CALIBRATION
Note. Use this procedure to center the steering wheel if: The steering actuator has been replaced, The steering control ECU has been replaced, The steering column or gear has been disconnected, or The steering wheel is still off-center after completing the steering angle sensor initialization.

- VGRS SYSTEM CALIBRATION PROCEDURE (USING SST CHECK WIRE) FACE TIRES STRAIGHT AHEAD NOTE: Drive the vehicle to confirm that the steering wheel is centered. NEXT: Go to next step CHECK DTCs Check for DTCs. Refer to «DTC CHECK / CLEAR»(ref-382810-S16608627522011012800000) . Result Result Proceed to DTC C1591/51 is not output. A DTC C1591/51 is output. B B --> Go to step 4 A: Go to next step PERFORM ACTUATOR ANGLE INITIALIZATION NOTE: Complete steps d to h within 1 minute. Turn the engine switch on (IG). Start the engine. Center the steering wheel. Using SST check wire, connect terminals TS and CG, and TC and CG of the DLC3. SST: 09843-18040 Disconnect the SST check wire from terminal TS of the DLC3, and turn the steering wheel to the left 180° or more. Connect the SST check wire to terminal TS of the DLC3. Disconnect the SST check wire from terminal TC of the DLC3, and turn the steering wheel to the right 180° or more. Connect the SST check wire to terminal TC of the DLC3. HINT: When the master warning light (VGRS) comes on, DTC C1591/51 is memorized. Disconnect the SST check wire from the DLC3. Turn the engine switch off. NEXT --> Go to step 1 FACE TIRES STRAIGHT AHEAD Confirm that the steering wheel is centered when facing the tires straight ahead. NOTE: Drive the vehicle to confirm that is steering wheel is centered. Result Result Proceed to Steering wheel is off-center. A Steering wheel is centered. B B --> Go to step 8 A: Go to next step UNLOCK STEERING ACTUATOR NOTE: Do not start the engine. Turn the engine switch off. Disconnect the negative (-) terminal cable from the battery. Disconnect the K26 connector from the steering actuator. Connect a jumper wire from terminal LV+ to the positive (+) battery terminal and another jumper wire from terminal LG+ to the negative (-) battery terminal. NOTE: Do not apply voltage for more than 3 minutes. NEXT: Go to next step STEERING CENTER ADJUSTMENT Center the steering wheel. NOTE: If the spiral cable of the airbags and VGRS system is not centered when the steering wheel is installed, release the system lock and center the spiral cable. Refer to «INSTALLATION»(ref-382579-S40410976732011012800000) . Slowly turn the steering wheel to the left. Turn it to the right approximately 2 turns from the point where resistance begins to be felt (the end of the spiral cable) while steering. This will center the spiral cable. (If excessive force is applied to the end of the spiral cable, the cable may break.) NEXT: Go to next step LOCK STEERING ACTUATOR Disconnect the positive (+) and negative (-) battery terminal cables from the steering actuator. Connect the K26 connector to the steering actuator. Connect the negative (-) terminal cable to the battery. Turn the steering wheel approximately 3° to the left and right. Confirm that the reaction force can be felt. NOTE: If the above procedures are not followed correctly, a DTC will be detected. If a DTC is detected, perform the above procedures again and then check for DTCs. Perform these procedures with the engine switch off. NEXT --> Go to step 1 ADJUST ACTUATOR ANGLE HINT: Activating and ending test mode will complete actuator angle adjustment. Make sure the engine switch is off. NOTE: Do not touch the steering wheel during these procedures. Using SST check wire, connect terminals TS and CG of the DLC3. SST: 09843-18040 Turn the engine switch on (IG). Confirm that the "VGRS TEST MODE" is displayed on the multi-information display when test mode is activated. Turn the engine switch off. Disconnect the SST check wire from terminals TS and CG of the DLC3. Turn the engine switch on (IG) again. NEXT: Go to next step CHECK MASTER WARNING LIGHT Confirm that the master warning light (VGRS) off. Turn the engine switch off. Confirm that master warning light (VGRS) operating normally. NEXT: Go to next step CHECK STEERING WHEEL OPERATION Start the engine. Perform the steering angle sensor initialization. Refer to «INITIALIZATION»(ref-382810-S14733650782011012800000) . Turn the steering wheel from lock to lock to check that it rotates approximately 2.7 turns. Drive vehicle to confirm steering wheel is centered. NEXT --> END
- VGRS SYSTEM CALIBRATION PROCEDURE (USING TECHSTREAM) FACE TIRES STRAIGHT AHEAD NOTE: Drive the vehicle to confirm that the steering wheel is centered. NEXT: Go to next step PERFORM VGRS SYSTEM CALIBRATION Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Chassis / VGRS / Utility / Steering Angle Adjust. Perform the procedures displayed on the Techstream. NEXT: Go to next step CHECK MASTER WARNING LIGHT Confirm that the master warning light (VGRS) is off. Turn the engine switch off. Disconnect the Techstream from the DLC3. Confirm that master warning light (VGRS) operating normally. NEXT: Go to next step CHECK STEERING WHEEL OPERATION Start the engine. Perform the steering angle sensor initialization. Refer to «INITIALIZATION»(ref-382810-S14733650782011012800000) . Turn the steering wheel from lock to lock to check that it rotates approximately 2.7 turns. Drive vehicle to confirm steering wheel is centered. NEXT --> END
