Diagnostic Procedure
- CHECK VEHICLE SPEED SIGNAL
Check the signal between Intelligent Key unit connector and ground.
SIGNAL REFERENCE VALUE CHARTTerminals Condition Signal (Reference value) (+) (-) Intelligent Key unit connector Terminal M32 35 Ground Speed meter operated [When vehicle speed is Approx. 40 km/h (25MPH)] OK or NG
OK: Check the condition of harness and connector. If it is OK, check the self-diagnosis results using CONSULT-II again.
NG: GO TO 2.
- CHECK HARNESS CONTINUITY
- Turn ignition switch OFF.
- Disconnect Intelligent Key unit and unified meter and A/C amp. Connector.
- Check continuity between Intelligent Key unit connector and unified meter and A/C amp. Connector.TERMINAL CONTINUITY CHART

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.
