1.CHECK INSIDE KEY ANTENNA INPUT SIGNAL 1

1. Turn ignition switch OFF.
2. Check signal between BCM harness connector and ground using oscilloscope.

   (+) | (–) | Condition | Signal (Reference value)
   BCM
   Connector | Terminal
   Instrument center | M122 | 78, 79 | Ground | When Intelligent Key is in the passenger compartment. |
   When Intelligent Key is not in the passenger compartment. |

Is the inspection result normal?
YES>>GO TO 4.
NO>>GO TO 2.
2.CHECK INSIDE KEY ANTENNA CIRCUIT

1. Disconnect BCM connector and inside key antenna (instrument center) connector.
2. Check continuity between BCM harness connector and inside key antenna (instrument center) harness connector.

   BCM | Inside key antenna (instrument center) | Continuity
   Connector | Terminal | Connector | Terminal
   M122 | 78 | M75 | 2 | Existed
   79 | 1

3. Check continuity between BCM harness connector and ground.

   BCM | Ground | Continuity
   Connector | Terminal
   M122 | 78 | Not existed
   79

Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair or replace harness.
3.CHECK INSIDE KEY ANTENNA INPUT SIGNAL 2

1. Replace inside key antenna (instrument center). (New antenna or other antenna)
2. Connect BCM connector and inside key antenna (instrument center) connector.
3. Check signal between BCM harness connector and ground using oscilloscope.

   (+) | (–) | Condition | Signal (Reference value)
   BCM
   Connector | Terminal
   Instrument center | M122 | 78, 79 | Ground | When Intelligent Key is in the passenger compartment. |
   When Intelligent Key is not in the passenger compartment. |

Is the inspection result normal?
YES>>Replace inside key antenna (instrument center). Refer to Removal and Installation.
NO>>Replace BCM. Refer to Removal and Installation.
4.CHECK INTERMITTENT INCIDENT
