DIAGNOSIS TSB Revision ACTIVE STABILITY CONTROL SYSTEM (ASC) 35C-193 STEP 6. Master cylinder pressure sensor calibration Q: Has the calibration succeeded? YES : Go to Step 7. .) Then go to Step 8. STEP 7. Check whether the DTC is reset. YES : Replace the hydraulic unit (incorporates in .) Then go to Step 8. NO : Intermittent malfunction. (Refer to GROUP 00 − How to Cope with Intermittent Malfunction .) STEP 8. Check whether the DTC is reset. YES : Return to Step 1. DTC C1219: Abnormality in steering wheel sensor signal CAUTION • If there is any problem in the CAN bus lines, an incor- rect diagnostic trouble code may be set. Prior to this • Whenever the ECU is replaced, ensure that the CAN bus lines are normal. • When the steering wheel sensor is replaced, always perform calibration to make ASC-ECU learn the neutral .) • Do not drop the G and yaw rate sensor or subject it to a shock. • When the G and yaw rate sensor is replaced, always perform the calibration to make ASC-ECU learn the .) • When the hydraulic unit (integrated with ASC-ECU) is replaced, after turning the ignition switch ON and OFF , and .) . CIRCUIT OPERATION Steering wheel sensor outputs the signal to ASC-ECU via CAN . |
