TSB 23-010-20 REV. A a.k.a. (RRT) 20-020

Description:
SUBJECT: Sunroof Water Leak
OVERVIEW: This bulletin involves testing the sunroof for leaks and replacing the power sunroof glass, if necessary

Models:
2019 (DS) RAM 1500 Pick
2019 (DJ) RAM 2500 Pick
2019 (D2) RAM 3500 Pick
2019 (DX) RAM Truck (Mexico)

Link to TSB: https://static.nhtsa.gov/odi/tsbs/2020/MC-10175564-9999.pdf

Notes: My dealership performed the syringe test in the TSB and determined my vehicle needs the repair.
 
TSB 08-012-20

mod: (Superseding TSB 08-149-21) Updates DASM to 56029827AH

Description:
The customer may describe one or more of the following:
  • Brakes may intermittently apply unexpectedly together with Instrument Panel Cluster (IPC) warnings.
  • IPC warnings for the Forward Collision Warning (FCW) informing the driver to apply the brakes.

Models:
2019 (D2) RAM 3500 Pickup
2019 (DD) RAM 3500 Cab Chassis
2019 (DF) RAM 3500 <10K Cab Chassis
2019 (DJ) RAM 2500 Pickup
2019 (DP) RAM 4500/5500 Cab Chassis

Link to TSB.
Alternate link to TSB.

Notes:
This updates the DASM module to version 56029827AG.

I have driven my truck 23,000 miles, and only twice has the truck unexpectedly applied the brakes and displayed the FCW. It happened when there was absolutely nothing in front of the truck for miles, so I thought it was a bug or a bird that tripped the sensor, but apparently this is a sporadic software glitch.

SUBJECT:
P203E and P203F Additional Diagnostic Information

OVERVIEW:
This bulletin provides additional information regarding diagnosing Diesel Exhaust Fluid (DEF) issue
in extreme cold weather. Diagnostic Trouble Codes (DTCs) P203E - Reductant Level Sensor 1
Circuit Intermittent and/or P203F - Reductant Level Too Low set.

MODELS:
2019 - 2021 (DJ) RAM 2500 Pickup
2019 - 2021 (D2) RAM 3500 Pickup
2019 - 2021 (DD) RAM 3500 Cab Chassis
2019 - 2021 (DP) RAM 4500/5500 Cab Chassis

NOTE: This bulletin applies to vehicles within the following markets/countries: North
America, LATAM, EMEA and APAC.

NOTE: This bulletin applies to vehicles equipped with a 6.7L I6 Cummins Turbo Diesel
Engine (Sales Code ETL or ETN) or 6.7L I6 Cummins HO Turbo Diesel Engine (Sales Code ETM).

DISCUSSION:
Several reports have been received of vehicles in the field setting DTCs P203E and/or P203F.
Many of these vehicles were located in areas of extreme cold, or in areas where the temperatures
can go from extreme cold to warm in short periods of time. An analysis of returned parts from
several of these vehicles has shown a high rate of No Trouble Found (NTF). Further analysis of
information returned from the field, has narrowed down the cause into 3 possible scenarios.
• Scenario #1 - DEF Tank Overfilled.
• Scenario #2 - Residual Ice in the DEF Tank or Covering the Level Sensor.
• Scenario #3 - DEF Crystallization Covering the Level Sensor.
NOTE: If you encounter a vehicle with the above condition, please review each scenario
below, and repair accordingly prior to replacing any parts.
DEF Level Sensor Operation:
The DEF level sensor is new starting in the 2019 Model Year. The new design level sensor uses an
Ultrasonic Frequency (UF) signal to detect the proper fluid level. Previous model years use a radio
frequency type sensor which operates differently, and can be less accurate.
In order for the UF level sensor to operate properly, it is crucial that there is sufficient air space
between the top level of the fluid, and the top of the DEF tank. DEF tanks are specially designed to
have an air space above the fluid, which is crucial for the level sensor to function. Without that air
space, the UF signal cannot be returned to the sensor properly leading to a “No Echo” condition.

Previously STAR case #S2019000002 Hands On Steering Wheel Message In EVIC

Previously posted as TSB-012-20 for 2019 vehicles https://hdrams.com/forum/index.php?threads/tsbs.3028/post-67116


Case Number: S2019000002
Release Date: 04/17/2020
Symptom/Vehicle Issue: Hands On Steering Wheel Message In EVIC

Discussion: On vehicles equipped with Lane Departure Warning (LDW), a driver may experience a message on the cluster display instructing them to "Place hands on steering wheel" when their hands are already on the steering wheel and LDW is on.

This can occur and doesn't indicate an issue with the vehicle or any ECU.

Hands on steering wheel detection sensing is done by monitoring driver torque on steering wheel over a period of time. Driving on straight and flat roads does not require much steering torque input from the driver and can trigger a warning to "Place hands on the steering wheel". During this warning if a small steering wheel movements is detected the message will no longer display.

  • 9-13-21 truck in for various repairs. issue noted.
  • 9-16-2021: Dealer called to say there's a flash available. I will update the TSB post when I know more.
  • 9-17-2021: Received vehicle back with labor Op code 18-20-09-94 - Flash DASM with latest code (found in TSB 18-012-20)

I wasn't able to find the specific TSB, not do I have the DASM firmware code level, but it appears this TSB was upated or rolled up into a large TSB for park sense, FCW braking, lane sense issues, etc.
