Test Description

The anti-lock brake control module (2B373) is capable of performing on-board diagnostics using Rotunda(r) NGS Tester 007-00500 or equivalent.

The anti-lock brake control module monitors system operation and can store all defined service codes in its memory. It is important to understand that there are some concerns the anti-lock brake control module cannot recognize. Therefore, if a symptom exists and no diagnostic trouble codes are stored by the anti-lock brake control module, other diagnostic steps must be followed.

The module cannot store a diagnostic trouble code if there is no power to the module. This concern can be found by following the System Precheck procedures. Inspection and Verification (Start Testing Here)
