Removal
1.
Turn the ignition switch OFF.
2.
Disconnect the brake tubes from the HECU by unlocking the nuts counterclockwise with a spanner.
Tightening torque :
12.7 ~ 16.7N.m(1.3 ~ 1.7kgf.m, 9.4 ~ 12.3lb-ft)
16.7 ~ 22.6N.m(1.7 ~ 2.3kgf.m, 12.3 ~ 16.6lb-ft)
3.
Pull up the lock of the ESC control unit connector , then disconnect the connector.

4.
Loosen the ESC HECU bracket bolts (A) and nut (B), then remove HECU and bracket.
Tightening torque :
16.7 ~ 25.5N.m(1.7 ~ 2.6kgf.m, 12.3 ~ 18.8lb-ft)

   
1)
Never attempt to disassemble the HECU.
2)
The HECU must be transported and stored in.
3)

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 HECU, operate following functions
1)
"Steering Angle Sensor Calibration" for steering angle sensor offset correction (refer to C1261)
2)
"Longituginal Sensor Calibration" for Longituginal sensor offset correction (refer to C1285)
Variant coding process is necessary when :
–
HECU is replaced.
–
