Hi guys, new here but I've been lurking for a bit. Searched around for a while on this issue but couldn't seem to see anyone with what appears to be an unresponsive GMDLBP.
I am having an issue with my GMDLBP install in an 03 Silverado 1500HD. I purchased a bedlocker for my truck, its an electric rolling tonneau cover (if you google it, its the older model with the 4 button fob). I want to use the remote fob that came with it to lock/unlock the truck and arm/disarm the alarm so I only need to carry the one fob with me. The bedlocker has lock/unlock (ground pulse) wires which I have run up and into the cab.
Here's where its getting tricky for me. When I plug the GMDLBP into the harness with all the wires connected except purple (data) The unit flashes once as I plug it in and then does nothing. Push the button, nothing happens, start the truck, nothing happens. The only reaction I can get from the GMDLBP is the initial flash when I plug it in.
Things I have tried:
Short and long press' of the button
Tested my connections with a multi-meter to make sure everything is what I think it is.
Disconnected everything but constant power and ground, same results
Replaced the wiring harness and the GMDLBP separately (I thought the unit might be bad so I ordered another)
To rule out ground wire issues I tried 3 separate chassis bolts, not of them have issues according to my meter.
Shorting all the pins on the GMDLBP unit to try to get it to reset
My wiring:
Brown (-) -- Nothing
Green (-) -- Lock output from bedlocker
Blue (-) -- Unlock input from bedlocker
Violet/white -- Nothing
Violet -- Violet pin 2 from ODBII port (disconnected after nothing changed when connected it)
Pink/White (-) -- Nothing (although I recently read that I may need to connect this to get the rear doors on the crew cab to unlock?)
Pink -- Nothing
Orange (-) -- Nothing (No panic button the bedlocker remote so it is not required)
Red (+) -- Red wire from ignition harness
Black (-) -- Grounded to chassis
At this point I am thinking either I'm missing a required wire or I'm just unlucky enough to have gotten 2 bunk units (or I'm missing something super obvious, its been known to happen).
Anyway, if anyone has any thoughts or advice on this I could really use some help.
Much appreciated,
