   Does "LOW BATTERY VOLTAGE" appear in self-diagnosis results display? 

   1. YES >> GO TO 2.
   2. NO >> Inspection is completed.
2. STARTING INSPECTION 
   1. Disconnect VDC/TCS/ABS control unit connector E218. Then reconnect it securely.
   2. Perform self-diagnosis.

   Do any self-diagnosis items appear? 

   1. YES >> GO TO 3.
   2. NO >> Poor connection. Repair or replace applicable connector.
3. CHECKING VDC/TCS/ABS CONTROL UNIT POWER SYSTEM (1) 
   1. Disconnect VDC/TCS/ABS control unit connector E218.
   2. Turn ignition switch ON (but do not start engine).
   3. Check voltage between VDC/TCS/ABS control unit harness connector E218 and body ground.
