ERROR IS DISPLAYED ON VEHICLE IDENTIFICATION [VEHICLE INFORMATION ACQUISITION] SCREEN [(US)]

SM2566476

id1002x1005400

Caution
• Perform the following malfunction diagnosis only when vehicle identification [VEHICLE INFORMATION ACQUISITION] is not passed according to the [TROUBLESHOOTING PROCEDURE]. (See TROUBLESHOOTING PROCEDURE [(US)].)

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 cable 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 cable. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)])
• Inspect for continuity at the following terminals:
― Between body control module (BCM) terminal 3X and body ground
― Between body control module (BCM) 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.
(See DETERMINING SHORT TO GROUND LOCATION (CAN-BUS No.1) [(US)])
No
Go to the next step.
2
INSPECT FOR SHORT TO POWER SUPPLY IN CAN-BUS No.1
• Connect the negative battery cable. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)
• Switch the ignition ON (engine off).
• Measure the voltage at body control module (BCM) 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.
(See DETERMINING SHORT TO POWER SUPPLY LOCATION (CAN-BUS No.1) [(US)])
3
INSPECT FOR SHORT BETWEEN CIRCUITS IN CAN-BUS No.1
• Measure the voltage at body control module (BCM) terminals 3X and 3W.
• Is the voltage at body control module (BCM) terminals 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.
(See DETERMINING SHORT BETWEEN CIRCUITS LOCATION (CAN-BUS No.1) [(US)])
No
Go to the next step.
4
INSPECT FOR OPEN CIRCUIT IN THE WIRING HARNESS BETWEEN PCM AND BODY CONTROL MODULE (BCM)
• Switch the ignition off.
• Disconnect the negative battery cable. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)
• Disconnect the EPS control module connector.
• Disconnect the AFS control module / auto leveling control module connector.
• Disconnect the SAS control module connector.
• Disconnect the electric parking brake control module / DSC HU/CM connector.
• Disconnect the TCM connector.
• Inspect for continuity at the following terminals:
― Between PCM terminal 2S and body control module (BCM) terminals 3X
― Between PCM terminal 2T and body control module (BCM) terminals 3W
• Is there continuity?
Yes
Because the circuit between the PCM and body control module (BCM) 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 2S and body control module (BCM) terminal 3X.
― Repair or replace the wiring harness because there is an open circuit in the wiring harness between PCM terminal 2T and body control module (BCM) terminal 3W.
― Replace the body control module (BCM) because there is a short to the power supply in the body control module (BCM). (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)
― Replace the PCM because there is a short to ground in the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
