When “ [B2520] ST ANGLE SEN CALIB” is displayed

If the steering is turned during the adjustment, perform the
adjustment again.

If any condition other than above exists, check the connection
conditions between steering angle sensor, AFS control unit,
CONSULT-II and harnesses, and then perform the adjustment
again. After the adjustment is completed, replace AFS control
unit if [B2520] is not erased from self-diagnostic results.
CAUTION:
If [U1000] CAN COMM CIRCUIT or [B2515] ST ANG SEN SIG is displayed, first refer to LT- 8 4 ,
"SELF-DIAG RESULTS" of self-diagnostic results, and then perform the diagnosis.
9. Turn ignition switch OFF, and then turn ON again.
CAUTION:
Never skip this step.
10. Drive the vehicle to the straight-ahead position, and then stop it.
11. Select “ST ANG SEN SIG” on “SELECTION FROM MENU” screen of “DATA MONITOR” of CONSULT-II.
Make sure that “ST ANG SEN SIG” is within 0 ± 2.5°. If it is other than 0 ± 2.5°, perform steps 1 to 10
again.
