Hello,
I installed a DEI 1400XPL in my girlfriends prius last winter and for some reason it has only worked when the temperature is above 40 degrees. Any idea what the problem could be? It will start and work fine if it is over 40. Thanks in advance for any answers.

What happens when you try to start it in colder weather?
Did you connect the tach wire? What are you using for the bypass?

The remote starter is a DEI python 1400XPL and the bypass is a idatalink ADS-TB-TL. I only hooked up one ignition and I see that in the other tech sheet that has been listed that there are 2 ignitions. Could that possibly be the problem? I wired the ignition to the brake switch which is what the bypass told me to do.
When it is cold sometimes the lights will come on and sometimes they won't. Sometimes it doesn't do anything.

Looking at the guide for the bypass module shows that you would not connect the ignition and accessory wires direct from the remote starter. There is one connection for accessory and ignition from the remote starer but it has to have diodes in place since it's only being used as an input not an output.
The bypass module takes care of ignition and starting the car. Confirm no connections are loose especially on the keyport which controls the immobilizer signal.
The tach wire is not needed in this setup. The remote starter should be set with engine checking off.
I would also reprogram the bypass unit to the car.

And the brake switch on the Prius is a constant, not ignition.

There is an ignition on the brake switch also but it is used strictly for programming the RS and bypass. It has no function other than that....

Didn't realise that Mike, I'm cutting that to immobilise both older and newer Prius for a taxi fleet, tied into trackers.

So I can't use the ignition at the brake to run the remote starter? I did it a year ago but I'm pretty sure I didn't make any connections from the remote start straight to the car as far as the ignition wires go.

Since the ADS module is engaging the start process instead of the remote starter itself, feeding the ignition wire from the 1400 may be preventing it from starting.
The DEI system has a shutdown diagnostic you can check to see why it's not starting. It may shed some light on the problem.
I do wonder something though, if this is a hybrid would you hear the gas engine turn on? I know some hybrids will start up but run off the electric system for heat and everything else and you will never hear the engine start. You only know it's on by looking at the cluster inside.

To clarify though, you will have the ignition and accessory wire connected to the car from the 1400 BUT it's thru diodes to allow the ignition power from the car being on to travel back to the remote start unit but not flow the other way from the 1400 to the car. Same goes with the accessory wire.
Also, as Mike M2 stated, it's also used that way for programming options on the 1400.
There is also a certain order of events that has to happen to allow the remote start process to work. The bypass module will trigger the brake wire prior to starting the vehicle. If there is no diode on the ignition wire from the 1400 and it's going direct to the car's ignition wire, it will prevent the engine from starting.
I suggesting checking all the connections to ensure they are setup the way the manual states. Also, check all fuses installed with the remote start setup.
