How to diagnose an engine?
Toyota Corolla self-diagnosis will allow you to figure out the source of problems in your car. Let's figure out where to start, what the error codes are and how to carry out diagnostics without special instruments and tools right in the garage.
First thing
All Toyota models older than 1988 are equipped with a multi-pin connector for diagnostics, which is located under the hood near the battery or on the left side of the car (along the way). The connectors are called DLC-1 and DLC-2. Option with index 1 is a plastic box, which is often marked “Diagnostic”. In this case, error codes are displayed directly through the “check” icon, located in a visible place for the driver. If you have a restyled or modern model of Toyota Corolla, then the light bulb is in the form of an engine, but it is the same thing. The previous information concerned owners of gasoline cars, since for diesel versions, instead of a separate light bulb, a glow plug is used: a picture in the form of a spiral.
After carrying out diagnostics on your own, errors in the event of an automatic transmission malfunction are displayed through the “AT Check”, “Power” or “OD” lamps. Failures in other systems, for example, TRS or SRS and ABS, are displayed on the corresponding lamps.

16 Toyota Corolla 2001-2003 Malfunctions of the “amplifier module” circuit code P1300 P1305 P1310 P1315 P1300 P1305 P1310 P1315 Malfunctions of the “amplifier module” circuit (no 1)A direct ignition system (dis) is used. The direct ignition system increases the accuracy of determining the ignition timing, reduces the loss of electrical charge, and generally improves the reliability of the ignition system by eliminating the ignition distributor link
Dis is a single-cylinder ignition system in which one cylinder is ignited from one ignition coil. In a single-cylinder ignition system, the spark plug is mated to the end of the secondary winding. The high-voltage discharge generated in the secondary winding goes directly to the spark plug. The spark from the spark plug goes from the center electrode to the ground electrode.
The electronic engine control module (ecm) sets ignition timing and provides the ignition signal (igt) for any cylinder. Based on the Igt signal, the power transistors cut off the current going to the primary winding in the ignition coil. At the same time, the igniter sends an ignition confirmation signal (igf) to the electronic engine control module (ECM) as an additional safeguard against failure.
DTC No
| Diagnosis Condition DTC | Possible failure point | |
| P1300 P1305 P1310 P1315 | When the engine is running, the engine electronic control module (ECM) does not receive an ignition confirmation signal (IGF). | · Ignition system · Open or short circuit in the ignition signal circuit (IGT) from the ignition coil with “amplifier module” · Ignition coils with “amplifier module” · ECM |
If there is news of a malfunction with code Dtc P1300, check the ignition coil No.. and the “amplifier module” electrical circuit. If there is news of a malfunction with code Dtc P1305, check the ignition coil No.. and the “amplifier module” circuit. If there is news of a malfunction with DTC P1310, check the ignition coil No.. and the “amplifier module” circuit. If there is news of a malfunction with DTC P1315, check the ignition coil No.. and the “amplifier module” circuit. Check the indicator display using a hand-held diagnostic tool. The indicator panel stores information about engine operation when a malfunction is detected, therefore, when searching for breakdowns, it is advisable to know whether the vehicle was moving or stopped, whether the power unit was heated or not, whether the fuel-air mixture was lean or enriched, etc. , at the time of the malfunction.

Toyota diagnostics with a paper clip
I know how you can connect a Japanese car with an OBD-2 connector, but the data transfer protocol differs from the standard ISO protocols with the Torque program! For those who are not in the know: Torque allows you to turn your Android smartphone on an iPhone into a fully functional on-board computer without the need to contact super-professional electricians, as would have to be done, for example, in the case of purchasing any multitronic.
And it’s convenient to mount it - you put your mobile phone in a smartphone holder on the dashboard, and you get data from such a fun gadget that costs no more than rubles.
It displays hundreds of machine parameters in real time, creates graphs, and you can carry out easy diagnostics with it at any convenient time. Most of the parameters that are taken at the service station will also be available to you. You won’t be able to carry out serious diagnostics, but I think few people need to get into the very guts of the car, when it’s enough to look at the average fuel consumption, speed, tachometer speed, coolant temperature, engine temperature, etc. of parameters in real time.
Plus system errors, for which many go to service stations. I’ll warn you right away - there are two types of Japanese cars: That is, they were brought to our country from Europe, but they are considered Japs. The conversation with them is short - this small gadget and Torque for rubles will be enough for most cars that generally have this very OBDII protocol.
In purely Japanese models, everything is more complicated. And then the normal connection to Torque does not work. Our craftsmen from the pccar forum went the hard way and made a wonderful miracle software called ECU. At the moment there are two current models of this program that allow you to delve as deeply as possible into the depths of the car’s brains, but I personally have not tested it, since I have the necessary parameters in Torque - pictures on the right.
Let me remind you that this is only a small part of the parameters that it can display. ECU2 allows you to work with ELM laces, which, for example, allows you to save the interior from the need to use wires and get by with a laptop with Bluetooth. There is no mobile version of the application. ECU3 allows you to quickly receive diagnostic information from the car, but the disadvantage will be the need to use a special K-line cord, that is, add a wire here - obviously the car will have to stand still during diagnostics.
There are certainly advantages there, but the main drawback for me is the lack of a mobile version, because the last thing I want is to carry a laptop with me in the cabin, as well as buy expensive cords. And I installed Torque for rubles from the market. For a long time I tormented Yandex, Google, searching the pccar forum. But I never found anything.
But you can’t spend a whole day searching and not find anything, this is not my way. And I went directly to the manufacturer of this powerful software - I wrote to them on the forum - guys, you know about the problem of the Japs. Please make your software work. The answer to me was calm silence. By chance, I immediately came across a discussion of this crap on the market itself where the support sent a person with a link to their website.
I found an interesting Egg there:
