Lift vehicle with suitable lift and refer to shop manual to remove wheel and wheel guard.
Substitute with known-good Rear RH wheel speed sensor.
Ignition "ON".
Position the shift lever to "N".
Rotate wheel slowly by hands.
Monitor "Wheel Speed Sensor-Right Rear" parameters in "Current Data" with GDS.
Specification : Wheel speed proportionally increase to rotation speed of wheel
Fig.1) Rear RH wheel speed sensor data with low wheel rotation speed
Is the measured waveform within specifications ?
![]() | ▶ Refer to shop manual to replace Rear RH 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".
