307 boot problem

[mustalahti]

Hi

I'm having trouble fixing boot of my 2005 307. So far I have changed microswitch, lock and wiring harness. Checked every fuse on the car and done BSI reset multiple times. I measured the new switch and it works as it should. Also tested continuity on all wires in the new harness. Boot light works as it should when manually opening or locking. I tested the lock with external power supply and it works with 12v.

I'm finally going to have access to diagbox/pp2000 in the near future. Never used the software, so what should I be looking for to try fix or diagnose the problem? Any other ideas on fixing or diagnosing the problem?

Things are getting even more frustrating. No errors showing in diagbox. Can't open boot via computer and pressing switch does not show on computer. Boot open/close status does show.

Fault must be in BSI. Wiring checked from boot to BSI and all are ok. Connectors also ok.

Can the BSI see the microswitch being pressed?
Have you supplied the output wire from the BSI with 12v & does it pop the tailgate?

BSI does not see microswitch being pressed. I have not tried BSI output wire with 12v, just measured continuity. I will try it 12v when I have time.
