Removal
1. | Turn ignition switch OFF.
2. | Disconnect the brake tubes from the HECU by unlocking the nuts counterclockwise with a spanner.
Tightening torque: A: 12.7 ~ 16.7 N.m (1.3 ~ 1.7 kgf.m, 9.4 ~ 12.3 lb-ft) B: 18.6 ~ 22.6 N.m (1.9 ~ 2.3 kgf.m, 13.7 ~ 16.6 lb-ft)
3. | Pull up the lock of the HECU connector (A), and then disconnect the connector.
4. | Loosen the HECU bracket nuts (A), then remove HECU and bracket.
Tightening torque: 16.7 ~ 25.5 N.m (1.7 ~ 2.6 kgf.m, 12.3 ~ 18.8 lb-ft)
• | Never attempt to disassemble the HECU.
• | The HECU must be transported and stored in.
• | Never shock to the HECU.
5. | Remove the 3 bolts, and then remove the bracket from HECU.
Tightening torque: 11 ~ 14 N.m (1.1 ~ 1.4 kgf.m, 8.1 ~ 10.3 lb-ft)
Installation
1. | Installation is the reverse of removal.
2. | Tighten the HECU mounting bolts and nuts to the specified torque.
3. | After installation, bleed the brake system. (Refer to ABS bleeding)
In a case of replacing ESC HECU, operate following functions.
1. | "Steering Angle Sensor Calibration" for steering angle sensor offset correction. (Refer to the "Steering system")
2. | "Longituginal Sensor Calibration" for Longituginal sensor offset correction. (Refer to the "Yaw-rate and Gsensor")
