Initial Checks:

1. Confirm the LED panel is ON – ensure the BTSI/Power light is active.

2. Check the Ramp IN/OUT fuse.

3. Does the CLOSE command light activate when pressing a button?

Diagnostic Questions:

1. Is the door switch adjusted properly?

2. Are the fuses on the main VM fuse box good?

3. Is the Ramp ON/OFF switch plugged in?

4. Check the Ramp ON/OFF relay.

5. What is the status of the Ramp on the LED panel?

6. Are the limit switches installed correctly?

Reference Notes & Locations:

1. Toyota/Honda: Located under the rear bench (passenger side on RU). Fuse box is in the rear driver corner under the plastic cover.

2. Ramp ON/OFF relay: Located at rear driver quarter panel near the C-pillar. Power is present when the door opens; ground is constant.
