Monitor GDS Data

Connect GDS to Data Link Connector (DLC).
Diagnose EPB with GDS for DTC and state information.
In case of historic DTC: Erase DTC with GDS and verify that DTC is erased and MIL is off.
In case of active DTC: Perform ESC "Variant Coding" in the "Vehicle S/W Management " with GDS.
Delete historic C1702 and verify that code is erased and MIL is off.

* After vehicle variant coding, perform G-sensor calibration and ASP calibration.

NOTE: If C1702 code is active after variant coding, perform the procedure below.

Make sure variant coding was carried out with correct vehicle information.
Substitute with a known-good HECU and check for proper operation. If problem is corrected, replace HECU and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

* In case of replacing HECU, perform following procedures.

"ASP Calibration" for steering angle sensor offset correction.
"Longitudinal G-Sensor Calibration" for Longitudinal sensor offset correction. (refer to C1285 )
"Variant Coding".
