Typically just the engine is not ready for that feature to be activated. My Mercedes would give me a similar warning. Also would have come up if oil was too low on that car.

 

We just acquired a gently used 2016 Durango Limited with 40,000 miles on the odometer. Prior to accepting it from the seller, we had it thoroughly inspected by our competent and reliable local Dodge dealer. They fixed a few minor things like power seat calibration (never heard of that), minor battery-related fault codes, and "hood switch out of adjustment". The dealer pronounced it to be a solid car. We picked it up, completed the sale, all is well.

The next day Mrs. Futterman drove it to work. The Auto Stop feature caught her off guard. Neither of us were expecting / aware of its existence on this vehicle. I am familiar with the concept, and over the phone I explained that it's "normal". On the way home, she said she got the warnings illustrated by the photo above, and the Auto Stop subsequently stopped auto stopping. ?

The message and light have been present ever since, which is about a week. I don't really care that it doesn't work, but I don't like knowing why it's not working. Also feel like we would like to have the option of using it when we want to. Would appreciate any insights into potentially the first and most common causes.

Thanks!

 

The battery probably needs replaced. It is located (I believe) next to the main battery

 

Hello I have 21' Durango with that same message I not understanding there's a battery just for that feature?? Or the main battery yr saying there under pass, seat I looked there no trap lid or anything how do I access these battery's??? Please help I don't want my daughter driving around if something not working or is it OK if that feature not work? I could use any help us dodge owners can offer

 

Thank you. Are both batteries located under the front passenger seat? I noticed the battery is not in the engine compartment and there's a cover on the floor under that seat.

 

Hello I have same message on my 21' Durango stop start not working all of sudden, yr saying there a battery just for that feature or n the engine battery under front passenger seat? I looked only see white plug mounted order each seat with wire harness to it but I not understand how do you get to these battery? Please Help

 

Very common for FCA’s aux battery to fail

 

yes. it is located under the front passenger seat

 

I bought a 2019 late in 19 and the battery for the start stop was bad. they replaced it. Some symptoms as yours

 

Thanks for your helpful replies!

 

Has anyone figured out a real fix for this issues or a real reason behind it?

 

Looks like it was a bad battery....

@ Am3er:
Typically, this SS issue is caused by a failing SS battery. The main battery can also be on it's way out. Year/model/engine for your Durango please. Is it by chance, still under warranty?

As general info, once the bumper 3/36 expires, the powertrain warranty, and most service contracts don't cover batteries, treating them as a wear item like brakes and tires, etc.

Anyone seen this? Any resolve for the issue? I just got the message on Sunday and it has since went away, but just weird it flashed up and shut off the auto stop/start system in the V6.

TIA

Checkyour rear door ajar sensor make sure its plugged in

 

There are so many posts lacking that 'I replaced the aux battery, it didn't go away immediately but then after driving it a few days it did!' I am digging around to find. I've heard the latter, but the threads tend to just drop off with no resolution after a couple suggestions and no posted 'this was my fix'.

I'm at the 'replaced my battery but still have the light, sure hope I don't have to take it to the dealer' phase myself.

 

Here's what I had to deal with on a customer car 2019 Dodge Durango that came in with the "service S/S sytem"
Replaced aux battery, perform a 'hard reset' (disconnect negative cable from main battery and from aux battery - if you do the main battery only it will NOT work)
Drove it for about 15 minutes until all the conditions were met for the S/S system.
Soon as it got up to temperature the warning went away.
Good luck!

 

we have a 2019 Chrysler Pacifica. this is a known issue on the Pacifica forums. its usually 1 or more of 3 things.

1) bad Aux battery
2) failing main battery
3) not being driven enough to charge/keep charged the Aux battery.

we haven't had the issue on our 2019 so I haven't had to become an expert on this yet.

all the Pacifica's have SS, but only the V6 Durangos have SS. you might want to browse the Pacifica forums for the most info.

 

#3 is the main culprit with my wife's new jeep. She only puts 50 miles a week on it if that and it mainly sits in the driveway.
Oh man why did I drop 55k on it.. LOL

 

I have replaced our battery, but can’t seem to reset so the light will go off. Please help

 

I had issues that needed the intelligent battery sensor changed. ESS was working only intermittently. The shop ran some tests and determined that it was the sensor. Changed and back on the road.

 

FWIW if the IBS is faulty it will leave a body code "Bxxx" which most off the shelf code readers only pull powertrain codes "Pxxx". Now if you have the software called Alfaobd (~$60) and an obd interface that is compatible with alfa (range from $20 to $140) you can actually read SOC from the IBS.

B2193-00-INTELLIGENT BATTERY SENSOR INTERNAL
Theory of Operation
The Intelligent Battery Sensor (IBS) is an electrical shunt with a microprocessor that is mounted in-line with the negative Battery Cable. The IBS monitors the current flow and voltage. The IBS also has a built in thermistor that calculates the Battery temperature. The microprocessor uses this data to calculate Battery state of charge, Battery internal resistance, charge received, charge delivered, and time in service. This information is reported through a LIN Bus circuit to the Body Control Module (BCM). The BCM broadcasts the information to the Powertrain Control Module (PCM) over the CAN Bus.
When Monitored and Set Conditions
When Monitored:
This diagnostic runs continuously when the following conditions are met:

• The ignition in the Run position for at least five seconds.
• The battery voltage is between 10.0 and 16.0 volts.

Set Conditions:

• The Body Control Module receives a message through the LIN Bus 1 circuit indicating the Intelligent Battery Sensor (IBS) has an internal fault.

Default Actions:

• Functionality related to the Intelligent Battery Sensor (IBS) is not fully operational.

Here is some more info on the IBS if you want to learn more.

OPERATION
The Intelligent Battery Sensor (IBS) contains a low value resistor, or shunt. The shunt creates voltage drop, which is read by an internal microcontroller to determine the current flow in and out of the battery. In addition to the shunt, the IBS contains a sensor to monitor the battery’s temperature. Data gathered by the IBS, including temperature, voltage, and current measurements, are transmitted over a LIN communication bus to either the Body Control Module (BCM) or the Powertrain Control Module (PCM), depending on the application. The IBS serves two primary purposes. The first is to provide the Powertrain Control Module (or PCM) with both immediate and historical battery information, so the PCM can precisely control the charging system. Precise charging is important on a vehicle equipped with an Absorbent Glass Material (or AGM) battery, because they are especially sensitive to overcharging. The second purpose is to provide data to the BCM for operation of the load-shedding feature. A fused power circuit and the LIN bus are connected to the IBS though a two-terminal connector.

In addition to real-time measurements, the IBS transmits some calculated battery data over the LIN bus, including state of charge, state of health, and state of function. These values are calculated by storing measurements over time.

The battery sensor is readable/diagnosable via a “scan tool” that can display all of the available parameters needed for vehicle servicing or trouble shooting.

Information the Intelligent Battery Sensor (IBS) send out on the CAN Bus is

• SOC = Battery state of charge (or SOC) is expressed as a percentage. The IBS calculates the SOC based on measured voltage, and charge and discharge rates. Therefore, SOC is not a direct percentage of battery voltage.
• SOF = Battery State of Function: Battery state of function (or SOF) is a calculated prediction of the lowest voltage the battery will drop to during engine cranking.

The PCM and BCM use this calculated information to optimize vehicle power management for increased fuel efficiency. The data transmitted from IBS is interpreted and sent over the CAN network by the module connected the IBS’s LIN bus.

When the IBS is powered up for the first time or is powered after a power disconnection, it enters a “recalibration” phase, where the IBS must recognize the type of battery and its characteristics and state. So in this phase the tolerances on the state functions (SOC, SOF) are greater than in normal working condition. When IBS is disconnected from the battery, the device loses its stored memory. When power is restored, the IBS starts a relearn process. Until the relearn process is complete, accurate battery state information is unavailable to other vehicle systems. The IBS relearn process requires three to five normal, operator initiated starts with at least eight hours of engine off time between each start. Usually, the process takes a few days of vehicle operation to complete. Remember, the relearn process is restarted every time power is reconnected to the IBS. This has a major effect on the stop/start feature.

A Note about Stop/Start and the IBS - Stop/start operation places a heavy demand on the battery. So, during stop/start operation, the PCM boosts the charging system’s output to immediately recharge the battery after a start. For example, on the Ram HFE, charging output is boosted to 220 amps. This very high charging rate would not be prudent without knowing detailed battery information, because the battery or charging system could be damaged. Also, the PCM does not have enough data to determine if the battery has enough power to restart the engine. So, stop/start is disabled during the IBS relearn mode. The EVIC displays various messages when the stop/start feature is disabled.

If the IBS is faulty it cannot be serviced, it must be replaced.

 

Open rear door their is a small panel on back door under window take panel off and make sure everything is plugged in

 

Everyone tells me to check the fuse block under the hood underneath the jump start post…there’s a main aux battery fuse there that is prone to going bad.

 

Yes, there is a 5 amp fuse that should also be checked. BTW beware that the FSM labels the aux posts incorrectly.

2017 Durango GT won’t start!

I was sitting at a stop light, and my Durango cut off with absolutely no warning. I finally got it to crank and got it home. The next day it won’t crank at all. The cab lights and dash lights come on, but when I push my start button, it just clicks and won’t turn over. We tried to jump it off...

Just happened to me it comes on and then it goes off the truck right horrible when the light is on

 

Check for codes, usually if stop-start is not available it will state why...like "battery saver", "steering angle", "climate"...etc , but if it just states unavailable it might be due to other problems which could manifest into a pending or stored code.

 

Yes it's under the seat. Remove the rear floor mat and then slide the front seat all the way forward. There is a plastic panel to pull up between the seat rails that exposes the batteries.

Hey meStevo, I got same issue I connected obd2 reader got DTC code:
P0027 which calls out the exhaust variable valve timing solenoid bank1. So I erased the code and ss message and test drove about 20 + miles got home and parked. Next day car wouldn't start. Battery v was 12.4.
Towed it to AAA Mech couldn't pinpoint
Problem but stated that the exhaust VVT solenoid was good and ended up finding a bad starter $1300 latter I picked up my baby and it Stop running in middle of intersection, now mech says I need a new Transmission Control Module @ $2800 + labor.
Lucky me Mopar on strike and no part availability for 6months. I was able to drive durango home while I turned off A ss by pressing button on console.
Car ran normal up to 45 mph. I wonder if I can just drive it without using the A ss feature till I can get it fixed.

 

What I can say is you should get your money back from that mechanic and be very doubtful of their diagnosis of the TCM. None of that adds up at all.
