DTC Troubleshooting: 102

EPS (LKAS) Control Unit DTC 102: Torque Sensor VS1 and VS2 Lines Clear the DTCs with the HDS. Turn the ignition switch OFF, then turn it ON (II). Watch the adaptive cruise control (ACC)/LKAS indicator. Does the adaptive cruise control (ACC)/LKAS indicator come on?
YES | - | Go to Step 4 .
NO | - | Intermittent failure, the system is OK at this time.■
Check for DTCs with HDS. Is DTC 102 indicated?
YES | - | Go to Step 5 .
NO | - | Do the appropriate troubleshooting for the cord indicated.■
Turn the ignition switch OFF. Disconnect the torque sensor 3P connector and EPS (LKAS) control unit connector D (3P). Check for continuity between EPS (LKAS) control unit connector D (3P) terminal No. 1 and No. 3. Is there continuity?
YES | - | Repair short between the PNK and WHT/GRN wires in the torque sensor circuit between EPS (LKAS) control unit and torque sensor.■
NO | - | Go to Step 8 .

On the sensor side, check for resistance between torque sensor coil 3P connector terminals No. 2 and No. 3. Is the resistance between 10−40 Ω (at 20 °C, 68 °F)?
YES | - | Check for loose terminals in the EPS (LKAS) control unit connectors, and repair if necessary. If no poor connections are found, replace the EPS (LKAS) control unit. ■
NO | - | Replace the torque sensor. ■
