TSB software updates. . .

I recently took my '15 Ram QC, 3.6L to the dealer for a state inspection & tire rotation. While there, they updated the vehicle software with the following (according to the service order):

--Flashed PCM for TSB 18-103-16
--Flashed TCM for TSB 21-075-15
--Flashed RFH for TSB 08-044-16

I Googled the crap out of these and found nothing except general info. Any idea what these TSBs do or change? Everything seems to work the same, although the shifting may be a little smoother, if that's possible.

You might have to go back to them and ask them to explain it to you.

Every time they do an update on my truck they give me a print out exactly what was done and what it does to the truck.

I got a print-out, with the TSB numbers, but no details. The service writer did mention that one of them was for the RF hub and pertained to the ignition switch. He didn't comment on the other two. I didn't ask for more details because I thought I'd be able to find it online. Thanks for the reply!

AllData dot com would have the info in detail but I think you need a paid subscription to see it.

Kori (Ramcares) responded to me this afternoon with the following info--excellent customer communication. . .we're lucky to have her on our forums!:

Hey Rob,

The first TSB deals with the following for a PCM flash:

SYMPTOM/CONDITION:
Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further
investigation the technician may find one or more of the following Diagnostic Trouble
Codes (DTCs) have been set:
· U1424-00 - Implausible Engine Torque Signal Received (14 and 15 MY).
· P2299 - Brake Pedal Position / Accelerator Pedal Position Incompatible (14 and 15
MY).
· P0116 - Engine Coolant Temperature Sensor Performance (14 and 15 MY).
· P0335 - Crankshaft Position Sensor Circuit (14 and 15 MY).
· P1239 - Engine Oil Temperature Too Low (15 MY Sales Code ERB).
· P0300 - Multiple Cylinder Misfire.
· P0456 - EVAP System Small Leak.
· P0607 - ECU Internal Performance.
· P2096 - Downstream Fuel Trim System 1 Lean.
NUMBER: 18-103-16 REV. C
GROUP: Vehicle Performance
DATE: December 20, 2016
· P2097 - Downstream Fuel Trim System 1 Rich.
· P2098 - Downstream Fuel Trim System 2 Lean.
· P2099 - Downstream Fuel Trim System 2 Rich.
· P1004 - Short Runner Valve Control Performance.
· P2008 - Short Runner Valve (SRV) Control Circuit.
· P2016 - Intake Manifold Runner Position Sensor Circuit Low.
· P2017 - Intake Manifold Runner Position Sensor Circuit High.
· P26AB - Engine Coolant Bypass Valve Stuck.
· U0140 - Lost Communication With Body Control Module (attempting to clear this
DTC will be unsuccessful) (4.7L or 3.6L).
· P0607 - ECU Internal Performance (with 4.7L).
The following improvements are also included in this update:
· **Improved driveability and customer satisfaction while DTC U1424 Is Active (14 MY
with 3.6L or 5.7L Only).**
· Throttle Position Sensor (TPS) calibration (14 and 15 MY).
· Corrects a false oil pressure lamp illumination at key on (14 and 15 MY with 5.7L).
· Shift quality of the first shift after a few hours of vehicle drivetrain cooling down.
· Automatic Shut Down (ASD) relay enhancements to improve fuel pump relay
initialization at key on - (Auto Shutdown).
· Charging system voltage regulator control improvements.
· System improvements to prevent MIL illumination with a DTC P0300 - Multiple
Cylinder Misfire when using a block heater in ambient temperatures greater than
-29°C (-20°F).
· Enhanced Automatic Oil Change Indicator (EAOCI) system improvements to switch
to a severe duty cycle algorithm anytime the PCM is replaced to ensure the
customer receives a timely oil change required message.
· Scan tool improved accuracy on mode 6, cylinder imbalance.
· The cruise control system intermittently turns off when pressing the accelerate
button repeatedly (with 5.7L).
· A less than desired idle speed after performing a hard braking maneuver.

The second TSB deals with the transmission heater assembly reinforcement plate, and replacing it if the following is detected:

SYMPTOM/CONDITION:
A small number of customers may notice the presence of transmission fluid in the engine
coolant.

The third TSB is to reprogram the Radio Frequency Hub Module (RFHM) software:

SYMPTOM/CONDITION:
Customers may describe the instrument cluster is illuminating by itself after the ignition has
been off for an extended period of time (10 minutes or more).

Well aware this thread has been dead for years but curious if anyone knows what software level this TSB brings the PCM/TCM up to?

Thanks in advance
