I have a 2015 2500hd. Ltz/z71.  Diesel..   Lately with cold weather when using remote start. Will only try to start. Like if you just hitting key to turn over a little.  It will keep doing this until I unlock truck and put key in and start truck.  Does this only when left overnight or long periods.  Remote works if done in short time after running..   Asked dealer.. Didn't know until I take it in.   Any suggestions?   Thanks.  Ron.

Remote start won't work if there is any CEL/MIL active.

 

Also won't work if the hood is not closed, or if the key is in the ignition. 

 

 

Glowplug failure will set a CEL/MIL and cause no remote start.   

When the key is used after the remote doesn't work, is the light on?

Its not the remote battery. 

Might be a CEL/MIL, but I doubt it - as the remote start would probably not make any attempt. 

Hood switch problem - remote start would not make any attempt to start. 

 

Any system that would disable the remote start would prevent the starter from engaging. If the starter is engaging, then it is not a "computer" issue. 

 

If it only happens when its real cold out, I would strongly suspect the battery. 

 

The dealer will not help you in any way without receiving monetary compensation, and you can not blame them for that. They are there to make money, not to help you out for free. 

 

I would take the rig to a local auto parts store, and ask them to test the battery (free). 

 

If the battery is bad (probably is), then I would got to Walmart and have them install some "Value Power" batteries. Cheap, and pretty good batteries. If you are rich, get some Optima batteries.

Be sure to 'separate' the batteries so they are load tested individually.

 

If one needs replacing, replace them both.

(Find another job for, or sell, the one good one - if that's how things turn out)

? On the dual battery setup system of the diesel trucks....Is one battery more dominate than the other for certain/separate circuitry component features ? Or are they combined to handle it all ?

 

Like with this question for example; One for the remote start system, lights, all defrosts or AC if hot out, etc... and the other handles normal start-ups with the key, dash circuitry and whatever else might be on that circuit + whatever's been left on by the driver switch wise.

      Did you ever get this worked out? Mike is doing the two start thing now too. This is after a new camera back in December.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
