Turn ignition switch OFF and disconnect the negative (-) battery cable.
2.
Disconnect the brake fluid level switch connector (A), and remove the reservoir cap.
Be sure to completely remove foreign substances around brake
fluid reservoir and cap before opening the reservoir cap to prevent any
contamination of brake fluid and deterioration in braking performance.
3.
Using a syringe, remove the brake fluid from the reservoir.
–
Do not spill brake fluid on the vehicle as it may damage the
paint. If brake fluid comes in contact with the paint, wash off
immediately with water.
–
To prevent dust entering the reservoir, the reservoir cap should be closed again after removing brake fluid.
4.
Remove the IBAU (Refer to the AHB system - Intergrated Brake Actuation Unit (IBAU))
5.
Disconnect the connector (A) and after removing a mounting clip, disconnect the reservoir hose(B).
6.
Disconnect the brake tube from the PSU by loosening the bolt (B).
Before removing the PSU, high pressure in an accumulator of
PSU should be reduced for safety by conducting "High pressure release
mode" of GDS connected to SOUL EV.
After filling the brake fluid in the reservoir, perform the air bleed. (Refer to the AHB system - AHB system air bleeding)
4.
Conduct calibration after removing the brake pedal assembly. (Refer to the brake pedal - calibration)
5.
Tighten the PSU bracket bolts and brake tube to the specified torque.
6.
Conduct calibration after removing or installing the PSU.
Pressure sensor Calibration
The pressure sensor mounted within the PSU calculates the
pressure according to initial zeroing. Therefore, initial zero
adjustment is required when installed for the first time. After
replacing the PSU (cannot replace sensor only), the calibration must be
performed.
Calibration procedure
1.
Connect the GDS. (CAN line or OBD connector)
2.
Turn ignition switch on.
3.
Press pressure sensor calibration button.
4.
Pressure sensor calibration procedure is performed (Calibration recorded & DTC erased).
5.
Turn ignition switch off and on after calibration procedure.
