REMOVAL AND INSTALLATION
Note. The TCL/ASC-ECU is integrated in the hydraulic unit.
| CAUTION | Always calibrate the steering wheel sensor and the G and yaw rate sensor if the hydraulic unit (integrated in the TCL/ASC-ECU) is replaced. (Refer to G AND YAW RATE SENSOR CALIBRATION and STEERING WHEEL SENSOR CALIBRATION ) |

<< B >> HYDRAULIC UNIT (INTEGRATED WITH TCL/ASC-ECU) REMOVAL
| WARNING | The hydraulic unit is heavy. Use care when removing it. |
| CAUTION | The hydraulic unit cannot be disassembled. Never loosen its nuts or bolts. Do not drop or shock the hydraulic unit. Do not turn the hydraulic unit upside down or lay it on its side. |
Refer to WHEEL SPEED SENSOR .

Scheme 265: REMOVAL AND INSTALLATION
| CAUTION | Do not drop or shock the G and yaw rate sensor. |
| CAUTION | Always carry out calibration if steering angle is adjusted (Refer to G AND YAW RATE SENSOR CALIBRATION ). This is necessary because the TCL/ASC-ECU should update the G and yaw rate sensor neutral point. |
Scheme 266
| WARNING | Before removing the steering wheel and air bag module assembly, refer to SERVICE PRECAUTIONS and AIR BAG MODULE(S) AND CLOCK SPRING . |
| CAUTION | When centering the clock spring, always remove the clock spring from the column switch in advance. Otherwise, the sensor may be damaged. If the clock spring is not correctly aligned, the steering wheel may not be turned or the cable inside the clock spring may be broken, causing the SRS to be inoperative. Always carry out steering wheel sensor calibration after the steering wheel sensor has been installed (Refer to STEERING WHEEL SENSOR CALIBRATION ). This is necessary because the TCL/ASC-ECU should update the steering neutral point. |
