How to diagnose an error?
IMPORTANT TO KNOW
The self-diagnosis process of Toyota vehicles can only be performed using the DLC1 and DLC2 connectors.
The test block is made in the form of a small plastic module equipped with a cover. Depending on the car model, the location of the connector may be different, but usually it is located in the engine compartment on the left side. The block cover has the inscription “Diagnostic”. In older Toyota versions, the device is located next to the battery.
For Toyota Karina 1992-1997, as well as Corona and Mark 1992, error codes can only be read by reading the blinking LEDs. In newer versions of vehicles, the DLC2 module is located in the car interior. It can be seen under the center console panel or at the driver’s feet, under the steering wheel. The module is made in the form of an oval or circle. The diagnostic process consists of closing certain contact elements of the pad, which must be connected in a specific sequence.
Algorithm of actions for verification:
- The plastic protective cover is removed from the connector. On the back of the cover there is a special diagram indicating the terminals of the block.
- Using a piece of wire, cable, or paper clip, you need to make a jumper that is mounted between pins numbered TE1 and E1.
- The key is inserted into the lock, the ignition is activated. During the diagnosis, the heating and air conditioning systems must be turned off.
- During the test, the Check Engine (for powertrain diagnostics) and O/D (for transmission) LED indicators should be observed. The number of times the light blinks and the intervals should be recorded by the user.
Pin designations on the DLC diagnostic board
You can determine whether there are any malfunctions in the operation of the internal combustion engine (ICE) and gearbox by two symptoms:
- the LED bulbs blinked evenly with a single interval and duration of 11 times;
- The Check indicator blinks long and evenly with intervals of 4.5 seconds.
If there is no contact diagram on the cover or it has been erased, you can determine the required pins as follows:
- The ignition system in the car is turned on.
- One of the contact elements of the light indicator is connected to any standard engine “ground” bolt.
- The second output of the light bulb is connected in turn to each contact of the diagnostic block.
- When the Check indicator lights up on the instrument panel, you can conclude that the desired pin has been found.
To read the code, you need to count the number of LED blinks:
- when a combination appears, the LED blinks quickly, flashes for a few tenths of a second;
- the time interval between decimal and unit readings will be no more than 1.5 s;
- the pause between each subsequent code will be 2.5 seconds;
- Series of codes for different malfunctions are separated by a pause of 4.5 seconds.
How to reset the error?
To clear the fault code, perform the following steps:
- The ignition system in the car is turned on.
- On the diagnostic board, to reset the control unit memory, the TC and E1 contacts are closed.
- Within the next three seconds, the user must press the brake pedal at least 8 times.
- Then you need to make sure that the LED indicator blinks with a pause of 0.5 seconds.
- The ignition is turned off and the jumper is disconnected from the pins. If the error codes are successfully reset, the anti-lock brake system indicator does not light up on the instrument panel.
GOOD TO KNOW
You can use a computer to clear fault codes. If the diagnosis was performed using a laptop, software is used to reset the memory.
