Diagnosis Procedure
- CHECK INSIDE KEY ANTENNA INPUT SIGNAL 1
- Turn Ignition Switch ON.
- Check signal between BCM harness connector and ground using oscilloscope.
(+) (-) Condition Signal
(Reference Value)BCM Connector Terminal M16 116 Ground Ignition Switch ON and any door is open When Intelligent Key is not in the antenna detection area When Intelligent Key is in the antenna detection area 128 When Intelligent Key is not in the antenna detection area When Intelligent Key is in the antenna detection area
Is the inspection result normal?
YES
Replace BCM. Refer to REMOVAL AND INSTALLATION .
NO
GO TO STEP 2 .
- CHECK INSIDE KEY ANTENNA CIRCUIT
- Turn Ignition Switch OFF.
- Disconnect BCM connector and Inside Key Antenna (Console) connector.
- Check continuity between BCM harness connector and Inside Key Antenna (Console) harness connector.
