Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?






Signal Circuit Inspection

Open or Short Check
1. ENG "ON".
2. Turn the steering wheel to the left or right.
3. Measure waveform between signal terminal of the HECU harness connector and chassis ground with osciloscope.

Specification :Check the voltage range (HIGH : 2.9±0.1V ~ 4.4±0.1V LOW : 1.2±0.1V ~
2.1±0.1V) of the sensor signal in case of turning left, turning right, center position.
If normal waveforms such as fig1, 2, 3 are detected in each condition, It is normal.




4. Is the measured waveform within specifications?
