In order to diagnose the problem, you will need to read the ABS codes without a scanner. In this article, we will show you how to read ABS codes without a scanner.
How to read ABS codes without a scanner?
Without a scanner, one can simply read ABS code in a short time but it requires some basic knowledge about a digital multimeter and test light. However, if you do not know that much about these two devices. Simply, explore youtube to learn this.
To read ABS codes without a scanner, you will need a few things:
- A digital multimeter: A digital multimeter is a device that can measure electrical current, voltage, and resistance. You can use a digital multimeter to read ABS codes without a scanner.
- A test light: A test light is a handheld device that emits a small light when it comes in contact with an electrical current. You can use a test light to read ABS codes without a scanner.
- The vehicle’s service manual: This will have specific instructions on how to read the codes for your particular vehicle.
- Patience: This process can take some time, so be prepared to spend at least an hour on it.
In case, you do not have these materials or, don’t manage to know how to use these then you may look for an expert.

Instructions on How to Read ABS Codes Without a Scanner
With proper knowledge and necessary materials, it is very easy to read ABS code without a scanner. For making this process easier we have divided the process into 5 easy steps. Let’s see:
Step 1: Locate the ABS Control Module
The first step is to locate the ABS control module. This is usually located near the fuse box in the engine compartment. Consult your service manual for the exact location.
Step 2: Connect the Digital Multimeter to the ABS Control Module
Once you have located the control module, you’ll need to connect the digital multimeter to it. There are usually two wires that you will need to connect the multimeter to. One is usually labeled “ground” and the other is usually labeled with a “+” sign.
Step 3: Turn the Key to the “On” Position
With the digital multimeter still connected to the ABS control module, turn the key to the “on” position. This will power up the control module and allow you to read the codes.
Step 4: Check for Codes
At this point, you should check the digital multimeter for codes. The codes will be displayed as either “Current” or “History.” Current codes are codes that are currently being displayed by the control module. History codes are codes that have been displayed in the past but are no longer being displayed.
If you see any codes, write them down and then consult your service manual for more information on what they mean.
Step 5: Clear the Codes
Once you have diagnosed the problem, you will need to clear the codes from the control module. To do this, simply disconnect the digital multimeter from the control module and then turn the key to the “off” position.
By following these steps you can easily read your ABS code without a scanner. But in case, you are having trouble with ABS code and do not have expertise in using a multimeter then you should take advice from a mechanic before doing anything with code.

FAQ:
Is it good to use an ABS code reader to read the codes without a scanner?
It is not recommended to use an ABS code reader to read the codes without a scanner if you do not have good knowledge about multimeter/ABS code readers. However, if you are good at using a multimeter you can do this easily. it saves time and makes the process easier.
How do I know if the ABS system is working properly?
The ABS system is working properly if the system’s voltage reading is higher than 12 volts.
Can I read the codes without a scanner if my car’s system voltage is lower than 12 volts?
Yes, you can read the codes without a scanner if the system voltage is lower than 12 volts. However, you will need to use an ABS code reader.
Where is the ABS system’s diagnostic connector located?
The ABS system’s diagnostic connector is usually located under the dash, near the fuse box.
What is the difference between a digital multimeter and a test light?
A digital multimeter is a device that can measure electrical current, voltage, and resistance. A test light is a handheld device that emits a small light when it comes in contact with an electrical current.
Final Verdict
Reading ABS codes without a scanner is not as difficult as it may seem. With a little patience and the right tools, you can easily do it yourself. Just be sure to consult your service manual for specific instructions on your vehicle.
