Terminal and Connector Inspection

Many malfunctions in the electrical system are caused by poor harness and terminals.

Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

Has a problem been found?

	▶ Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to "CAN communication circuit inspection" procedure.

CAN Circuit Inspection (EPS ↔ABS/ESP)

■ Check open/short to ground in CAN communication line

IG key "OFF".

Disconnect EPS CM connector and ABS(ESP) connector.

Measure resistance between CAN-High terminal of the EPS CM harness connector and CAN-High terminal of the ABS(ESP) ECM harness connector.

Measure resistance between CAN-Low terminal of the EPS ECM harness connector and CAN-Low terminal of the ABS(ESP) ECM harness connector.

Is the measured value within specification ?

▶ Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

▶ Check CAN communication circuit for short to battery in harness and then go to "Verification of Vehicle Repair" procedure.

▶ Check if there is an error in the ABS(ESP) system. First repair it as necessary and then go to "Verification of Vehicle Repair" procedure.

▶ Repair open or short circuit in the CAN communication line and then go to "Verification of Vehicle Repair" procedure.
