Read & Clear Volvo Fault Codes

Volvo vehicles are equipped with an onboard computer, also known as the Engine Control Module (ECM), that constantly monitors the various systems and components of the car. If a fault is detected, the ECM will store a diagnostic trouble code (DTC) that can be retrieved and used to diagnose the problem. Understanding how to read and clear these fault codes can be a valuable tool for Volvo owners and help them keep their cars running smoothly. This article will provide a step-by-step guide on how to read and clear Volvo fault codes, including what tools and equipment you will need and how to interpret the codes. Whether you are a professional mechanic or a do-it-yourselfer, this guide will give you the information you need to diagnose and resolve faults in your Volvo correctly.

Is your Volvo check engine light on? Learn how to troubleshoot what is causing the check engine light and how to clear them using an OBD-II Scanner. This document provides instructions on reading and clearing Volvo fault codes or Diagnostic Trouble Codes (DTC).

What you will need

Codes that trigger the check engine light can be read with a generic OBD-II scanner. Codes stored in all other modules, such as ABS, Airbag/SRS, Transmission, and Central Electronic Module (CEM), require a Volvo scanner. The YOUCANIC Full System Scanner can read all control modules of a Volvo vehicle.

Procedure

1. Locate the diagnostic port under the dashboard. 
2. Connect your scanner to the port.  Turn on the ignition. 
3. Turn on the scanner and select Diagnosis—next select Volvo. 
4. Choose Automatically Search or choose Vehicle select and scroll to pick your model such as XC70, V70, S60, S40, V40, V50, XC60, XC90, S60, S70, S80, C30.
5. From the main menu, select the control module you want to diagnose—for example, Engine Control Module, SRS – Airbag Control Unit, or Anti-lock Brake System.
6. Next, choose to Read Codes and write down all the DTCs. 
7. Write down all the codes that have a PRESENT or CURRENT status. Reach each problem to understand the problem better. 
8. Fix the problem that you found in the previous step. Then reconnect the scanner, go back to the main menu, and select Clear DTC Faults or Erase DTC, depending on the scanner. 
9. Please turn off the ignition for ten seconds and turn it back on. If the code can not be cleared, the problem that triggered the code has not been fixed yet.

You need to use a Volvo scanner that you purchase that supports your Volvo model. Otherwise, you may not get error codes even when a dashboard warning light stays on. These instructions work on all 1996 and newer Volvo models, including C70, V70, S60, S40, V40, V50, XC60, XC90, S60, S70, S80, and C30.
