Removal 1. Turn the ignition switch OFF and disconnect the battery negative (-) cable. 2. Lift the vehicle. 3. Remove the fuel pump control module mounting bolts (A).
Removal 1. Disconnect the negative (-) battery terminal. 2. Remove the rear bumper. (Refer to Body - "Rear Bumper") 3. Remove the BSD unit (A) after loosening the mounting screws. Take care not to separate the bracket from rear bumper when removing the BSD sensor.
Inspection Self diagnosis 1. Self-diagnosis process 2. How to read self-diagnostic code. After the display panel flickers three times every 0.5 second, the corresponding fault code flickers on the setup temperature display panel every 0.
