Lexus LS430 ABS Control Module Replacement Cost

ABS control module replacement is less common than most other repairs. If the brake system is properly maintained, the ABS control module can be expected to last the lifetime of the vehicle in most cases.

Anti-lock braking systems are complex, and are typically diagnosed through professional computer scanning equipment, or manufacturer specific software. The technician will communicate with the ABS control module via computer, and view real-time data to determine what fault has been detected, and how the system is behaving. Finally, if the module is suspected of failure, the module inputs and outputs must be tested physically to ensure the ABS control module is at fault before confirming the diagnosis.

Once the battery is disconnected, the technician must remove all electrical connections from the module, and all brake lines from the distribution block, which is attached to the ABS control module. Once the new control module is installed, the brake system is flushed and bled, and manufacturer specific software updates will be made.

During this repair, the entire braking system should be inspected, and the brake fluid will be completely flushed and replaced to prevent contamination of the new ABS control module.

The ABS module should not be assumed faulty, and must be tested to prevent costly misdiagnosis. They are typically very expensive, and, normally, the part is only available for purchase from the manufacturer. Replacement cost will vary for different makes and models because of parts pricing differences, and accessibility issues for the servicing technician.

Replacing the ABS control module requires advanced knowledge, and manufacturer software in order to update the new control module. This is not a DIY friendly repair.
