Inspection Procedure

HINT:

When U0123/62, U0124/95 and/or U0126/63 is output together with C1210/36 and/or C1336/39, inspect and repair the trouble areas indicated by U0123/62, U0124/95 and/or U0126/63 first (See DTC U0073/94 CONTROL MODULE COMMUNICATION BUS OFF; DTC U0100/65 LOST COMMUNICATION WITH ECM / PCM; DTC U0123/62 LOST COMMUNICATION WITH YAW RATE SENSOR MODULE; DTC U0124/95 LOST COMMUNICATION WITH LATERAL ACCELERATION SENSOR MODULE; DTC U0126/63 LOST COMMUNICATION WITH STEERING ANGLE SENSOR MODULE  ).

1. PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR 
   1. Perform zero point calibration of the yaw rate and acceleration sensor (See CALIBRATION  ).
2. RECONFIRM DTC 
   1. Turn the ignition switch off.
   2. Clear the DTCs (See DTC CHECK / CLEAR  ).
   3. Drive the vehicle at a speed of 30 km/h (19 mph) or more, turn the steering wheel, and decelerate (depress the brake pedal) the vehicle.
   4. Check if the same DTC is recorded (See DTC CHECK / CLEAR  ).

      Result 

      DTC OUTPUT RESULT
      
      

      Result	Proceed to
      DTCs (C1210/36 and/or C1336/39) are output	A
      DTCs (C1210/36 and C1336/39) are not output	B

      HINT:

      • The DTCs are recorded because zero point calibration has not been completed.
      • End the procedure because the same DTCs were not recorded after completion of zero point calibration.

        B: END 

        A: Go to next step 

3. CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION 
   1. Turn the ignition switch off.
   2. Check that the yaw rate and acceleration sensor has been installed properly (See INSTALLATION  ).

      OK: 

      The sensor is tightened to the specified torque. The sensor is not installed in a tilted position  .

      NG: INSTALL YAW RATE AND ACCELERATION SENSOR CORRECTLY  (See INSTALLATION  )

      OK: REPLACE BRAKE ACTUATOR ASSEMBLY  (See REMOVAL  )
