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/HCU assembly, it must be configured (either by download/upload or uploading the as-built data method). For additional information, refer to Programmable Module Installation (PMI) in MODULE CONFIGURATION
article.
