Disconnect all related modules and PCM connectors and inspect for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Reconnect the connectors.

Connect the GDS and go to ""Current Data"".

Monitor modules and PCM sensor values in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).

Any change in the values indicates a poor connection. Was a connector problem found?

	▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Signal Circuit Inspection" procedure.

IG "OFF"

Measure the resistance between CAN-HIGH and CAN-LOW terminals of data link connector (Measurement "A")

Disconnect PCM connector.

Measure the resistance between CAN-HIGH and CAN-LOW terminals of data link connector (Measurement "B")

Is the measured resistance within specification ?

	▶ Go to "Check short to ground in CAN BUS" as follows.
	▶ Below 10Ω for both conditions(disconnected, connected) : Repair short between CAN BUS lines and go to "Verification of Vehicle Repair". ▶ 120Ω for both conditions(disconnected, connected) : Go to "Check CAN BUS continuity". ▶ Infinite Ω for both conditions(disconnected, connected) :Repair open in CAN communication circuit between DLC terminal and In-pannel junction box.

IG "OFF". Disconnect PCM, Instrument Cluster and ABS/ESP ECU connector.

Check resistance between CAN-HIGH terminal of Data Link Connector and chassis ground. (CAN HIGH line)

Check resistance between CAN-LOW terminal of Data Link Connector and chassis ground. (CAN LOW line)

Is the measured resistance within specification ?

	▶ Go to "Check short to battery in CAN BUS".
	▶ Repair short to ground in circuit and go to "Verification of Vehicle Repair".

IG "OFF". Disconnect PCM, Instrument Cluster and ABS/ESP ECU connector.

IG "ON"

Measure the voltage between CAN-HIGH terminal of Data Link Connector and chassis ground. (CAN HIGH line)

Measure the voltage between CAN-LOW terminal of Data Link Connector and chassis ground. (CAN LOW line)

Is the measured voltage within specification ?

	▶ Go to"Check CAN BUS continuity" as follows.
	▶ Repair short to battery and go to "Verification of Vehicle Repair".

IG "OFF". Disconnect PCM, Instrument Cluster and ABS/ESP ECU connector.

Check resistance between CAN-HIGH terminal of Data Link Connector and CAN-HIGH terminal of each module.(Measurement "A")

Check resistance between CAN-LOW terminal of Data Link Connector and CAN-LOW terminal of each module.(Measurement "B")

Is the measured resistance within specification ?

	▶ Go to "Component Inspection".
	▶ Repair open in CAN BUS line. Go to "Verification of Vehicle Repair".
