Determination Procedure

Caution
•  When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.
•  When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.
•  Disconnect the negative battery terminal before performing any work that requires handling of connectors.

Step

Inspection

Action

1
INSPECT FOR SHORT TO GROUND IN CAN-BUS NO.1
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Inspect for continuity at the following terminals:
―  Between gateway unit (GWU) terminal 3X and body ground
―  Between gateway unit (GWU) terminal 3W and body ground
•  Is there continuity?
Yes
Short to ground in CAN-BUS No.1 has occurred.
Determine the location of a short to ground according to the diagnosis procedure for determining the location of a short to ground in CAN-BUS No.1.
No
Go to the next step.
2
INSPECT FOR SHORT TO POWER SUPPLY IN CAN-BUS No.1
•  Connect the negative battery terminal.
•  Switch the ignition ON (engine off).
•  Measure the voltage at gateway unit (GWU) terminal 3X and 3W.
•  Is the voltage between 1.5—3.5 V?
Yes
Go to the next step.
No
Short to power supply in CAN-BUS No.1 has occurred.
Determine the location of a short to power supply according to the diagnosis procedure for determining the location of a short to power supply in CAN-BUS No.1.
3
INSPECT FOR SHORT BETWEEN CIRCUITS IN CAN-BUS No.1
•  Measure the voltage at gateway unit (GWU) terminal 3X and 3W
•  Is the voltage at gateway unit (GWU) terminal 3X and 3W the same?
Yes
Short between circuits in CAN-BUS No.1 has occurred.
Determine the location of a short between circuits according to the diagnosis procedure for determining the location of a short between circuits in CAN-BUS No.1.
No
Go to the next step.
4
INSPECT FOR OPEN CIRCUIT IN THE WIRING HARNESS BETWEEN PCM AND INSTRUMENT CLUSTER
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Disconnect the forward sensing camera (FSC) connector.
•  Disconnect the EPS control module connector.
•  Disconnect the SAS control module connector.
•  Disconnect the start stop unit connector.
•  Disconnect the active driving display connector.
•  Disconnect the 4WD control module connector.
•  Disconnect the rear power seat control module (RH) connector.
•  Disconnect the rear one-touch walk-in control module connector.
•  Disconnect the power liftgate (PLG) control module connector.
•  Disconnect the position memory control module connector.
•  Disconnect the electric parking brake control module connector.
•  Disconnect the rear power seat control module (LH) connector.
•  Disconnect the DC-DC converter (i-ELOOP) connector.
•  Disconnect the auto leveling control module / adaptive LED headlights control module connector.
•  Disconnect the TCM connector.
•  Disconnect the radar unit connector.
•  Disconnect the DSC HU/CM connector.
•  Inspect for continuity at the following terminals:
―  Between PCM terminal 2AK and gateway unit (GWU) terminal 3X
―  Between PCM terminal 2AL and gateway unit (GWU) terminal 3W
•  Is there continuity?
Yes
Because the circuit between the PCM and gateway unit (GWU) is currently normal, go back to the [TROUBLESHOOTING PROCEDURE].
No
•  Any of the following malfunctions may have occurred.
―  Repair or replace the wiring harness because there is an open circuit in the wiring harness between PCM terminal 2AK and gateway unit (GWU) terminal 3X.
―  Repair or replace the wiring harness because there is an open circuit in the wiring harness between PCM terminal 2AL and gateway unit (GWU) terminal 3W.
―  Replace the gateway unit (GWU) because there is a short to the power supply in the gateway unit (GWU).
―  Replace the PCM because there is a short to ground in the PCM.
