Standard Ignition ABS Wheel Speed Sensor P/N:ALS397

Keep your anti-lock braking system reading wheel speed accurately with the Standard Ignition ABS Wheel Speed Sensor ALS397. It installs as a direct-fit replacement in the front right position for the 2003-2005 Mercedes-Benz ML350 and 2003-2005 Mercedes-Benz ML500.

This sensor monitors the rotational speed of its wheel and reports that signal to the ABS control module, which uses the data to manage anti-lock braking and, where equipped, traction and stability control.

• Front right fitment: cataloged for the front right wheel position on the listed applications.
• Wheel-speed monitoring: generates the speed signal the ABS module relies on to modulate braking.
• Direct-fit replacement: designed to install for the listed Mercedes-Benz applications.

Signs the sensor may need replacing include an illuminated ABS warning light, a stored wheel-speed fault code, or ABS/traction control that drops out. These symptoms can have other causes, so diagnose the fault before replacing. If a failed front right wheel speed sensor is the cause, this ALS397 replaces it.

Manufacturer part number ALS397.
