Monitor "Wheel Speed Sensor-Left Rear" parameters in "Current Data" with GDS.
Specification : Wheel speed proportionally increase to rotation speed of wheel
Fig.1) Rear LH wheel speed sensor data with low wheel rotation speed
Lift vehicle with suitable lift and refer to shop manual to remove wheel and wheel guard.
Substitute with known-good Rear LH wheel speed sensor.
Ignition "ON".
Position the shift lever to "N".
Rotate wheel slowly by hands.

Is the measured waveform within specifications ?
 | ▶ Refer to shop manual to replace Rear LH Wheel Speed Sensor and then go to "Verification of Vehicle Repair" procedure. |
 | ▶ Substitute with known-good HECU and check for proper operation. If problem is corrected, replace HECU and then go to "Verification of Vehicle Repair" procedure. |
In case of replacing HECU, perform following procedures.
1. "ASP Calibration" for steering angle sensor offset correction.
2. "Longitudinal G-Sensor Calibration" for longitudinal sensor offset correction.
3. "Variant Coding".
