Front Impact Sensor may Disconnect in a Crash

If the ORC module does not receive a signal from the front impact sensor, both frontal air bags and the seat belt pretensioners will not deploy in the event of a crash, increasing the risk of injury.

 

Summary

Chrysler (FCA US LLC) is recalling certain model year 2016-2017 Jeep Wrangler vehicles manufactured June 16, 2015, to August 14, 2016.

In certain crash conditions, the front impact sensor wiring may be pulled until it detaches before a signal can be received by the Occupant Restraint Controller (ORC).

 

Remedy

Chrysler will notify owners, and dealers will reroute the front impact sensor wiring and relocate the impact sensor branch, free of charge.

The recall began on November 10, 2016.

Owners may contact Chrysler customer service at 1-800-853-1403.

Chrysler’s number for this recall is S76.

Safety Recall S76 / NHTSA 16V-734 Front Impact Sensor Wires

 

NOTE: Revised dimension in Steps 40 and 44.

 

Models

2016-2017 (JK) Jeep Wrangler

 

NOTE:  This recall applies only to the above vehicles built from June 14, 2015 through August 13, 2016 (MDH 061411 through 081303).

 

IMPORTANT:  Some of the involved vehicles may be in dealer new vehicle inventory.  Federal law requires you to complete this recall service on these vehicles before retail delivery.  Dealers should also consider this requirement toapply to used vehicle inventory and should perform this recall on vehicles in forservice.  Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The front impact sensor wire(s) on about 182,000 of the above vehicles may become detached during a crash event before the “impact signal” is recorded by the Occupant Restraint Controller (ORC).

NOTE: For 2017 MY vehicles equipped with LED Headlamps (20 vehicles were identified within the population) replacement of both Headlamp Units is required. Do not order Headlamps until inspection and verification has been completed. 

Each dealer with vehicle(s) equipped with LED headlamps will need to email the VIN requiring parts to campaignteam@fcagroup.com due to the small vehicle population.  Once the VIN is verified parts will be ordered on your behalf.  Approximately 20 vehicles are expected to require 68304050AA and 68304051AA.

 

68304050AA        Headlamp Unit, Right (LED) (2017 my ONLY)

68304051AA        Headlamp Unit, Left (LED) (2017 my ONLY)

 

  1. Position the right headlamp unit close enough to the front of the vehicle to connect the engine compartment wire harness connector to the headlamp bulb connector receptacle.
  • For 2017 MY vehicles equipped with LED headlamp units, align the NEW right side LED headlamp unit to the three mounting studs and press the headlamp unit until all three positions are snapped in securely. Repeat on the left side. Continue with Step 58.
  • For vehicles equipped without LED headlamp units, continue with step 54.
  1. Position the headlamp unit by aligning and engaging the index tabs on the back of the lamp with the depressions in the mounting collar on the face of the front end module carrier.
  1. Install the retainer over the headlamp unit and against the mounting collar with the retainer screw tabs in alignment with the screw holes in the collar.
  1. Install and tighten the four screws that secure the retainer to the collar. Tighten the screws until they are fully seated (Figure 2).
  1. Repeat steps 53 through 56 to install the left headlamp unit.
  1. Connect the electrical connectors to the grille (Figure 1).
  1. Position the grille onto the front end module and seat the clips fully (Figure 1).
  1. Install the six push pin fasteners (Figure 1).
  1. Do not connect the battery negative cable at this time. The supplemental restraint system verification test procedure should be performed following service of any supplemental restraint system component. Continue with Section B. Supplemental Restraint System (SRS) Verification Test.

 

B.  Supplemental Restraint System (SRS) Verification Test 

NOTE: During the following test, the battery negative cable must remain disconnected and isolated during steps 1 and 2 of the Supplemental Restraint System (SRS) Verification Test. 

NOTE: The wiTECH scan tool must be used to perform the SRS Verification Test.  The wiTECH software is required to be at the latest release before performing the SRS Verification Test.

  1. Connect the micro pod II to the vehicle data link connector located under the instrument panel to the left of the steering column.
  1. Turn the ignition switch to the “ON” position then exit the vehicle and close the doors.
  1. Check to be certain that nobody is in the vehicle. Connect the negative cable terminal to the vehicle battery negative post and tighten the terminal securely.  If equipped with an Intelligent Battery Sensor (IBS), connect the IBS connector after connecting the battery negative cable terminal to the battery.
  1. Open the wiTECH Diagnostic application.
  1. Starting at the “Select Tool” screen, select the row/tool for the micro pod II device you are using, then select “Next”.
  1. Enter your “User id” and “Password”, then select “Finish”.
  1. Using wiTECH, clear all DTC’s in all modules.

NOTE: Any active Diagnostic Trouble Codes (DTCs) may require an additional key cycle from “ON” to “OFF” to change DTC status from “active” to “stored”.

  1. Turn the ignition switch to the “OFF” position for about 15 seconds, and then back to the “ON” position. Observe the airbag indicator in the instrument cluster.
  • The airbag indicator in the instrument cluster should illuminate for six to eight seconds, and then turn off. This indicates that the SRS is functioning normally and that the repairs are complete. Turn the ignition to the “OFF” position then remove the micro pod II.
  • If the airbag indicator fails to illuminate or the indicator lamp stays ON, there is still an active SRS fault or malfunction. Refer to the appropriate diagnostic information to diagnose the problem.
  1. Close the hood and remove the wiTECH micro pod II.
  1. Return the vehicle to the customer.

FRONT IMPACT SENSOR WIRES


IMPORTANT SAFETY RECALL
S76 / NHTSA 16V-734

 

This notice applies to your vehicle (VIN: xxxxxxxxxxxxxxxxx).

This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.

Dear: (Name)

FCA has decided that a defect, which relates to motor vehicle safety, exists in certain 2016 and 2017 model year Jeep Wrangler vehicles.

The problem is… The front impact sensor wire(s) on your vehicle may become detached during a crash event before the “impact signal” is recorded by the Occupant Restraint Controller (ORC).  Vehicles may experience no airbag or pretensioner deployment in certain crash events where airbag or pretensioner deployment is expected.  Failure to deploy the airbags or pretensioners when required during a crash event could increase the risk of injury or death to front seat occupants.
What your dealer will do…   FCA will repair your vehicle free of charge.  To do this, your dealer will modify the existing wire harness then route and secure the wire harness to a new location.  The work will take about 2 hours to complete.  However, additional time may be necessary depending on service schedules.
What you must do to ensure your safety… Simply contact your Chrysler, Jeep, Dodge or RAM dealer right away to schedule a service appointment.  Ask the dealer to hold the parts for your vehicle or to order them before your appointment.  Please bring this letter with you to your dealer.
If you need help…

 

 

If you have questions or concerns which your dealer is unable to resolve, please contact the FCA Group Recall Assistance Center at either fcarecalls.com or 1-800-853-1403.

  1. Thanks for posting this. I have been looking for this since I received my recall notice. It would be very inconvenient for me to get this performed at a FCA dealer because I do not live close to one and when I called a couple of them they wanted to have the vehicle all day and wanted to sell me services I did not need. I would have to sit in the waiting room all day. With this I can easily perform the work myself in less time and probably do a better job. Without this it would probably never get performed on my vehicle. In my past experience it takes me less time to perform the work myself than to unF*#k what a Chrysler dealer did. The only thing I can’t do is the SRS verification test because I don’t have that scan tool, but I will just be careful and not damage anything.
