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

id1002x2005400

Caution

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

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. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)]) •  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) [(E)])
		No	Go to the next step.
2	INSPECT FOR SHORT TO POWER SUPPLY IN CAN-BUS No.1 •  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].) •  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) [(E)])
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) [(E)])
		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 terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].) •  Disconnect the EPS control module connector. •  Disconnect the auto leveling control module / adaptive LED headlights control module connector. •  Disconnect the SAS control module connector. •  Disconnect the electronically controlled brake unit / 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 (SKYACTIV-G or SKYACTIV-X) ―  Between PCM terminal 2T and body control module (BCM) terminals 3W (SKYACTIV-G or SKYACTIV-X) ―  Between PCM terminal 2AK and body control module (BCM) terminals 3X (SKYACTIV-D) ―  Between PCM terminal 2AL and body control module (BCM) terminals 3W (SKYACTIV-D) •  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. (SKYACTIV-G or SKYACTIV-X) ―  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. (SKYACTIV-G or SKYACTIV-X) ―  Repair or replace the wiring harness because there is an open circuit in the wiring harness between PCM terminal 2AK and body control module (BCM) terminal 3X. (SKYACTIV-D) ―  Repair or replace the wiring harness because there is an open circuit in the wiring harness between PCM terminal 2AL and body control module (BCM) terminal 3W. (SKYACTIV-D) ―  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 [(E)].) ―  Replace the PCM because there is a short to ground in the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.8].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))].) (See PCM INSPECTION [SKYACTIV-X 2.0].) (See PCM INSPECTION [SKYACTIV-D 1.8].) (See PCM INSPECTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))].)
