ESP® Hydraulic Unit/Control Module Assembly Removal and Installation

CAUTIONPerforming certain prohibited service operations will affect the original performance of the ESP® hydraulic unit / control module assembly. Do not perform the following prohibited service operations: Never disassemble ESP® hydraulic unit/control module assembly, loosen blind plug or remove motor. Performing any of these prohibited services will affect original performance of ESP® hydraulic unit/control module assembly. Do not allow brake fluid to get on painted surfaces. Painted surfaces will be damaged by brake fluid, flush it with water immediately if any fluid is spilled. Regarding ESP® hydraulic unit/control module assembly removal and installation, confirm specified torque and use hand tool to avoid damage. Use care not to allow dust to enter ESP® hydraulic unit/control module. Do not place ESP® hydraulic unit/control module on its side or upside down. Handling it in inappropriate way will affect its original performance. Do not give an impact to hydraulic unit. Brake fluid is extremely damaging to painted surfaces. If brake fluid contacts a painted surface, immediately wipe it off and flush the surface thoroughly with water.

Yaw Rate/G Sensor Removal and Installation

Reference: YAW RATE/G SENSOR ON-VEHICLE INSPECTION

CAUTIONIf you do not take proper precautions when removing and installing the yaw rate / G sensor, you can damage it or cause it to lose its original performance. Avoid using an impact wrench to remove or install the yaw rate / G sensor. Using such a tool increases the risk of over-tightening the assembly's bolts and damaging the sensors. Be careful not to drop or otherwise expose the sensor assembly to a large impact. If the sensor assembly is dropped or hits hard against something, do not try to disassemble and repair it but replace the sensor assembly with a new one.
