Why is the vehicle not responding?

Sat, 18 Jul 2026 14:20:58 +0000

I have a Fortin evo all, a evo start lte, and also shock sensor. I’m getting feedback from the car which shows up on the Evo start, but commands sent aren’t working, and when the evo alarm goes off the vehicle alarm does not. I was hoping you could tell me if there’s some wiring that I’m not aware of, or if the process with the dcryptor is wrong? everything seemed to program correctly. I used the CHR7 T-harness and it’s on a 2018 grand Cherokee. What am I missing?

I read for Evo One if I don’t use the T harness and proceed to install directly I require to install 2 diodes for the pts and a relay for the parking lights, my question is the THAR-ONE-MAZ5 have the diodes included and the relay? I see a small relay not sure if that for the pts or lights, I will appreciate if you can explain. THAR-ONE-MAZ5

Mazda cx 30 shuts off after pressing the brake pedal

Fri, 03 Jul 2026 20:07:31 +0000

I recently purchased the THAR-ONE-MAZ5 with the EVO-ONE remote starter and immobilizer bypass module for my 2023 Mazda CX-30. I installed everything following Manual #99841, but I’m experiencing an issue.

Problem 1: Vehicle Shuts Down After Takeover

After remote-starting the vehicle using my OEM key, I follow the takeover procedure (Page 11 of Manual #99841). However, as soon as I press the brake pedal, the engine shuts off.

Problem 2: A/C & Accessories Not Working Properly

Additionally, most accessories (including A/C) do not turn on during remote start. Even if I manually activate the A/C after remote starting, I can hear the compressor running, but the blower fan does not work nor the A/C interface screen.

Module locking itself

Sat, 18 Apr 2026 09:38:38 +0000

I installed this evo all in my corolla with the TOY13 T harness back in 2022, and it worked flawlessly until maybe a year ago. The first odd issue was that it randomly started itself twice one day without me ever pressing the RF remote or activating it with the OEM remote. It didn't do that again after so I didn't think much of it. Then this year I found that my car was unlocked with the trunk open. After that instance I removed the starter and made sure to isolate all the wires that weren't used on the harness (Although this gave me no issues after 3 years), and I even did a master reset and reprogrammed it to the car. After maybe a month I noticed that the car would now start to randomly lock itself (again without me pressing anything on the remotes), and this has been the happening more frequently now. This is very odd and frustrating as the module was working perfectly for 3 years.

system worked flawlessly but only once.

Fri, 10 Apr 2026 12:38:02 +0000

i have just installed my evo-one with the gm3 t harness, and 942 rf kit on a 2015 chevy silverado 2500hd with standard key and onstar. i got the remote start and locks to work during testing but after i buttoned up, being careful not to stress any wires, my locks are no longer functioning. the remote says it worked, i hear the relays clicking, and see the parking lights flash. if i try to start the truck it will successfully start and run for about 3 seconds before shutting down. i will get several flashes of the parking lights but then it will not try to start again. i have counted 2 and 4 flashes after a failed remote start and i have even seen "service theft detterent system" on my dash a time or two after a failed start.

evonone toy16 in 2024 Tacoma Manual transmission. when the truck sits for about 10 mins it will not start remotely.

Wed, 25 Mar 2026 19:36:46 +0000

i installed this evo one back in Nov. of 2025. when i originally looked into installing the remote starter i asked tech support if the evo one could do a 24 tacoma manual trans. and was told it was no problem. now when i look up the vehicle it shows that the evoone will only work on an automatic transmission for this application.

is there a known issue with the firmware for this vehicle for manual transmission?

any info is greatly appreciated

thank you,

2018 Tiguan (STD KEY) with THAR-VW6 sending constant voltage to ignition switch

Fri, 20 Mar 2026 18:44:37 +0000

I have a 2018 Tiguan MK2 with a standard key and automatic trans.

I had installed the THAR-VW6 and had my EVO-ALL on firmware 64.10.

With the T-harness installed, even without the EVO-ALL connected, the car's switch is receiving a constant high voltage and the vehicle will start with the key in the on position and pressing the break without turning the key.

This is also an issue with the vehicle's auto stop-start feature.

Because there is a constant voltage being sent from the ignition switch, the car will send an EPC error and the engine will not auto stop-start due to error.

I've tried turning on Push-to-Start; no change. in fact, this option turned on makes it so the car doesn't even try to start with the LOCK-LOCK-LOCK command.

Dcryptor limit reached for this vehicle. Reset help?

Sat, 14 Mar 2026 19:17:54 +0000

I have an EVO-ALL and I am trying to setup my CarLINK ASCL7 on my 2019 Toyota Camry PTS to work with it and I've had to change some settings and swapping around the wiring harness. That still doesn't work but the Dcryptor limit has been reached for this vehicle. I need help resetting it.

Also if anyone knows the correct flash manager settings and wiring harness setup that would be extremely helpful.

Request for CAN Wiring Diagram – Start-X Kit (Dodge Challenger 2015–2017)

Mon, 23 Feb 2026 19:02:57 +0000

I recently purchased a Start-X remote start kit for my Dodge Challenger 2015–2017 from Amazon. After opening and installing the kit, I discovered that some wires are missing — specifically the CAN bus harness that connects from the OBD-II port (pins 6 and 14) to the module.

I contacted Start-X support, and they kindly offered to either send the missing harness or replace the kit. However, I have already shipped the kit overseas, so returning or receiving replacement parts is unfortunately not a practical option for me.

While researching, I found a Chrysler wiring document that explains the module side (white connector) CAN wiring, which was very helpful. The missing component appears to be a 2-pin CAN connection from the OBD (pins 6 & 14) that transitions into a 5-pin CAN connector going into the module. https://cdn02.fortin.ca/download/97651/evo-all_ig_rts_bi_chr6-7-300_2011_pts_b_97651.pdf

I would like to build the missing harness myself, but to do so safely and correctly, I need the wiring diagram or pinout configuration for the module.

Module Serial Number: 001A07 682508

Could you please provide the CAN pinout diagram or technical guidance for this specific module so I can fabricate the harness properly?

Thank you very much for your assistance.

EVO-ONE With RFK411 Kit will not enter remote pairing mode

Mon, 12 Jan 2026 04:31:05 +0000

Good Day,

I have managed to successfully install The EVO-ONE into my 2011 Kia soul. Standard Key, With immobilizer using the T-Harness.

The Key bypass has been successfully programmed and the vehicle starts/stops normally, however, when trying to initiate the remote key pairing for the RFK411 kit, I cannot get the antenna to initiate the sequence.

When turning the ignition on/off/on the antenna light does not become blue, and if I tap the brakes 4 x, there is no flashing light either to get the unit to go into pairing mode. Have tried re-setting the Evo-one and again, they key programs fine but I cannot initiate RF pairing mode.

Thank you,

Cheers,

Matt

Subaru Legacy Rear Defrost (Aux1)

Thu, 11 Dec 2025 02:11:33 +0000

015 Subaru Legacy std key SUB1 harness installation. EVO-ONE. I'm trying to turn on the rear defrost when the car is remote started. As instructed in other posts, I tied the AUX (yellow/black) wire to the negative wire identified as the defrost trigger on WireColor (behind dash fuse box, pin 26, purple / green). I then set option 25 as pulse (0.5). When the car starts there's still no sign of the rear defrost being enabled. The button can still be toggled manually but does not come on at start. Even though other areas had this listed as pulse, I did go through the latch settings just in case but none worked. Am I missing an additional step here?

Subaru Legacy OEM Remote Delay

Thu, 11 Dec 2025 01:49:32 +0000

2015 Subaru Legacy std key SUB1 harness installation. EVO-ONE. Using OEM remotes for starting (lock-unlock-lock). Car starts as expected and everything related to the start is working as expected. The only issue I’m having is with the OEM remote response once the vehicle is running. When the car is off, remote responses (lock, unlock, trunk) are quick and immediate. Once the car has been remotely started this changes. The command still work, but take multiple button clicks and responses seem random. I’ve been unable to figure out how to correct this. Any help would be appreciated.

Remote start not working on evo one with THAR-ONE-HON5 T harness and 942rf kit

Thu, 04 Dec 2025 05:42:02 +0000

I initially was able to successfully connect my EVO one to my 2009 honda accord with the HON5 T harness. The OEM key fob worked fine starting the car (I programmed it to lock, unlock, and lock), then I went to install and pair the 942 RF kit. After pairing the 2 remotes, it was able to lock and unlock the car just fine, but when I pressed the (+) button twice to check the status of the car, it gave me the wrong status beeps (it was telling me the car was unlocked when it was actually locked). Next I tried remote starting from the 942 remotes and it wouldn't start, it would give me the green confirmation saying that it started, and then later beep/flash red that it failed to start 3 seconds later. Then i tried using the OEM fob to start (which previously worked) but didn't work as well.

Both the module and antenna are up to date. I tried fixing it by reflashing the evo one with the same settings I used in the beginning, and reconnected it to the car. I made sure all the connections were intact (including ground), and even tried reprogramming the module to the car, which seemed to be successful according to the light sequences outlined in the installation guide. Still not working after this. I also tried the master reset (https://12voltdoesit.com/uploads/docs/Fortin/EVO-ONEMasterReset.pdf - *I used the bypass side*), which didn't do anything. I removed all the connections for now while trying to resolve the issue.

Do you make a system for a 2022 Subaru wrx, key start, manual transmission?

Thu, 04 Dec 2025 03:27:09 +0000

On your website, I put in my car information 2022 Subaru wrx key start manual transmission, it shows systems that are compatible but do you guys make a harness that is compatible? I don’t see one and the instructions for it I believe are only for an automatic. I also went to program the evo one and the only option for the 2022 wrx is for a push button start, no key start. I purchased the evo one 942.

Evo One randomly stopped starting the vehicle and I don't know why

Mon, 10 Nov 2025 14:47:48 +0000

I have been using my Evo One in my Mitsubishi Outland push-to-start for almost 2 years with no problems. Now, the last couple of weeks, it won't start the car. I click the OEM fob lock 3 times, the outside lights all light up like it is going to start. Even the dashboard lights all light up like it is going to start and the radio comes up, but nothing. After a few seconds everything goes back to being dark. I can still jump in the car and start it manually just fine. Any thoughts on where to start troubleshooting this?

2020 Honda Civic Starts But No Power to Head Unit and SRS Airbag Error

Wed, 01 Oct 2025 19:52:29 +0000

Installed an Evo-One with Evo-Start on a manual transmission 2020 Civic Sport. Can start the car just fine with the OEM remote or the app but when using either there is no power to the head unit and there is also an SRS airbag alert. This all resets after restarting the car but I am wondering how to keep this from happening. After doing some research i believe ignition 2 powers these accessories, is that so? Checked that function 2 is set to mode one which is supposed to be correct for this vehicle I have double checked all connections and all are good. Have used a multimeter and both ignition pins with pink and white wire and both are receiving 12 volts when started. Also is there a way to fully takeover the vehicle without shutting it down first or is that just a Honda thing with no workaround? Thanks

I've installed the EVO ALL-LTE w/ THR-VW3 and TB-VW, using guide #65601, on a 2018 VW JETTA (standard key). I've checked the wiring over twice and then begun programing, but there is a problem in step 14 as the yellow LED stays solid, the red LED never turns on and both red and yellow LEDs do not alternate at the end of this step, I've used the TROUBLESHOOTING GUIDES step-by-step guide type tool, with no luck and now i have reached the Dcryptor's limit for this car after having attempted the programing several limes over.

Help please.

20 conductor harness wires too short??

Thu, 10 Jul 2025 03:22:35 +0000

I don't understand how people are installing these units, I can't find any way for the wiring to reach the passenger side kick panel. The wires are at least 1 foot too short on the 20 pin connector so is there a trick to the install or do I need to buy an extension? I was hoping to not splice in sections of wire but I will if I have too.
purchased the EVO-FORT1 standalone with THAR-FOR1

Wires that are too short are A17-19 on the 20 pin connector "A"

thanks

RFK-442 - Evo-all install without RFA2A

Mon, 10 Mar 2025 20:53:56 +0000

Hello. I am trying to install an EVO-All with GMT1V2 T-harness in a 2014 chevrolet cruze. (remote starter is programmed and works with OEM remote) I have an RFK-442 kit I would like to install without the RFA2A adapter. I have 12v and ground present at the datalink from the t-harness. Am I wrong to believe that the antenna kit can wired into the Datalink plug? I have wired it as such, When I plug in the antenna. the LED will light for a second. but when I follow the RF kit learning prcedure for the EVO-All. the antenna LED does not respond. Is the RFA2A really required? Thanks

Can I use the A14 switch option for the parking light control when configuring the EVO-All?

Mon, 03 Mar 2025 18:33:49 +0000

Guide says for parking light control the A14 brown/white wire needs to be tied into the light blue wire of the second BCM connector pin 8. Didn't know if the A14 was turned on when configuring the module that would negate needing to tie into the pin 8 second connector on the BCM.
