    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    Unfortunately the v6 firmware files didn't fix these issues. I copied over the 2 .zbo files to an empty micro SD card, inserted into the black control box, and waited 1 minute. After removing the SD card I verified the following issues were still present: - Unable to adjust the trunk speed...

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    Stephen @Hansshow just got back to me this evening and had the Support Team send me Hansshow Firmware v6. Going to try flashing the Control Box tomorrow and see if this fixes the close and trunk speed issues.

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    @JT_M3P are you able to adjust the Trunk Closing Speed? When I hold down the Tailgate button, I can't seem to get it past 3 consecutive beeps. I've seen other videos of the older Hansshow silver metallic control box go up to 6 beeps for the fastest trunk speed setting.

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    Similar to the original post topic, I ran into a scenario where the Trunk fails to close when attempting to press the Close button on the Tesla Screen. Has anyone else run into this issue? Scenario: Open Trunk via new Tailgate button and Close using the Tesla Screen. The Closed button is...

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    It's really hard to tell in the Hansshow install video and instructions, but routing the strut wires through the blue grommets goes through the crack between and taillight and trunk body, thus not causing the trunk weather stripping to bulge. You do however have to lift the weather stripping a...

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    I also didn't need to remove the bumper or tail lights for the strut wires. I had originally routed the strut wires through the tail light holes as @magrider mentioned, but ended up re-doing this and routed through the 2 blue grommets in the lower trunk area as shown in the Hansshow v4 install...

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    Good call on that hidden plug that wasn't in the instructions! That fixed the open/close issue for me too and the trunk now works. In case others face the same problem due to the latest 6th edition instructions not showing any plugs connected to slot #8 on the new control box, I added an orange...

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    12/4 Update. Still no luck getting the trunk to open or close. Verified the Trunk wires were matched correctly (directly wired fish male + female wires). Still haven't had any luck getting ahold of an Hansshow engineer via WhatsApp and not sure how much longer I'll be able to hold out without...

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    I've reached out to Hansshow via WhatsApp earlier this week but unfortunately support has not yet been able to put me in contact with an engineer to help me troubleshoot. For now I manually closed the trunk so I can still drive the car, and if need can manually open the trunk by low crawling...

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    Thanks for the suggestion. Just gave that a try and unfortunately doesn't look like it changed the behavior after I plugged the power back in.

    Hansshow Model 3 Power Trunk v4 Not Opening or Closing

    Is anyone having issues with their Hansshow Power Trunk v4 not opening or closing? Here's a quick video of me attempting to initialize the control box in which you'll hear 2 beeps, then the unit seems to shutdown after 5 seconds and doesn't respond to any commands (tail lift button, tesla app...
