Steering Switch Check

1. AV SWITCH SELF-DIAGNOSIS FUNCTION CHECK 
   1. Start AV switch self-diagnosis function. Refer to "AV SWITCH SELF-DIAGNOSIS FUNCTION  ".
   2. Operate steering switch.

   Does steering switch operate normally?

   1. YES: INSPECTION END.
   2. NO: GO TO 2.
2. CHECK HARNESS 
   1. Turn ignition switch OFF.
   2. Disconnect AV switch connector and spiral cable connector.
   3. Check continuity between spiral cable harness connector terminal and AV switch harness connector terminal.
