TESLA: Model S (2021+)

INTRODUCTION

The Tesla Model S (2021+) is equipped with an event data recorder (EDR). The EDR records data related to vehicle dynamics and safety systems when the system senses a crash or a crash-like situation, such as hitting a road obstacle. This data is stored in the vehicle's Restraints Control Module (RCM).

This guide describes how to retrieve EDR data from the RCM of a Tesla Model S (2021+).

This guide and other Tesla EDR information can be found at https://edr.tesla.com  .

There are two methods for connecting to the RCM:

  1. In-vehicle connection, which allows you to connect to the RCM without removing it from the vehicle. An in-vehicle connection may not be possible if the vehicle has extensive damage. If an in-vehicle connection can be established, data is retrieved with less vehicle disassembly than when using a direct-to-module connection. For more information about in-vehicle retrieval, refer to "Establish an In-Vehicle Connection," below.
  2. Direct-to-module connection, which requires that you physically remove the RCM from the vehicle, then connect to it and retrieve the data. Refer to the "Direct-to-module connection" section of Table 1. EDR Data Retrieval Cable requirements for more information about the required cable. For more information about direct-to-module retrieval, refer to "Establish a Direct-to-Module Connection," below.

TOOLS REQUIRED

To retrieve the data from the RCM, you will need the following special tools:

TABLE 1. EDR DATA RETRIEVAL CABLE REQUIREMENTS

ESTABLISH AN IN-VEHICLE CONNECTION

  1. Release the phone dock.
    NOTE: Release 4x clips and 2x datums, then pull up at the bottom and swing the phone dock out from under the instrument panel.
    G16188254
    G16188255
  2. Remove the phone dock connectors (1x clip and 3x connectors).

USING EXTERNAL POWER FOR THE RCM

Externally powering the RCM refers to applying power to the RCM via the vehicle's "first responder's loop," located in the front trunk. This procedure can be used if a key-fob is not available, 12V DC power is not available to the vehicle system, or the vehicle is otherwise unable to turn on.

NOTE: This procedure requires an external source of 12V power.
WARNING: Follow all manufacturer's instructions for safe use of the external 12V power source.
  1. Open the front hood by using one of the following methods:
    • The touchscreen: touch Controls > Front Trunk  .
      G16188298
    • The key fob: double click the front trunk button on the key fob.
      G16188299
  2. Remove the first responder loop access panel by pulling its rear edge upward to release the five clips that hold it in place. Maneuver the access panel toward the windshield to remove it from the vehicle.
    G16188300
    G16188301
  3. Disconnect the first responder loop harness.
    G16188302
    WARNING: Wait at least 2 minutes for all electrical circuits to fully discharge.
  4. Connect the negative terminal of the external 12V power source to the vehicle chassis.
  5. Connect the positive terminal of the 12V source to pin 3 of the first responder harness.
    G16188303
  6. Proceed to the "Retrieve Data" section of this document to complete data retrieval.

RETRIEVE DATA

  1. Open the Tesla EDR Retrieval Program. The program automatically attempts to connect to the RCM.
    • When connected properly, a green circle and the message "Connected to RCM" displays on the bottom left corner of the window (see Figure 51. EDR program successful connection).
      G16188304
    • If the Tesla EDR Retrieval Program is not communicating with the PCAN-USB adapter, a message displays "Not Connected to PCAN."

      Check the connection to the PCAN-USB adapter.

    • If the Tesla EDR Retrieval Program is communicating with the PCAN-USB adapter, but is not communicating with the RCM, a message displays "Not Connected to RCM."

      Check the connection to the vehicle harness and the vehicle power. If a successful connection through the vehicle communication system cannot be achieved, connect to the RCM using the procedure described in "Establish a Direct-to-Module Connection" on page 6.

  2. Once connected to the EDR, click "Run EDR Retrieval" and follow the on-screen prompts to retrieve and save EDR data.
