OK: Check the condition of harness and connector. If it is OK, check the self-diagnosis results using CONSULT-III again.

NG: GO TO  2.

1. Turn ignition switch OFF.
2. Disconnect Intelligent Key unit and unified meter and A/C amp. Connector.
3. Check continuity between Intelligent Key unit connector and unified meter and A/C amp. Connector.

OK or NG 

OK:

• If the measured value is not waveform but 0V constant, the harness or connector between the using receiving the vehicle speed signal from unified meter and A/C amp. may be malfunctioning. Check these wirings.
• If the measured value is not waveform but 5V or 12V constant, replace unified meter and A/C amp.

NG: Repair or replace harness.
