and P1605
These codes are indicating a starting problem and rough idling. Code p1604 is a very vague code and diagnosing it without having a symptom is very complicated. And code p1605 is rough idling which means that the computer have noticed a rough idle situation usually this code is accompanied by other codes or if it's alone then I would suspect a fuel pressure issue. These two codes involve diagnosis and we'll need to dig into this problem deeper to find out what's causing them, Unless you are an experienced technician who need assistance then I will suggest that you take your vehicle to your local toyota dealership and they should be able to find the problem.

P1604 TOYOTA - Startability Malfunction https://www.autocodes.com/p1604_toyota.html

Its a computer related problem and you will need to take the car to Toyota service for further analysis.

code p1747 refers to CAN data bus, TCM /instrument panel--malfunction===causes wiring---connections--trouble code/s stored in other system/s
I don;t have the other codes but code p 1603 refers to the same CAN bus fault
call a service dealer to get the p 600 code explanation

In order for me to help u I need to know is it a po1604 or p1604 and I need to know what car or engine then I can tell you right away

For a Toyota, it indicates a startability problem, it is a very vague diagnostic troubleshoot code and therefore not component specific.

Components to check, Crank Shaft Position sensor, Spark Plugs, MAF sensor, fuel pump... etc.
