Check if your Vehicle has a Recall

 

New Safety Recall Advanced Communication – B2A

FCA US LLC (FCA US) has announced a safety recall on certain 2023 Model Year (DF) Ram 3500 10k Lb. Cab Chassis, 2023 (DS) Ram 1500 Pickup, 2023 and 2024 Model Year (D2) Ram 3500 Pickup, (DD) Ram Cab Chassis, (DJ) Ram 2500 Pickup, (DP) 4500/5500 Cab Chassis vehicles.

 

REASON FOR THIS SAFETY RECALL

Some of the above vehicles may have been built with a steering column control module (“SCCM”) turn signal self-canceling anti-jam component out of specification or an internal short circuit on the SCCM printed circuit board (“PCB”).

The condition described above does not comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 571.108 S9.1.1 requires that “The turn signal operating unit must be self-canceling by steering wheel rotation and capable of cancellation by a manually operated control.” The SCCM in the suspect vehicles may not allow the self-canceling feature to function correctly. FMVSS 571.108 S6.1.5 requires that “…only those light sources intended for meeting lower beam photometrics are energized when the beam selector switch is in the lower beam position, and that only those light sources intended for meeting upper beam photometrics are energized when the beam selector switch is in the upper beam position.” The SCCM in the suspect vehicles may cause the high beams to activate when using the turn signal, or the turn signal to activate when using the high beams.

A turn signal which remains active after a completed turn may cause surrounding drivers to misunderstand the intent to change vehicle direction. High beam activation when the turn signal switch is activated may result in reduced visibility of oncoming drivers. Either of these conditions may cause a vehicle crash without prior warning.

 

SERVICE ACTION

FCA US will conduct a voluntary safety recall to inspect and, if necessary, replace the steering column control module. The remedy for this condition is not currently available. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in 4th Quarter of 2023.

Revision 1
December 2023

SYMPTOM DESCRIPTION

About 142,000 of the above vehicles may have been built with a steering column control module (SCCM) turn signal self-cancelling anti-jam component out of specification, an internal short circuit on the SCCM printed circuit board (PCB), and/or a turn signal lever debouncing time limit which is too short.

The conditions described above do not comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 571.108. FMVSS 571.108 S9.1.1 requires that “The turn signal operating unit must be self-cancelling by steering wheel rotation and capable of cancellation by a manually operated control.” The SCCM in the suspect vehicles may not allow the self-cancelling feature to function correctly. FMVSS 571.108 S6.1.5 requires that “…only those light sources intended for meeting lower beam photometrics are energized when the beam selector switch is in the lower beam position, and that only those light sources intended for meeting upper beam photometrics are energized when the beam selector switch is in the upper beam position.” FMVSS 571.108 S4 defines a Turn signal operating unit as “…an operating unit that is part of a turn signal system by which the operator of a vehicle causes the signal units to function.” The SCCM in the suspect vehicles may lead to an inadvertent turn signal activation. The SCCM in the suspect vehicles may cause the high beams to activate when using the turn signal, or the turn signal to activate when using the high beams.

A turn signal which remains active after a completed turn may cause surrounding drivers to misunderstand the intent to change vehicle direction. High beam activation when the turn signal switch is activated may result in reduced visibility of oncoming drivers. An inadvertent turn signal activation may cause surrounding drivers to misunderstand the intent to change vehicle direction. Any of these conditions may cause a vehicle crash without prior warning.

 

SCOPE

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the

Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

 

WARNING: To avoid serious or fatal injury, use extreme care to prevent any foreign material from entering the Driver AirBag (DAB), or becoming entrapped between the DAB cushion and the DAB trim cover. Failure to observe this warning could result in occupant injuries upon airbag deployment.

 

CAUTION: If the clockspring is not properly centered in relation to the Steering Angle Sensor (SAS), steering wheel, steering shaft and steering gear, it may be damaged or Diagnostic Trouble Codes (DTC) may be set in the SAS. Service replacement clocksprings are shipped pre-centered and with a locking pin installed. This locking pin should not be removed until the clockspring has been installed on the steering column.

 

  1. Place the front wheels in the straight-ahead position.

 

  1. Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.

  1. Position the upper shroud (1) onto the steering column over the lower shroud (3) (Figure 2).

 

  1. Align the snaps features on the upper and lower shroud halves and apply hand pressure to snap together.

 

  1. From below the steering column, install the two outboard screws within the recess areas (2) that secure the upper shroud (1) to the lower shroud (3) (Figure 2).

 

NOTE: Do not reconnect the negative cable to the battery at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component.

 

NOTE: The following procedure should be performed using a diagnostic scan tool to verify proper Supplemental Restraint System (SRS) operation following the service or replacement of any SRS component. Refer to the appropriate diagnostic procedures.

 

  1. During the following test, the negative cable remains disconnected and isolated from the battery, as it was during the Supplemental Restraint System (SRS) component removal and installation procedures.

 

  1. Be certain that the diagnostic scan tool contains the latest version of the proper diagnostic software.

Connect the scan tool to the 16-way Data Link Connector (DLC) (2). The DLC is located on the driver side lower edge of the instrument panel, near the steering column opening cover (1) and outboard of the steering column (Figure 17).

 

  1. Transition the status of the ignition switch (also known as the Keyless Ignition Node/KIN or Ignition Node Module/IGNM) to ON and exit the vehicle with the scan tool.

 

  1. Check to be certain that nobody is in the vehicle, then connect the negative cable to the battery.

 

  1. Using the scan tool, read and record the active (current) Diagnostic Trouble Code (DTC) data.

 

  1. Next, use the scan tool to read and record any stored (historical) DTC data.

 

  1. If any DTC is found in Step 28 or Step 29, refer to the appropriate diagnostic information.

 

  1. Use the scan tool to erase the stored DTC data. If any problems remain, the stored DTC data will not erase. Refer to the appropriate diagnostic information to diagnose any stored DTC that will not erase. If the stored DTC information is successfully erased, go to Step 32.

 

  1. Transition the status of the ignition switch to OFF for about 15 seconds, and then back to ON. Observe the airbag indicator in the instrument cluster. It should light from four to six seconds, and then go out. This indicates that the SRS is functioning normally and that the repairs are complete. If the airbag indicator fails to light, or lights and stays ON, there is still an active SRS fault or malfunction. Refer to the appropriate diagnostic information to diagnose the problem.

 

NOTE: Proper SCCM installation must also be confirmed by viewing the SAS menu item, Data Display function using a diagnostic scan tool.

 

SERVICE PROCEDURE – DP, DJ, DF, DD AND D2

F.  Remove SCCM

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

 

WARNING: To avoid serious or fatal injury, use extreme care to prevent any foreign material from entering the Driver AirBag (DAB), or becoming entrapped between the DAB cushion and the DAB trim cover. Failure to observe this warning could result in occupant injuries upon airbag deployment.

 

CAUTION: If the clockspring is not properly centered in relation to the Steering Angle Sensor (SAS), steering wheel, steering shaft and steering gear, it may be damaged or Diagnostic Trouble Codes (DTC) may be set in the SAS. Service replacement clocksprings are shipped pre-centered and with a locking pin installed. This locking pin should not be removed until the clockspring has been installed on the steering column.

 

  1. Place the front wheels in the straight-ahead position.

 

NOTE: If the vehicle is equipped with an auxiliary battery, when disconnecting and isolating the negative battery cable for the 12-volt system, both batteries will need to be disconnected to power down the vehicle.

 

  1. Disconnect the Intelligent Battery Sensor (IBS) wire harness connector (1) (Figure 18).

 

NOTE: Failure to disconnect the IBS wire harness connector can lead to damage of the IBS wire harness connector.

 

  1. Loosen the ground terminal nut (2) and remove the negative battery cable with IBS from the battery and isolate it.

 

  1. If the vehicle is equipped with an auxiliary battery, Loosen the clamp (1) and remove the clamp from the battery and isolate.

 

NOTE: If the vehicle is equipped with an auxiliary battery, install the negative clamp on the negative battery post and tighten to the proper torque specifications prior to connecting the IBS.

 

  1. Wait 2 minutes for capacitor discharge.

 

  1. Locate the access hole dimples (1) in the lower surface of the steering wheel hub rear trim cover near each of the two horizontal spokes.

 

  1. Using the Remover, Driver Air Bag 2050200100, pierce the trim cover at the dimple and insert it through one of the steering wheel access holes. A guide and notch integral to each side of the steering wheel hub rear trim cover and the mounting/horn switch plate will assist in directing the tool to the ends of the retainer spring (Figure 19).

 

  1. When the tool makes contact with the retainer spring, push inward (toward the steering column) on the tool far enough to disengage the retainer spring from under the hook of the steering wheel armature.

 

  1. Pull the released side of the DAB away from the steering wheel far enough to insert a trim stick or another long and thin obstacle between the released spoke of the DAB trim cover and the steering wheel spoke hub cavity. This will help to prevent the released end of the retainer spring from becoming accidentally engaged again while the opposite end of the retainer spring is being released.

Chronology :

  • On May 4, 2023, the FCA US LLC (“FCA US”) Technical Safety and Regulatory Compliance (“TSRC”) organization was notified of a potential issue related to malfunctioning SCCMs on some 2023-2024 MY Ram Heavy Duty and Ram 1500 Classic vehicles.
  • From May 2023, through October 2023, FCA US TSRC conducted an analysis of SCCM failure patterns and vehicle history and determined that the affected vehicles may have been built with SCCMs which may not function as intended.
  • On October 18, 2023, the FCA US TSRC organization recognized a vehicle build issue existed on certain vehicles related to a condition that can lead to failure of turn signal self-canceling or turn signal activation when high beam requested or vice versa, potentially resulting in a noncompliance with FMVSS No. 108.
  • On November 21, 2023, FCA US determined, through the Vehicle Regulations Committee, to conduct a voluntary safety recall of the affected vehicles relating to the SCCM turn signal self-canceling anti-jam component out of specification and the internal short circuit on the SCCM PCB.
  • From October 18, 2023, through November 2023, FCA US TSRC conducted further analysis of SCCM failure patterns and vehicle history and determined that the affected vehicles may have been built with SCCMs with an additional condition which may cause the SCCM to not function as intended.
  • On December 7, 2023, FCA US determined, through the Vehicle Regulations Committee, to expand this recall to include the turn signal lever debouncing time limit which is too short issue.
