However, the engine will continue to run until the battery is completely discharged. Turn off additional equipment (air conditioner, fan, radio, etc.) and move to the repair site.

4. Low engine oil pressure indicator.

a) The indicator lights up when the ignition key is turned to the “ON” position and should go out after the engine starts.

b) The indicator lights up if the engine oil pressure is too low.

c) If the indicator flashes or lights up while driving, you must pull over to the side of the road and turn off the engine.

– The indicator may flash after heavy braking or when the engine is idling. There is no malfunction if the indicator goes out with a slight increase in engine speed.

– The indicator may come on when the engine oil level is too low. But this indicator is not intended to inform you about low oil level, so check the level periodically with a dipstick.

Check the oil level and make sure there are no leaks.

– If the oil level is within acceptable limits and there are no leaks, tow or remove the vehicle for repair.

– If the oil level is below the minimum permissible level and there are no leaks, add oil and start the engine. If the light flashes or stays on, turn off the engine and have the vehicle towed or towed for repairs.

Problems with the shield

Common breakdowns of instrument clusters on Toyota Corolla include:

1. Failure of devices due to breakdown of stepper motors or electronics. To restore functionality, you will need to replace damaged elements or install a new combination.
2. Burnout of lighting system elements. The owner changes incandescent lamps himself; LEDs can be replaced at a service center.
3. Turn off the backlight and some indicators. This indicates a failed fuse or broken wiring harness. On older cars (E100 or E110), the problem occurs when contact with the car body is broken.

Design features of different models of devices

The instrument panels of Corolla cars of different generations differ in the following elements:

• microprocessors that process information from controllers;
• switching connectors;
• digitization of instruments (for example, modifications for Japan have a speedometer with a maximum mark of 180 km/h);
• number and location of indicators;
• configuration and dimensions of the plastic casing;
• method of attachment to the frame.

The car owner may try to install a dashboard with additional features or a modified design. To ensure functionality, you will need to partially change the wiring harnesses or introduce additional wires.

Owners of cars manufactured in the 90s are forced to make repairs due to the natural wear and tear of components and the lack of spare parts to restore standard components.

When installing another dashboard on a Corolla E150 or E180, electronics reprogramming will be required, performed at a service center.

General recommendations

The instrument cluster of cars does not require periodic maintenance, but if the backlight LEDs fail, it is necessary to remove the assembly and re-solder the damaged elements.

Since the shield contains electronic components, interference with the structure leads to irreversible damage to the unit.

It is recommended to carry out repairs in a service center equipped with special equipment for soldering and testing the functionality of the unit.

What function does the element perform?

The instrument panel is designed to inform the driver about the operating modes and failures of various vehicle systems. There are special indicators indicating the inclusion of external lighting devices.

The display shows current and historical data stored in the memory of the on-board computer.

To read information in poor visibility conditions, LED backlighting with brightness adjustment (optional) is provided.
