1. Clean any debris off the mating surfaces of the HCU and ABM.

CAUTION: When installing new O-rings or solenoid valve stem seals, do not use any type of lubricant.

2. If the seals (1) on the solenoid valve stems (2) are not new, replace them all. Each of the solenoid valve stem seals must be new to keep out moisture and debris; do not reuse solenoid valve stem seals.










3. Replace the pump/motor connector O-ring (1) if it is not new. Be sure the O-ring is properly seated in the mounting groove (2).










4. Align components and install the ABM (1) on the HCU (2).










5. If equipped with ABS-only (non-ESC vehicle), install the three screws (1) attaching the ABM (2) to the HCU. Tighten the mounting screws to 2 Nm (17 in. lbs.).










6. If equipped with ESC, install the four screws (1) attaching the ABM (2) to the HCU. Tighten the mounting screws to 2 Nm (17 in. lbs.).





7. If necessary, install the mounting pins (1) in the ICU (2) and tighten to 11 Nm (97 in. lbs.).










8. If the mounting bracket (3) needs to be installed on the ICU (1), install the mounting pins in the ICU as necessary and tighten to 11 Nm (97 in. lbs.). Insert the mounting pins into the grommets mounted in the bracket, then install the single mounting bolt (2). Tighten the mounting bolt to 11 Nm (97 in. lbs.).
