I'm trying to use the EVO-ALL with a cellular modem to remotely unlock the vehicle. The EVO-ALL has been flashed with the latest firmware and was successfully programmed to the vehicle for CAN bus only (blue LED flash pattern displayed).
Everything unlocks properly if the EVO-ALL purple/white wire (unlock) is briefly grounded within 20 or so minutes of the vehicle ignition turning off.
If the vehicle is locked with the OEM keyfob (lock button pressed twice) and 20 minutes elapses with the ignition off, the EVO-ALL stops unlocking the vehicle. Grounding the purple/white wire causes the EVO-ALL's blue LED to briefly flash, but nothing happens on the vehicle.
Based on the two diodes coming off the EVO-ALL white/red wire (ignition/accessory), I'm thinking this wire should be providing voltage momentarily prior to unlock, but no voltage ever appears on it. If this wire is used only for remote start, then this wire isn't relevent in our scenario.
Any ideas?
