DTC C2002: Valve Calibration not Completed
 
 
 
 
caution
  • If there is any problem in the CAN bus lines, an incorrect DTC may be set. Prior to this diagnosis, diagnose the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
  • Whenever ECU is replaced, ensure that the CAN bus lines are normal.
 
 
 
OPERATION
Perform the master cylinder pressure sensor calibration to store the calibrated value in the ASC-ECU. At the same time, the calibrated value of cut valve and inlet valve are stored.
 
 
 
DTC SET CONDITIONS
This DTC is set when the calibrated values for cut valve and inlet valve stored in ASC-ECU are not within the predetermined range.
 
 
 
PROBABLE CAUSES
  • ASC-ECU malfunction
  • Brake fluid pressure sensor calibration incomplete
 
 
 
 
DIAGNOSIS
STEP 1. Brake fluid pressure sensor calibration
Perform calibration of brake fluid pressure sensor calibration (Refer to ).
Has the calibration succeeded?
Go to Step 2.
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
 
STEP 2. DTC recheck after resetting CAN bus lines
(1) Turn the ignition switch to the "LOCK" (OFF) position.
(2) Turn the ignition switch to the "ON" position.
Is DTC C2002 set?
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
This diagnosis is complete.
