Transport mode?

Post by CrashTestDummy »

I read over on the SS list about the ability to put them, and several other Holden import models into transport mode so that the battery drains at a slower rate. While I purchased our Caprice to replace the previous DD, I don't really 'DD' that much these days. So, the Caprice sits in the shop for a week, or two, at a time. With the weather the way it's been lately, I'm even less inclined to take it out for a drive around the block. I was wondering if anyone knows if there's a 'transport mode' for the Caprice, and if so, is it enabled the same way it is on the other models? Thanks.

Good question!

When I bought my PPV (back in 2011; fresh off the lot), the dealer's tech showed me a blue plug in the battery compartment. He mumbled something about it being unplugged for shipment. I watched him hook it up just before I took the test drive. Could this be related? I never really thought about it since then. And never bothered to research it any further. I'm curious now.

I leave my car in storage for weeks and sometimes keep a BatteryMinder attached to keep it charged up. That's all I've ever done. In Engineering Mode, the car often says the battery is at 60-70% even after leaving the charger attached for long periods. It isn't until I drive it for a while that it comes up to 90% or above. I'd also like to know what computations are used to determine this percentage.

I believe that the larger blue plug on the passenger side battery is the 50 amp feed for the upfitter harness that is located under the glove box, behind the passenger side kick panel.

The blue connector behind the passenger trunk carpet is the connector for transport mode I know it affects cars with the auxiliary battery but I do not know how to fix cars without the auxiliary battery I don't believe it has any impact on the primary battery

not sure if it's even a normal setting....why not just invest in a Battery Tender type of charger?

Just about everything we have is on a battery tender. We have 3 each 4-port units, a 2-port and a single-port one, so I'm very enamored with the Battery Tenders.

So how do you hook them up with dual batteries in the trunk?

GM actually recommends transport mode for vehicle on lots to save the batteries.

General procedure here:
http://gmupfitter.com/files/media/photo ... in_121.pdf" onclick="window.open(this.href);return false;


2011-2015 Vehicle Procedure
To turn the Transport Mode On/Off, it will be necessary to start the vehicle, activate the
hazard flashers, press the brake pedal (automatic transmission) or clutch pedal (manual
transmission) then press and hold the Start/Stop button or turn the ignition key to the crank
position for 15 seconds. (The engine will turn Off on push button vehicles.) The same steps
are used to turn on the feature.

Who's gonna try?

EDIT: I tried it, did not work. Nothing, nada.

Edit 2 : Oh apparently the 2014's have it:
http://sandyblogs.com/techlink/?p=2757" onclick="window.open(this.href);return false;

Transport Mode

All 2014 model year vehicles leave the assembly plant with Transport Mode active to save battery power. The Driver Information Center (DIC) will display Transport Mode On when enabled.

TIP: The driver’s express power window learn procedure may need to be performed after turning off Transport Mode. When in Transport Mode, the remote function will be inoperative. As the Remote Keyless Entry will not allow remote unlocking of the vehicle, the vehicle will need to be unlocked with the mechanical key.

To disable Transport Mode:
1. Turn on the hazard flashers.
2. Apply the brake pedal.
3. Turn the ignition key to the Start position and hold for 15 seconds; continue to depress the brake pedal.
4. Transport Mode Off will display in the DIC when disabled.

Apply one battery tender to each battery. The batteries are not linked when vehicle is shut down and key is off. Unless you never use the car or have after market equipment wired to the acc battery, the parasitic drain on the accessory battery should be equal to that of a pre-computerized vehicle....basically very little.

That being said, I think the majority of the people on this board really have no use for the aux battery. The only practical use I can think of would be to hook a power inverter to the acc battery and run it for a long time with the engine off without fear of being stranded. For the majority that do not have a bunch of after market electrical accessories, I would ditch the accessory battery for weight saving. I plan to do this once the battery goes bad.

Hmm, if the batteries aren't connected at power-off, I'm thinking I can just hook the tender to the primary battery. The main idea here is to help the car start without a big load on the battery at start, and the charging system after start.

I'm thinking that an A/C converter hooked to the secondary battery might be a nice addition, but haven't settled on a decision there yet. I'm definitely converting the batteries to AGM type sooner, than later, to get all that acid out of the back of the car. If I keep both batteries, I may go with a pair of Brailles, or something along that range. If I abandon one battery, I may still go with the lightweight batteries, but again, haven't settled on that decision, either.

Because of the occasional rodent in the shop, I usually open the hoods of our cars kept there (keeping the little monsters OUT of the hoodliner). Does anyone know if I can simply connect the tender to the battery terminal under the hood and ground the other to the ground post on the fuse box and still maintain the battery in the back?
