Terminal and Connector Inspection

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.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found?

	▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Power Circuit Inspection" procedure.

Power Circuit Inspection

■ Power Inspection

IG "ON" & ENG "OFF"

Measure the power voltage of "Front Center Left Sensor" at IPM(Intelligent integrated Platform Module)

Specification : Approx. 12 V

Is the signal output normal?

▶ Go to "Ground Inspection" procedure.

▶ Thoroughly check fuses or connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

■ Ground Inspection

IG "ON" & ENG "OFF"

Measure voltage between power voltage of "Front Center Left Sensor" at IPM(Intelligent integrated Platform Module) and ground terminal of "Front Center Left Sensor", LID2 terminal of "Front Center Left Sensor" or LID3 terminal of "Front Center Left Sensor".

Specification : Approx. 12 V

Is the signal output normal?

▶ Go to 'Inspection of LIN communication line between Front Center Left Sensor and IPM[PAS(Parking Assist System)]

▶ Check a circuit between Front Center Left Sensor and chassis ground and poor connection.

Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

LIN communication line Inspection

■ Inspection of LIN communication line between Front Center Left Sensor and IPM[PAS(Parking Assist System)]

Connect GDS and select "Oscilloscope"

IG ON, ENG OFF and Shift lever D

Set a stuff or obstacle near the Front Center Left Sensor

Measure a waveform of LIN communication line between Front Center Left Sensor and IPM[PAS(Parking Assist System)]

Specification : Refer to "Signal Waveform"

Is measured value normal?

	▶ Fault is intermittent caused by IPM[PAS(Parking Assist System)] DTC was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Check a circuit between Front Center Left Sensor and IPM[PAS(Parking Assist System)] and poor connection. And then repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
