1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)
2. Remove the following parts:
Trunk board (See TRUNK BOARD REMOVAL/INSTALLATION.)
Trunk side pocket (See TRUNK SIDE POCKET REMOVAL/INSTALLATION.)
trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)
3. Pull back the trunk side trim (LH) to a position which allows for the removal of the rear body control module (RBCM). (See TRUNK SIDE TRIM REMOVAL/INSTALLATION.)
4. Remove the rear body control module (RBCM) from the body with the connector connected. (See REAR BODY CONTROL MODULE (RBCM) REMOVAL/INSTALLATION.)
5. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)
6. Verify that the voltages of each of the terminals are as indicated in the Terminal Voltage Table (Reference).
If the voltage is not as indicated in the table, inspect the parts under Inspection item(s).
If the system does not launch normally even though inspection items are normal, specify the location of the malfunction based on the instructions from the on-board diagnostic system and the symptom troubleshooting, and perform repairs.
