On most professional-grade scan tools, ABS software is still offered as an extra-cost, add-on module or upgrade. However, recently Innova has added the ability to read ABS codes to its 3150 CanOBD2 scan tool. Consequently, scan tool manufacturers have historically limited the capabilities of their DIY and low-cost, entry-level tools to powertrain only. If you are doing mostly engine diagnostic work, then all you need is a scan tool that can do powertrain diagnostics. If the capabilities of the software are limited, or the software is out-of-date, the scan tool may not be able to access any ABS codes or run any ABS self-tests.ĪBS codes and self-tests require additional software that goes beyond what is needed to read and interact with OBD II system data. For ABS diagnostics, that means software that can read and access the ABS system.
Factory scan tools and most professional-grade scan tools, by comparison, do have bidirectional communications capabilities and can run many self-tests that are provided by the vehicle manufacturer - but only if the scan tool has the right software. This means the scan tool can only read and display codes and other PIDs (performance information data), but it can’t activate anything, run anything or initiate any self-diagnostic tests. What’s more, most DIY scan tools and entry-level scan tools do not have bidirectional communications capabilities. They are primarily designed to read and clear OBD II engine and transmission codes, not ABS codes or other body-related codes. Most do-it-yourself and entry-level grade aftermarket scan tools that can read powertrain codes lack the ability to access ABS codes (but there are exceptions). But on most late-model vehicles, a scan tool is required to read ABS, traction control and stability control fault codes. Jumping or grounding the specified pins on the diagnostic connector is usually all that’s required to flash out the codes.

A few of the older vehicle applications have manual flash codes that do not require a scan tool, such as older Chevy, Ford and Dodge pickup trucks with Kelsey-Hayes rear wheel ABS.

On most applications, the code and warning light will also temporarily disable the ABS system (and traction control and/or stability control systems if the vehicle also has these features).įinding out why the ABS light is on requires plugging a scan tool into the diagnostic connector to read out the code(s). If a fault is detected, it will usually set a code and turn on the ABS warning light to alert the driver. Leaky high-pressure accumulators are another common problem.Īll ABS systems run self-diagnostic tests when the vehicle is driven to check for faults. Internal corrosion is a leading cause of trouble in ABS hydraulic modulators, while electrical faults in wheel speed sensor circuits and pump motors can prevent the system from functioning properly.
Antilock brake systems have been around since the 1980s, so many ABS-equipped vehicles have accumulated enough miles to start experiencing ABS problems.
