OUTSIDE KEY ANTENNA OPERATION INSPECTION
1. Disconnect each outside key antenna connector.
2. Check the following.
  - Check continuity between door mirror (outside key antenna) connector D2 (driver side), D32 (passenger side) terminals 6 and 7
  - Check continuity between outside key antenna D116 (back door) terminals
    Driver side, Passenger side
    
    6-7: Continuity should exist.
    
    Back door
    
    1-2: Continuity should exist.
OK or NG
1. OK: GO TO 3.
2. NG: Replace outside key antenna.

OUTSIDE KEY ANTENNA CIRCUIT INSPECTION

Disconnect Intelligent Key unit connector.

Check continuity between each outside key antenna connector D2 (driver side), D32 (passenger side), D116 (back door) terminals 1,2,6,7 and Intelligent Key unit connector M34 terminals 17,18, 19, 20, 37, and 38.

OUTSIDE KEY ANTENNA CONNECTOR CONTINUITY SPECIFICATIONS

Back door	1 (L/B) -17 (OR/L): Continuity should exist.
	2 (W/B) -18 (PU/R): Continuity should exist.
Driver side	7 (BR/W) -19 (SB): Continuity should exist.
	6 (R/Y) - 20 (R/G): Continuity should exist.
Passenger side	7 (G/Y) - 37 (G): Continuity should exist.
	6 (L/Y) - 38 (PU/W): Continuity should exist.

Check continuity between each out side key antenna connector terminals 1, 2, 6, 7 and ground.
