Hey guys, got my new car running a couple months ago. It's a terminatorx with the can io module, worked great, only problem was my driveshaft sensor wouldn't read. I needed to rewire some of my outputs, 10awg to fans and pumps, so I did that and found 1 of my splices to the driveshaft sensor was bad. So I fixed that and got all my other stuff done, also added flex sensor to the ecu not the can module.

Turned it on and only my trans temp sensor and air tank sensor weren't working, havent checked driveshaft yet. Ran through all of my outputs and everything is good, checked 5v to the tank sensor and had no 5v. So I left it unplugged and started going over everything in the software to make sure it was all in the right places. Come back switch it on and now I have no inputs on the CAN. Unplugged all of the sensors and none have 5v power, they all seem to be grounded according to my voltmeter. I remember thinking my trans temp sensor just works off sensor ground and I have that but it still doesn't work.

So I did some messing around, making sure the module pins were correct and all seated and it's all fine. So I made a jumper and went from my power tap connector and back probed 5v to my back pressure and coolant pressure sensors 5v circuit and every sensor started reading, including the trans temp that doesn't get 5v.

I'm a bit confused with the temperature sensor, but I have no problem permanently running 5v from the terminatorx to the can sensors. I'm just concerned why this happened, the only sensor wires I touched were for the driveshaft. I know the can gets its power and ground over the can circuit and then I assume it creates its own 5v outs? So if it's turning on it should be putting out 5v to the designated circuits? I don't want to hook my ecu 5v to it and it then mess up the ecu some how.

Anyway sorry for long post, just confused and thinking through text. I ofcourse appreciate any thoughts, ideas, or feedback.

 

I myself keep the 5v sensors on the can module powered by the 5v+ power outputs on the can module (pins 5, 7, 10, 32)

I also keep any sensors on the can module grounded through the ground pins. Some are noted as 5v and some are just "grounds" which I would assume would be for higher voltage sensors. I havent used them yet.

as a side note, I have smoked the i/o FET's on a terminator. Not sure how I did it, was fine one day and the next it wouldnt sync. Holley warrantee'd it very quickly, thankfully.

 

mine was the same, I had all the can sensors getting 5v and sensor ground from the can module. Then out of no where none of them were reading, checked it out and none of them are getting 5v from the can module. I guess the 5v circuit inside the can stopped.

I added 5v from the power tap to only 1 of my can 5v circuits, just teed it inline. And now all of the sensors are working, so all the 5v inside the can module are still connected to each other. The can module just isn't outputing the 5v. It is odd also that my thermistor wasn't working, but once I put 5v on the can 5v out circuit the thermistor started working. The thermistor doesn't have 5v, so it's like the can module couldn't see its resistance unless the 5v output has 5v on it.

Do you know if the can module creates its own 5v? I would assume it does, but irdk. I don't want to have to send it in to holley when it's working perfect now, it also runs 8 outputs that I need lol

 

yeah sounds like it needs some warranty work honestly.

 

I emailed holley support yesterday to see what they say. I just hate to send it out when it's working fine, minus the 5v output. But I'd also hate to mess up my terminatorx ecu some how. So far 1 person wrote back to my thread on the holley forum, and his can io module did the same thing, so maybe this is more common than we know. I'll let you know what happens, I bought my can module back at the end of March.

 

A Holley problem, unheard of. 😂
Well hopefully it gets worked out, but everyone I read about, just keeps making it harder for me to buy, or push their product to people.

 

Suit yourself, thanks for the help.

 

bro send it in while its still in the first year. its almost a no questions asked thing

re: holley quality... it is what it is. the unpotted terminator cant take the knocks the HP and dominator can. i dont know if the can module is potted or hardened. I would have to assume not given it's price.

it actually kind of amazes me no one is trying to take holley's lunch. they have the plug n play LS market on lock. the UX is pretty noob friendly and theres a **** ton of support. onboard trans and boost control seals the deal for most of us using it.

yes i know very fast people on stock PCM's but they have like 20+ years of tuning and hotrodding under their belt.

but the market is massive and to have only a few plug n play choices is a bummer.

a local subaru guy tells me Link ECU is coming out with a competitor to the terminator. same price point but more i/o's ....no idea what the UX is like tho. if it's megasquirtish, hard pass

 

like I said I sent an email to holley last Friday, still haven't heard back but I didn't expect to. I have an update tho and it's not a good 1, yesterday I started getting smoke out the exhaust and found my scavenge pump wasn't on. It's turned on by the can module, so I killed the engine, look at my fuses, then turned it back on. Scavenge worked fine.

Now today same type situation, was doing some idle tuning, turned engine off and made some changes. Fired it back up and noticed my temp gauge just continued to rise way past it normally sits. found the waterpump and fan weren't coming on. Shut it down, waited a second, turned key on and they were working fine.

So it seems like the can module is going crazy at times and not turning on the outputs. I'm gonna try to call holley in the morning and see what they know about it. I'll let you know what happens Doug!

 

I have always had fantastic support from them on the phone. Sometimes it take a 15-20 min wait time, but I normally throw it on speaker phone and work.

 

Update I ordered a replacement can module from holley, removed my jumper wire and plugged it in and modified my tune for this module. Everything works like a champ. Hopefully I can get my old 1 fixed and have a spare.

 

Hopefully you can get it fixed. I'm sorry if my first reply wasn't great, but I've also delt with some broken Holley stuff, and am still a little salty with them. I'm by no means a big Holley dealer or anything, but as someone who promotes their product, tunes their product, and is a stock owner, feel they are not doing right in some instances. Please post up your outcome and experience once you get there.

 

I finally got tired of waiting for email support, so I called and really wasn't on hold as long as I figured. They basically said it has a 3 month warranty but they usually will cover stuff for 12 months. They emailed me a prepaid shipping label, which I wasn't expecting, and said they would look at it and see if it can be repaired. If not repairable they will send me a replacement IF they decide to warranty it. I think they can hook up to the normal ecus and see a runtime, not sure about the can module but its very low on hours..

So now we wait, definitely glad I went ahead and got another 1. I'd hate to have it down for however long it takes them. I'll let you guys know what happens.

 

be sure and register your products to get the full year warranty

90 day warranty SMH this country is fuxxd

 

Just to put a fat lady at the end of this show, holley sent me a replacement can module and I got it today. Now I have a spare if it ever happens again, thank you guys for the help.

 

That's awesome to hear. I'm glad to hear that. I really hope they help warranty guys out as much as possible.
I'm going to swap mine over to Holley finally, partially because I tune Holley stuff, and well, it just looks a little better if I am running it. I'm hoping I don't have issues, or it will go back on a P59. I love all the capabilities of Holley, but time will tell for me anyway.

 

Putting a terminatorx on my Mazda truck was the best money I ever spent. With this new car it was a no brainer to go with holley again. Kinda wish i would have sprang for the dominator but its still an option down the road, and most of the wiring is all ready in place.

I got my new ptc converter in the other week, was adding a brace to my submarine belt and caught the carpet on fire lol. Burnt the kirkey seat cover and most of the console, luckily i seen it was blazing. The carpet was pretty jacked up, this whole car was jacked up, I should start a build thread. I was also wanting to go with a 17" seat instead of an 18" so like most things it worked out. Hopefully the roads dry up and i can drive it tomorrow.
