Important Safety Information

Before using the device, it is important to carefully read the owner’s manual and safety instructions. Compu-Car provides this manual translated from English into Arabic to facilitate the user experience, and we do not bear any legal responsibility in the event of any errors or damages resulting from the user.

Safety Precautions

• Always perform car inspections in a safe environment.
• Wear safety gear and eye protection that meets safety standards.
• Keep clothing, hair, hands, tools, test equipment, etc., away from all moving or hot engine parts.
• Operate the vehicle in a well-ventilated work area: Exhaust gases are poisonous.
• Place blocks in front of the driving wheels and never leave the vehicle unattended while performing tests.
• Be extremely careful when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components create hazardous voltage when the engine is running.
• Put the transmission in the PARK position if the transmission is automatic, or the Neutral position if the transmission is manual, and make sure to apply the parking brake to prevent the vehicle from moving completely during the inspection.
• Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
• Do not connect or disconnect any test equipment while the ignition is on, or the engine is running.
• Keep the scan tool dry and clean of oil, water, or grease. Use a mild detergent on a clean cloth to clean the exterior of the test tool when necessary.

Remember:

Safety first! Always follow the instructions and precautions provided in the user manual. If you have any questions or concerns, don’t hesitate to contact Compu-Car’s technical support team.

Activating Components in the Vehicle Using the KM10 Car Circuit Tester

Among its many features, the KM10 allows you to activate components within the vehicle:

• In DC Voltage Mode:
  • Connect the probe tip to the positive terminal of the component.
  • The green indicator light should illuminate, indicating continuity to ground.
  • While observing the green indicator light, quickly press and release the power switch forward.
  • If the green light goes out and the red light appears, you can proceed with further activation.
  • In some cases, the indicator lights may go out or the circuit breaker in the device may trip. This could be due to overloading the tool.
  • This can happen for the following reasons:
    • The contact point you are looking for is a direct ground.
    • The component you are testing is short-circuited.
    • The component is a very high current component (i.e., starter motor).
  • In the event of a circuit breaker trip, reset it by waiting for it to cool down (15 seconds).

Warning:

• Randomly applying voltage to certain circuits may damage the car’s electronic components. Therefore, it is strongly recommended to use the car manufacturer’s diagrams and diagnostics during testing.

Note:

• When powering components, you can increase the life of the power switch if you first press the switch, then connect the tip to the component.
• The resulting bending will be at the pointed tip instead of the switch contacts, which extends the life of the device.

Testing Trailer Lights and Connections and Activating Ground Components Using the KM10 Automotive power scanner

Testing Trailer Lights and Connections:

• In DC Voltage Mode:
  • Connect the auxiliary ground lead of the device to the trailer’s ground line.
  • Check the contact points in the socket, then apply voltage to the probe tip.
  • This allows you to check the function and status of the trailer light connection lines.
  • If the circuit breaker trips, this line is likely to be grounded.
  • Reset the circuit breaker by letting it cool for 15 seconds.

Activating Ground Components in the Vehicle:

• In DC Voltage Mode:
  • Connect the probe tip to the negative terminal of the component.
  • The red light should illuminate.
  • While observing the red indicator light, quickly press and release the power switch backward.
  • If the red light goes out and the green indicator light appears, you can proceed with further activation.
  • If the green indicator light goes out at that moment or if the circuit breaker trips, this means that the car circuit tester has stopped working.
  • This can happen for the following reasons:
    • The contact point you are looking for is a direct positive voltage.
    • The component you are testing has a short circuit.
    • The component is a very high current component (i.e., starter motor).
  • In the event of a circuit breaker trip, reset it by waiting for it to cool down (15 seconds).

Warning:

• Using this function, if you are connecting to a protected circuit, the fuse may blow or the circuit may trip if you apply ground voltage to it.

Explanation of the Red/Green Polarity Indicator in the KM10 Car Circuit Tester

• Illuminates when the probe tip voltage matches the battery voltage within ±0.4 volts.
• Provides valuable additional information to the automotive technician.
• If the circuit you are testing is not within 0.4 volts (plus or minus) of the supply voltage, you will see the voltage reading on the device screen, but you will not hear a tone or see a red or green light.
• This indicates a voltage drop of more than 0.8 volts or an increase of 0.8 volts or more on the battery voltage.
• To determine the battery voltage, remove the tip from the circuit and press the power switch forward.
• The battery voltage will be displayed on the device screen.
• The difference between the battery voltage and what is read on the circuit is either a voltage drops or a voltage increase.
• This allows you to determine the voltage drop without having to go back and check the battery.

Tracking and Locating Open Circuits Using the KM10 Automotive circuit tester

In most cases, an open circuit will be indicated by a blown fuse, a burnt or cut wire in the circuit, or a tripped electrical protection device for the circuit (circuit breaker as an example or any other type of protection the circuit is equipped with).

Here’s how to track and locate open circuits:

1. Remove the fuse from the fuse box.
2. Use the probe tip to activate each of the fuse contacts and the side where the device breaker trips are the circuit with the short.
3. Note the identification symbol or color of this wire and write it down.
4. Follow the wire as far as you can along the wiring harness.

Example:

• If you are tracking a short in a brake light circuit, locate the desired wire from among the wires using the color of the wire extending from the bulb.
• Penetrate the insulation using the probe tip and press the power switch forward to activate and energize the wire.
• If the circuit breaker trips, this means that you have checked the wire that has the problem.
• Cut the wire and activate each side using the electronic circuit tester.
• The side where the breaker trips is the side with the problem.
• Follow the wire in the direction where the breaker in the device trips and repeat this process until you reach the problem point to solve it.
