09 corolla with smart key , cm4200 start

Hi,

I just purchased 2009 Corolla LE with Smart Key system and after market CM4200-VD command start unit. This is manufactured by Compustart, however I did not get any remotes for the command start or user manual with this unit.

I'm trying to figure out what remote I would need and how to program it to Smart Key system. I contacted compustart  and this is what they told me "m< color=#1f497d>ost commonly, what you would have to do, is get into the vehicle.  DO NOT STEP ON FOOT BRAKE.  And Press the engine start button til the ignition turns on (sometimes you have to click it twice, once for Accessory second for Ignition) and keep pressing it on and off for 5 times the last time leaving it on to program.  If this is too difficult to do, you should consider bringing it back to your original place of installation."

< color=#1f497d>I tried out this step to see if I can get in to programming mode, but it does not do anything. I read that the tail lights are suppose to flash when the unit is in the programming mode, but my system does not do anything. I'm not very familar with samrt key system, and that is what's making it very difficult.

< color=#1f497d>Can someone please direct me to right path? This car came from difference province, so I don't have much information on how/where the command start was installed.

< color=#1f497d>Thank you.

First of all you reallly have to get rid of that macro:             < >< color=#1f497d>

Second of all do you have a bypass unit on this vehicle? What brand and model number? It may need to be progammed. You pobably will not be able to program a new remote with that style of starting system. Try manually crossing wires to the ignition on the remote start unit

Thank yo for the reply.

1st, I don't know how to disable macro. Not sure how it was enabled to start with.

2nd. It's a Compustart unit. The brain is CM4200. Also sold by NuStart...in Canada. What will crossing the wires on the starter will do?

Dude you gotta have a bypass for this to work.

First thing you need to do is order a remote from your nearest  dealer...

If the remote start system was actually working, look at the top inside of the windwhield for an antenna.  On it is a model number.  It will help you figure out what type of Compustar remotes to get.  When you get the proper type of remotes ( they will come with another antenna ) get a copy of the CM4200-VD install guide.  It will tell you how to program the remotes to your R/S control unit. 

It would also help to look for the Bypass unit ( under the dash somewhere ) that was installed with the CM4200.  Get the brand and model number.  That info will help a lot.

My remote does not indicate anything, but I have located the installation manual for the type of unit that's installed on my car. https://nustart.ca/support/NUS-Install.pdf.

As for the remote, I have placed an order with the manufacture for replacement remote and I'm hoping to recive it anyday. It has AM antenna installed on it, that's for sure.

Thank you again for all the replies.

Hi,

Can someone please help me now. I have the new remote now for this unit. I need to understand this bypass thing so that I can program my new remote to the old unit.

Please and thanks!

Here are the steps to program the remote(s) to your R/S system.

1. Cycle the key in the ignition from the “Off” to the “On” position 5 times. This must be done within 7
seconds.
2. After the 5th cycle, you will hear the parking light relay “click” and see the parking lights flash once. Be
aware that the vehicle’s “chime” may prevent you from hearing the relay “click.”
3. Once you hear two relay clicks along with two parking light flashes, the system has just exited remote
coding mode. (Note: If no remotes are programmed at this point then the CompuStar will automatically
enter Valet Mode.)
4. Right after cycling the ignition the 5 times:
  a. 1-Way Remote: Tap the lock button on the remote for a split (0.5) second.
  b. 2-Way Remote: Tap button I for a split (0.5) second.
  c. 2-Way Spread Spectrum Remote – This remote requires a different procedure for programming
    I. Remove the (+) positive side of the battery from the remote.
    II. Follow steps 1 to 3 above.
    III. Slide (+) positive side of remote battery back into remote.
    IV. Do not press any buttons on the remote as it is syncing with the antenna.
    V. Once the remote receives a page back, the 2WSSR is ready for use.
5. After tapping the button on the remote, you will hear the parking light relay “click” once to indicate that it
has accepted the remote. If you have other remotes you must program them at the same time, repeat steps 4a
or 4b for each remote you have.
6. After a few seconds you will hear two relay “clicks” and see two parking light flashes and remote coding
has been completed.

If the system was working and nothing was removed or disconnected or changed then it should all work once the new remotes are programmed.

Ahh, smart key.  The CM4200 relies on seeing the IGN1 wire going to +12 volts when you turn the cars ignition switch to Run to get into programming mode.  The corolla with smart key doesn't have an ignition switch to turn.  Sorry, I'm a little dense sometimes. 

Here is the way I would get around that.  Make a jumper wire that is 18 - 24 inches long with alligator clips on either end.  I also have a fuse holder with a 5 amp fuse in the middle of that wire.  Obtain access to the CM4200 module with it still connected to the car.  You are going to carefully strip some insulation off 2 wires on connector CN1.  These are heavy gauge wires.  The Red wire at pin 1 will be supplying the +12 volts.  The Green wire at pin 7 is the IGN1 wire.  Attach one end of the jumper to the red wire ( making sure the other end is not touching anything! ) and then touch it to the the green wire 5 times, leaving it clipped on the 5th time.  That should be the same as Step 1 and get you into programming mode.  Continue programming the remotes.  After you are done, disconnect your jumper carefully and use quality electrical tape the wrap the two wires up securely.

Thank you very much Kreg. I will give that a try today. It does not seem too difficult and hopefully things go well.

I will post the results.

Kreg357, you're pure GENIUS! THANK YOU!

Just finished doing as you instructed, and wola! I got my remote programmed. However....I have one problem. I can lock / unlock doors with the remote, but when I attemt to start the vehicle, I can see that it attemtps to start the car 3 times, before giving up. I can see the Green LED lit 3 times on the Push Start Button, I hear the chrim three different times, but car does not start.

The bypass unit that I have on this car is iDataLink ADS 128. Can you please help? I don't have a clue what to look for.

Thank you again!

Using the IDatalink AL CA module on the Toyota Corolla with Smart Key there are some restrictions.  This is an exerpt from the install guide.

IMPORTANT:
1-NO TAKEOVER AVAILABLE. UPON OPENING VEHICLE DOOR ENGINE WILL SHUTDOWN.
2-ALL DOORS MUST BE CLOSED TO REMOTE START VEHICLE.

So to remote start your car:  Make sure all the doors are closed.  Also when you are ready to enter the car, it will shutdown as you open a door and have to be restarted.

Did you have all the doors closed when you tried to remote start it?   If yes, did it try to crank?   There is a light on the IDatalink module that will blink and give you an idea of where the problem lies.  Flashing green during R/S is good.  Here is a link to the IDatalink web site.  Look up you car and select the guide for the ADS AL CA.

I tried all possible options.

1. I kept the smartkey in the car and attempted to start the car with all 4 doors closed...no luck

2. I removed the smartkey, stood about 20ft away from the car, with all doors closed, and tried starting...no luck

3. iDataLink module flashes green when I attempted start

Sorry, forgot the IDatalink web site link:   https://www.idatalink.com/helpdesk/

It is possible that the no start problem is that the Tach must be re-learned on the CM4200.  The CM4200 will blink the parking lights to indicate a problem after a failed start attempt.  The codes are at the back of the CM4200 install guide. 

Another possible problem is that you are in valet mode.

Keep us posted...

First, thank you guys for helping me on this. Much appriciated.

Hi Kreg...these are my symptoms

I can lock / unlock doors, when I push stat button from the remote, the parking lights flash and I see the remote starter attempts to start the car, I can hear the clicks few times inside the car, but it does not blink parking lights to indicate the error code

I have performed factory reset on the iDataLink module as per install guide, but it's funny...after resetting and reconnecting all connectors, the green LED goes back to flashing green, without me having to do anything. I tried resetting the module several times, but same result.

When I try to reprogram, I don't seem to get the result that I'm suppose to. The LED is supose to turn solid RED but never truns red and keeps flashing green.

After a reset to the IDatalink module you must set it to Data Mode or Standard mode with the instructions at the top of page 8.  To deciede if you need Data or Standard look at the black 4 pin connector on the ADS AL CA module.  An intact harness going to the the CM4200 CN7 means Data.  Three wires from the IDatalink black connector going to +12 volts, ground and CM4200 CN2 pin 4, black wire means Standard mode. 

After you set the mode then you can re-program the module to the car with the instructions on page 9.

if you have no programmed tach, it wont start. do you have the two way remotes?

if you do, if a failed rs is present. the bottom corner will indicate ER-01.

you can go into programming and try to change it to voltage sense. if the car start, run a tach wire and program it by starting car, hold brakes and press start on the remote.

Just so we know which CM4200 brain module you have...

Does the CM4200 module have the 2 dip switches ( for selecting run time and Volt/Tach mode ) and the Tach learn button on the side with the cut jumper wire ( Auto/Manual ) and the antenna connection?

Hi Kreg,

Yes, I do have CM4200 unit exactly like you described.

I found something. I traced all wires going from iDataLink to Push Start Switch. Accoding to Install Guide, I'm only suppose to have two wires going to switch. One Blue/Red (Ground) and other Blue / YELLOW.

However, I have GREEN/ Red,  Gray/Red & Gray / YELLOW all going to switch. Could this be the cause? I'm still having problem reprogramming the iDatalink. I can erase it, choose Installation mode selection, but can not program it. The unit doew not flash RED or Green while programming.

What do all of these wires do? There is no description for any of these.

Oh, I have a FM Antenna with 1way FM Remotes.

The original unit came with AM Antenna, but I replaced it with FM Antenna and 1way FM remote. They were all compatible.

You probably have an earlier version of the IDatalink firmware on you module.
Try this procedure.

Make sure only one key FOB is present in or near the car.
1   Open Factory key fob.
2   Remove circuit board from key fob.
3   Remove battery from circuit board.
4   Place circuit board in front of push to start button.
5   Push start button twice [2x] to ON position.
6   LED on ADS AL CA will flash GREEN and RED.
7   Wait, LED will turn solid GREEN for 2 seconds.
8   Module Programming Procedure completed.

This procedure uses the Gray/Red, GREEN/ Red and Blue / YELLOW wires from the module to the Push To Start button.

This thing is driving me nuts....Thank you so much again for helping me on this. I truly appreciate it. It seems that my luck is not with me.

I can't get it to go. I tried the steps you listed above, but the LED never seem to turn RED and just keeps flashing green. I waited at least two minutes, but it never changed it's colour. I even retried all steps from doing a factroy reset, selecting the mode (i.e. Data) and reprogramming. The programming step is the only step that gave me inconsistant result.

The funny thing is that when I attempt to start the car with remote starter, the iDatalink LED flashes green, and that's what I'm suppose to see. The car flashes it's head lights and then after few second all head lights (day time running lights) turn on, so I think unit thinks that vehicle is running, but it actually never starts.

When I push the stop button from the remote start remote, it turns off the head lights. Go figure. So, where do you think the problem lies? Within wiring, CM4200 brain or iDataLink?

did you check if you had the correct firmware loaded?

the problem lies in the idatalink. the idatalink is designed to carry out the start sequence.

plug in idatalink press programming button twice (if your in w2w mode)
press and hold programming button. it will stay solid green.

hit the push start button twice, LED on idatalink stays green, push push start button again to turn off.

idatalinks diagnostics indicate if its flashing green when the ignition is not on, there is a fault on the status output. to prevent this, try disconnecting the GWR BLUE/WHITE.  and try programming from the start.  when your done programming, reconnect this wire.

Hi tedmond,

I don't know what firmware is located on my iDataLink module. I don't have the cable to verify or upgrade.

I did as you instructed, but had no result. I'm not sure what you meant by w2w mode. I performed reset, chose the mode and then tried your method, to no avail.

As for the last line when you said to disconnect GWR..not sure what GWR is.

are you running w2w (wire 2 wire) or data?

data is when you use a 4pin connector that has BLACK,RED,BLUE,WHITE.

wire to wire is when you connect a majority of wiresfrom the idatalink to the the rs/alarm unit. such as door trigger, trunk release, lock/unlock, etc.

i will always recomendt w2w. you will only have to disconnect the GWR blue/white from the idatalink if your not using d2d menthod.

I believe you said it was D2D mode.  That means you set the ADS AL CA to one blink after a reset.  Are you removing the IDatalink's harness as per the directions during a reset?  Don't want to add and check lights to the situation.

We really need to find out the firmware and version on your module.  The Compustar 4200 with FM remotes and IDatalink module are top shelf items and worth keeping.  Either going to a Best Buy and asking the tech to check it for you ( carry it in, in your hand ) or buying a cable on EBay.  Just don't update it or change it.  That will necessitate a lot of wiring changes and really complicate things.  With that info a simple call to ADS tech support will get you the install guide number.

Just for grins, try this.  Place the Toyota FOB circuit board without battery next to the Start button and try a remote start.

Also check the CM4200 dip switch to see if you are in Tach mode or Alternator mode.  If you are in Tach mode, start the car normally and after it gets to a normal hot idle, press the Tach learn button on the CM4200.  One parking light flash is good.
