Electronic Brake Control Module: Service and Repair

Anti-Lock Brake System (ABS) Module








Removal and Installation

NOTE: On vehicles equipped with roll stability control (RSC), the ABS module and the hydraulic control unit (HCU) are calibrated to one another. Do not swap ABS modules between RSC-equipped vehicles.

NOTE: On vehicles equipped with RSC, the ABS module is available separately from the HCU and should be serviced separately. However, if the RSC-equipped vehicle requires a new HCU, then the ABS module and the HCU must be installed as an assembly. Make sure to use the most recently released service parts.

NOTE: When installing a new ABS module, it must be configured (either by download/upload or uploading the as-built data method).

1. CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

Disconnect the battery ground cable. For additional information, refer to Battery.
2. Release the air cleaner cover retaining clips and disconnect the mass air flow (MAF) sensor electrical connector.
3. Loosen the air cleaner outlet clamp and disconnect the air cleaner cover from the air cleaner outlet pipe.
