Hello all,

if you dont have time to help me on all my issues, please help me with the remote start issue first, it is #2

I have the following vehicle, Year : 2003, Make : Acura, Model : CL Type S.

I'll make this short and sweet, after confirming with my local dealer that the clifford matrix 70.5 that i was purchasing was the new and improved model, (the original model was recalled for remote issues), I bought and went ahead and decided to install.

I have so far had a successfull installation, however I do have some questions.

1.  The remote start relay satelite has many wires, so i have a few questions:

a. do i need the accessory output, the orange wire to be connected to my accessory (yellow) wire at the ignition harness?

b. If i do not connect the accessory output, will the climate control run while in remote start mode?

c. Do i need to connect both RED inputs? 

d. The  RED / white wire, do i need to give it a 12+ constant or is it a 12 volt output.

2.  I have remote start problems.  I have made and double checked all connections. when i enable the remote start, the alarm responds and i can hear it trying to start the vehicle, i can hear relays clicking, i get a positive pulse on the purple wire for a few seconds like the install manual says to check.  It seems like it wants to start, but the starter never engages.

3. I have the 556H immobilizer bypass module.  I have connected most of it, however the pin1 green reference wire says to go to the first pin on the 7 pin connector.  I have no 7 pin connector, the actual key cylinder unit has two harnesses going to it, one has 4 wires, the other has 5. 

a. There is a blue / white wire on both harness going into the key cylinder, since i have to use a blue wire for data and there is no blue wire, it is somewhat confusing, at this point i am using the lower harnesses blue/white wire.

b. The 556h unit programs itself accordingly, although i dont think i have a reference wire enabled.  But i did program it to mode 2 and it does fast flash when i start the car using the key.

c. The 556h also blinks correctly when i use the remote start feature, i have the blue white wire going to the blue status wire on the remote start satelite for the status connection. Seems to work.

Bottom line, the remote start doesnt work, the alarm attempts to start the vehicle, it almost seems like the key is being inserted into the ignition and is being turned to the momentary start position and the accessories are cutoff momentarily for the starter to run like normal, but no starter!

thanks again.

1)
a. Yes, it is a required connection.
b. You need the accessory wire hooked up for the climate control to operate when the vehicle is remote started.
c. You need both hooked up
d. The RED / White needs to be hooked up to +12V Constant supply, it is an input.

2) Is the purple wire hooked up to the key side of the cut starter wire or the vehicle side of the cut starter wire?

3) Figure out the remote start issues prior to troubleshooting the bypass module. This way you know everything else is working fine and it is not the factory immobilizer causing your problems. To do this, temporarily restore the wire you cut for the transponder bypass and disconnect the bypass main harness. Leave a key in the ignition cylinder in the off position and remote start the vehicle to verify the remote start installation is complete. Then move on to troubleshooting the bypass. The diagram for your vehicle does not show a 7 pin harness but it does however show the reference wire in the last pin of the plug.

Acura CL uses the 5pin plug from the harness. in a green plug, thisis the factory immobilizer ring pinout

Pin 1 - Yellow/Black (Ignition)
Pin 2 - Red (Data)                                            ON 555h, it is data 1
Pin 3 - Blue (Data Synchro)                            ON 555h, it is data 2
Pin 4 - BROWN / Black (Ground)
Pin 5 - N/C  

Note, on data 2, there should be two data 2 wires. One receive and one sends. Receive is towards Ignition/immobilizer plug and send is towards ECM (towards/down facotry immobilzer wires.)

hope that helped.

10 - 4.  I read you loud and clear.  Question, why does the relay satelite need so many 12 volt inputs?

The purple wire is hooked into the WHITE/ black starter wire leading back into the vehicle, the green is going into the starter wire leading towards the key(side).  I have checked this many times, i have even thought about inverting them to see what happens, but i doubt this is such a good idea.  I thought that maybe i read the verbage wrong and i mistakenly inverted the connection, but i doubt this.

Well, heres the thing, i tried remote starting the vehicle before doing anything with the 556h.  It acted the same exact way.  I see the dash light up, i hear the relays clicking, the dash temporarily goes dark, before the starter relay lets off and i see the dash light up again, except i never hear the starter turn during the time when the dash goes dark, which is normal behavior because thats what happens when i start the car with the key. 

I tried putting the key in and leaving it in the off position, in the run position, with the doors closed, with the doors open, i checked all the blocks, (hood pin, wait to start is not connected so the alarm is not seeing a ground there) im not sure what else to do.  I tried all of these things with and without the transponder connected to the vehicle.

I installed the transponder because the instructions (the matrix alarm instructions) under the troubleshooting section say that perhaps if the remote start engages but the starter does not turn that the vehicle has an immobilizer.  Well, at that point i went ahead and went into the door and hooked up the disarm no unlock to the appropriate lead into the matrix.

The wiring guide from directechs say that the immobilizer automatically disables on unlock and enables on lock, and i can confirm this.  Something is killing the starter relay when there is no key in the ignition.  I dont know if the 556H is the correct transponder for this vehicle at this point.

Yep, thanks for the reply, i got these hooked in and at least i know i am in the correct harness, however, the 556h needs  a green reference wire supposedly needing to be connected to pin1 , and the diagram shows it going directly into the key harness on pin1? So maybe i have the wrong transponder here..

Actually, their is a data wire that is cut, i forgot right now if its data 1 or data 2, but the 556h does correctly follow the programming sequences when i program it, the led lights up just as described, and i can start the car with the key perfectly, which will make the led on the unit flash rapidly which in the manual it says that this is what it does when it is activated not by the remote start wire.

maybe i should look at the 555h instead of the 556 to see what differences they have.  What do you know of this reference wire?

I have about 6 or 7  wires hooked up right now,

black = ground, red = 12+ constant, blue = remote start notification, 1 tapping into the ignition wire, 1 tapping into a data 2 and the data 1 i believe is cut so i have a yellow going one way and the yellow/black going back the other way.

thanks again.

Mods you can close this thread.

Guys, the mistake was that i inadvertently cut the white black wire in the ignition harness and connected that to the purple and green wires from the remote relay satelite.  The white black wire is the third accessory wire.

The correct starter wire is the black white wire.  There is a reason this happened, I am color blind and get certain colors confused.

FYI the car will now attempt to run the starter, but unless i hook up the 556H transponder module, the car will not start.

It seems like the wiring is correct now for the starter and also for the transponder module as all is working as it should.

Thank you all for your assistance, the vehicle is now working.

If anyone needs help installing this system in an 2003 acura CL type S, just shoot me a line i will be glad to share my experience with you all as well.

Ron.
