ESP(R) Hydraulic Unit / Control Module Assembly Removal and InstallationCAUTION:
^ Never disassemble ESP(R) hydraulic unit / control module assembly, loosen blind plug or remove motor. Performing any of these prohibited services will affect original performance of ESP(R) 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(R) 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(R) hydraulic unit / control module.
^ Do not place ESP(R) 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.

5) Connect ESP(R) hydraulic unit / control module assembly connector (1) by pull up the lock lever (2).
6) Connect negative (-) cable to battery.
7) Bleed air from brake system.
8) Check each installed part for fluid leakage.
9) Connect SUZUKI scan tool to DLC.
10) Turn ignition switch to ON position. And SLIP indicator light flush. (Other than replace with new one) If other than SLIP indicator light lights, check DTC and repair it.
11) Turn ignition switch to ON position. And ESP(R) warning light, SLIP indicator light, ESP(R) OFF light, EBD warning light (brake warning light) lights and ABS warning light flush. (Replace new one)
12) Check DTC.
NOTE:
If any DTC(s) other than C1075 are detected, sensor calibration can not be completed. Repair the detected it(s) first.
13) Perform Sensor Calibration of ESM
14) Perform ESP(R) Hydraulic Unit Operation Check.
15) Turn ignition switch to OFF position once and then ON position. In this state, make sure that indicator light and warning light turns off.
16) Check DTC(s) are not stored in ESP(R) hydraulic unit / control module.
