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.
