2006 Dodge Ram Cummins Remote start prob

Hey all

I have recently put a Compustar Pro 1WSH-S (remote starter) into a 06 Dodge Turbo Deisel. Now the problem with the set-up is once the Truck has sat over night it will not stay running on the remote start. When my customer remote starts the truck, it waits the 12 secs (I have it set to wait about 12 secs for the glow plugs as per customer request), it cranks and runs for approx 5 secs then shuts down. The remote starter then cycles through the start and stop phase 2 more times then gives up. Now i have talked to my distributors about this and we have come up with it either being a poor tach signal, or the voltage in the truck is dipping below the compustar threshold which shuts the unit down. (This truck is equipped with "pre-heaters" in the climate control system, which heats the air in to the cabin befor the engine warms up, they draw ALOT of power) I am alittle unsure about the voltage dropping, my reason for this is that i would think once the voltage drops and the compustar shuts down wouldn't not attempt to start again? Also for the tach i went to the ECM on the drivers side of the engine, plug closest to the rad(i can't think of the wire colour). I have tested the tach multiple times and have not noticed any serious drop. If anyone has come across the same issue or has another suggestion please let me know.

Thank you

Will the truck remote start when it been already warmed up....?

The 04 is a much different breed than the 06.

DOES IT?

This truck that you are doing is one of the hardest I had done thus far. I got the tach wire from the ECM, and I believe that the wire was blue, but I am not sure. I also remember there being about 3 ignitions, one which needed to be powered up by a negative pulse(using a relay). I believe that wire was purple and yellow. I dont think you have a tach signal problem though, because the vehicle is starting. Are getting some sort of inhibit? Which alarm is installed? Since it has been months that I have done a dodge RM, do they have some sort of transponder, or a chip in the key? What is happening to you sounds alot like when you try and RM a GM with passlock un bypassed.

Make sure  the 06 rams get power from the battery, the second start wire is getting correct resistance when it is suppose to along with the accessory feed to it with that one properly.

Tach should be a blue wire at the ecm on the side of engine. These trucks do come with transponder keys so make sure your not losing something on that end.

If the key is gray it is a transponder, if it is black it has no chip.

That is not always the case, ive seen black dodge keys with transponders in them.

How it comming with the trouble shooting

Hey all sry it took so long for me to reply, i managed to tear tendons in my right wrist so i have been going for R&R. Yes the Truck will start once it is warm, as for the glow plug timer being set to 20 secs i don't understand the reason for that since the glowplugs stay on for no more then 6-7 secs, even when it is real cold (this comming from the customer, who i trust in this situation). Now i got tach from the ECM front plug pin 24 i belive. I was thinking about Alt sensing but if its a voltage issue would it not show up there aswell? There is PATS system in this truck, I used a PATS Chrysler 04+ programmed fine. I know that this is not the issue since it starts fine once it is warm. Now i did not know that u need to hook up a 2nd start with a resistor, although the truck starts fine when its warm. As for Power yes i ran fused lines in from the battery. What i tried was re-learning tach but that has not seemed to help. I have also tried a new 1WSH-S unit with no luck. I am Stumped lol  Thanks for all the tips, i will try to find out if i need to add a resistor to the 2nd start, i can't remember if i hooked up a 2nd start, i don't think i did because the bypass does that (i believe) Thanks again

Hey Hymer,

Yeah the voltage thing is normal, i called the dealership and the Tech said that the voltage drop is due to the "Pre-heaters" in the climate control system. What they do i pre-heat the cabin air so u have heat right away, instead of waitin 20 mins for the deisel to warm up. I don't think i can mess with the tach sense on the compustar. Yeah as for the glow plugs my customer asked for 10 secs.

I just put in a Viper 160xv in my 2006 Ram and it is working fine.

I used 2 resistors, 1 for the starter 2 thru a relay and 180 ohm resistor and 1 for the accessory thru a relay and a 620 ohm resistor (calls for a 610 ohm but 620 is what was available).

Resistors run through the relays to ground and you need to cut the PURPLE / Brown wire that goes to the key switch and I used the accessory + output to trigger that relay (620 ohm) and the – starter/crank wire to trigger the other relay both from the remote starter.

Bring up the strater #2 and accessory #2 diagram from the Bulldog Security web site, I modified how to trigger the relays but it is a good loyout.

Take the bottom housing off from the steering column so you get the right wire as there are 2 PURPLE / brown wires.

I ran + for all 12 volt inputs direct from the battery with a fuse and the ground through the relays to one of the ground areas under the dash where other factory hookups are.

Tach wire is pin 24 in the front ECM connector and is DK.blue/gray, front left side of engine.

Used the 15 second delay for the pre-heaters and works great. The heaters will cycle on and off for several minutes until the intake temp is high enough.

Currently just keep my spare key in the ignition and remote lock the doors. Next I’m going to tackle the bypass deal and hook up the light output.

I have the black key and it is a transponder type.

The color of the key is only important if the keyless entry is not built into the key. If the keyless is built into the key, it has a transonder chip regaurdless.

I have had great luck using Peripherals XK-532 module for these trucks. It does transponder, locks, security, and has an output that handles the second start and accessory, eliminating the need for all but one extra relay (for parking lights.

The original problem sounds like a transponder issue. I'd check your ignition cylinder wrap, and make sure you have at lest five turns of wire around the cylinder. Any less than 5, I have found, may cause intermittent operation in cold weather.

Not always true. I just did an '06 Durango with the fact remote built into the key and no chip! Even I was amazed, but I never programmed any kind of bypass after seeing no red "dot" come up on the cluster indicationg a transponder. Starts and runs pefect every time. Strangest thing I've seen in a while. An '06 with no chip.

wire tapper- This is a Ram, not a durango. Transponders are standard equipment on all 06 and newer dodge rams.

brcidd- There are no high current wires at the ignition switch.
