So you do have HIDs? Might be the cause. The flash to pass module seems to get confused if it doesn't experience a normal amp draw on the stock headlight wiring circuit. Guess I should clarify what I was talking about and why it might apply to you.
Couple years ago I tried the 9007 upgrade mod, replacing the stock 9004s. At the same time I replaced my headlight switch because it was old - the draw of even the stock lights was making the switch overheat and fail, which caused my lights to cut out at the worst times.
The 9007 bulbs draw more current than stock 9004s, so I figured I would wire it up myself. I used the stock headlight wiring and connectors to only control a pair of relays, one for high beams and one for low beams. The relays channeled power directly from the battery to new high temp headlight connectors. The only load that the stock headlight switch and wiring experienced was that of switching the relays on. The relays handled all the current of the actual bulbs. I would imagine that many HID setups work exactly the same way!
For a few weeks it worked fine for me. Then I began to notice odd behavior. The high beams would stay on sometimes, and I would sometimes see the high beam indicator dimly lit on the dash. I don't remember what other symptoms were. I do excellent wiring so I know it wasn't my fault, and the relays tested good.
I double checked everything against wiring diagrams, and what I gathered from this was the above conclusion; that the flash to pass module did not like my setup. Returning to stock fixed everything immediately.
If your HID setup uses the stock headlight wiring to activate it, you probably are having the same problem. I don't know for sure a solution for that. Perhaps putting a couple resistors on the stock headlight circuits would make the FTP module happy because it would "see" the current draw of stock lights.
Just a thought. I could be totally wrong, or I could be onto something here
