GATEWAY UNIT (GWU) INSPECTION [TYPE-B]

id0940000064z4

1. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2. Remove the following parts:

(1) Passenger-side front scuff plate (See FRONT SCUFF PLATE REMOVAL/INSTALLATION.)

(2) Passenger-side front side trim (See FRONT SIDE TRIM REMOVAL/INSTALLATION.)

(3) Lower decoration panel (See DECORATION PANEL REMOVAL/INSTALLATION.)

(4) Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

(5) Dashboard under cover (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION.)

(6) Passenger-side lower panel (See LOWER PANEL REMOVAL/INSTALLATION.)

(7) The nuts (See GATEWAY UNIT (GWU) REMOVAL/INSTALLATION [TYPE-B].)

3. Remove the gateway unit (GWU) from the body with the connector connected. (See GATEWAY UNIT (GWU) REMOVAL/INSTALLATION [TYPE-B].)

4. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

5. 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.
