07 acura rdx, ak-psb05, viper 5902

Here are the details...

All self installed and have had 0 issues until my latest AdvancedKeys AK-PSB05 install.

Everything is connected D2D in an 07 Acura RDX

Expresskit DBALL bypass module

Viper 5902 Alarm

Directed SmartStart

Everything has been and still is functioning perfectly, no glitches at all, here is the problem and I can't figure it out.

I can start and stop using the AdvancedKeys AK-PSB05 module hundreds of times and no issues

I can start the vehicle via Remote Start and Smart Start hundreds of times and no issues

Here is the problem....

The very first time I use Remote Start or SmartStart and stop the remote start sequence or even enter the car and do a remote start takeover the bypass no loner works ONLY bwhen using the AK-PSB05. Keep in mind the Remote Start and Smart Start still function fine, it's only the AK-PSB05 that does not activate the bypass module. There are no light on the bypass module, almost ike it looses power.

Here is the kicker, once I unplug the D2D cable, essentially removing the power and reconnect the cable everything works as it should again untill the next time I use Remote Start or SmartStart, the AK-PSB05 has a ground-when-running wire connected to the bypass module. I tink it has something to do with everything being D2D except for the AS-PSB05 and that ground-when-running wire.

Please help or tell me if there is a way to connect a relay which is triggered from the Viper 5902 that will maybe disconnect the ground or power via the negative pulse. I can link it to Remote Shutdown to the AUX 3, that way everytime the remote start is shutdown it will remove and connect the power or ground on the bypass which will allow it to function normally again. I can do this via a toggle switch but I would like like it performed automatically by the Viper 5902.

If the moudle in question is getting it power from the D2D. You can try hardwiring it to power and ground. And see it that makes a difference. Kinda sounds like the software is crashing due to lack of power. There is a limnit on how much power the D2D can provide. And yes you can use the AUX 3 with a relay to cut either power or ground to the module on remote start shutdown. Basic setup 87a 30 for wire 85 86 for control.

Generally D2D will prevent the analog wire from working. It's strange that it's letting you use the GWR wire at all. My thoughts were to use the rearm wire of the Viper unit to pulse a relay that would cut power momentarily to the bypass unit. That may cause an issue when locking the vehicle though unless you use a timer relay like a DEI 528T. Otherwise you may have to connect the Viper in W2W to the DBALL and connect both GWA wires (from Viper and AK) to the DBALL. Make sure to diode isolate each wire.

Also the Status or 2nd Status wire on the viper 5902 could be substituted for the GWR of the dball if it is a data/wired conflict with the dball. The AK says the GWR is optional is there a reason you have it hooked up, like to overide the keysense. Any GWR should work to do the keysense overide.

The status wire (GWR) can be used but again if D2D is kept connected, it will ignore the analog status wire when the Viper sends the DBALL the command to bypass the immoblizer. Therefore back to square one. That wouldn't help the issue with the Advanced Keys system. I need to correct my statement above though. I meant to say - Otherwise you may have to connect the Viper in W2W to the DBALL and connect both status GWR wires (from Viper and AK) to the DBALL. Make sure to diode isolate each status GWR wire.

According to the Ak manual The GWR is only to enable the keysense override when remote started. Shouldn't have any effect on the dball and it won't matter if the dball ignores the GWR since it wouldn't be hooked to the dball. He only needs the keysense bypass(override) if he did the steering lock bypass with the key blank. Otherwise he didn't even need to hook it up.

Correct. I've also read the manual thoroughly as I normally would before I respond to posts. And I also speak from experience in the field. The AK has two wires that can be used for keysense, a (+) trigger and a (-) trigger wire. The (-) one is the GWR wire which is the wire used for a bypass module. Just like any other remote starter, you need a bypass module on this vehicle to allow the AK to start the vehicle. The Viper and other brands also can use the GWR to trigger the keysense to disarm the factory alarm before remote starting. That assumes you don't have an immobilizer. But this vehicle does have an immobilizer. Hence the reason for the DB-ALL. He wouldn't have any issues with this setup if it only needed the GWR for keysense on either the Viper, AdvancedKeys or any other remote start system!

The fact that you can't use the data and the GWR wire with out issues must have something to do with the design of the dball or firmware. I personally have not used the dball have used xk01, canmax400/DEI and have done D2D and wire together with out issue. Sounds like he will either need to do relay on remote start shutdown to power cycle the dball since that is when the problem is occuring. Or go W2W with the dball as it seems that alot of people have issues with the dball in data mode.

I went W2W on the DBALL to correct the issue

Good Deal. W2W is always more reliable. Glad it's working now.
