2. CHECKING SELF-DIAGNOSIS RESULTS (2) 
   1. Disconnect pressure sensor VDC actuator connector E21 and VDC/TCS/ABS control unit connectors E218. Then reconnect them securely.
   2. Perform VDC/TCS/ABS control unit self-diagnosis again.

   OK or NG 

   1. OK >> Poor connection of connectors. Repair or replace suspect connector. Perform self-diagnosis again.
   2. NG >> GO TO 3.
3. CHECKING PRESSURE SENSOR CIRCUIT 
   1. Disconnect VDC actuator connector E21 pressure sensor and VDC/TCS/ABS control unit connector E218.
   2. Check continuity between VDC/TCS/ABS control unit harness connector E218 and VDC actuator pressure sensor harness connector E21.

   OK or NG 

   1. OK >> GO TO 4.
   2. NG >> Open or short in harness. Repair or replace the suspect harness.
4. CHECKING PRESSURE SENSOR 

   Check pressure sensor value on "DATA MONITOR".
