Pre-Operation Checks

Check that the battery voltage is normal before operating the vehicle electrical experiment bench.

Ensure that the computer connections are secure.

Inspect the power cable for any disconnections or insulation damage.

Verify that the battery cables are properly connected.

Make sure the fault simulation switch is in the correct position.

Turn the ignition switch to the ON position and check the instrument panel and wiring for any abnormalities. If everything is normal, turn on each light switch to check that all lights are functioning properly. Press the horn button to ensure the electric horn works. Press the corresponding switches to check that all motors operate normally. Only proceed with testing or measurements if everything is functioning correctly.

Product Operating Procedures

Fault Detection Operations:

Use a multimeter to check the following components:

Check Battery Voltage:

Verify that the battery voltage is normal and that it can provide 12V to the constant power line.

Check Light Switches:

Turn on the light switch to the first position and check if the front and rear parking lights illuminate properly, as well as the instrument panel and license plate lights. Switch to the fog light position and check if the front and rear fog lights illuminate properly.

Check Headlight Dimmer Switch:

Operate the headlight dimmer switch to check if the high beams, low beams, and passing lights function correctly.

Check Turn Signal Switch, Warning Light Switch, Reverse Light Switch, Brake Light Switch, and Horn Button:

Activate the turn signal switch and check if the left and right turn signals flash correctly.

Press the warning light button to verify that the front and rear warning lights flash properly.

Press the reverse light switch to ensure the reverse lights illuminate correctly.

Press the brake light switch to check if the brake lights and high-mounted brake light illuminate properly.

Check Power Window Switches, Mirror Adjustment Switches, and Wiper Switch:

Press each power window switch to verify that the corresponding power window motors operate normally.

Rotate the mirror adjustment switch to check if the corresponding mirrors move as expected.

Set the wiper switch to the appropriate position and check if the wiper motor functions properly.

Common Faults and Solutions

Maintenance and Care

To ensure the system is safe and reliable, disconnect the power supply and remove the negative terminal of the battery after testing is complete.

Do not place the experiment bench in excessively humid conditions or in direct sunlight.

To prevent interference, avoid placing magnetic materials near the equipment.

During the operation of the experiment bench, do not randomly plug or unplug circuit connectors to avoid accidental damage.

Usage Precautions

Do not plug or unplug ECU connectors before the negative terminal of the battery is removed.

Do not plug or unplug any connectors when the ignition switch is in the "ON" position.

When using diagnostic tools, ensure correct usage methods are followed.

Do not measure the resistance of sensors or actuators through test ports while the ignition switch is in the "ON" position. If necessary, measurements must be taken under the guidance of an instructor with the ignition switch in the "OFF" position. Pay attention to proper measurement methods.

Regularly recharge the battery as needed.
