REAR BODY CONTROL MODULE (RBCM) INSPECTION
id094000002200
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)
2. Remove the following parts:
3. Pull back the trunk side upper trim (LH) to a position which allows for the removal of the rear body control module (RBCM). (WGN only) (See TRUNK SIDE UPPER TRIM REMOVAL/INSTALLATION.)
4. 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.)
5. Remove the rear body control module (RBCM) from the body with the connector connected. (See REAR BODY CONTROL MODULE (RBCM) REMOVAL/INSTALLATION.)
6. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)
7. Verify that the voltages of each of the terminals are as indicated in the Terminal Voltage Table (Reference).
