Turn Signal Switch

Replace the multifunction turn signal stalk switch on a 2024 Tesla Cybertruck Cyberbeast. Note that the Cybertruck uses steer-by-wire — the steering column contains no mechanical shaft to the wheels, but the column still houses the stalk assembly and clockspring/SCCM electronics that must be handled carefully.

Parts

• Turn signal / multifunction stalk switch assembly (Cybertruck-specific) × 1 — Tesla Cybertruck OEM stalk switch — verify part number against VIN at time of order

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the low-voltage battery. NOTE: This Cybertruck uses a 48V architecture — locate the 48V low-voltage battery per the manufacturer-specified location and disconnect the negative terminal first using insulated tools.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage (800V on Cybertruck) and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Wait an additional 2 minutes after low-voltage disconnect before working near the airbag/clockspring area to allow SRS capacitors to discharge.
7. Center the front wheels (visually) before disconnecting — although steer-by-wire decouples the yoke, the road-wheel actuator should remain in its last commanded position. Do not turn the yoke after power-down.
8. Cover the driver's seat, sill, and lower A-pillar with clean soft covers to protect interior and stainless trim.

Procedure

1. 1

   Remove the yoke (steering wheel)
   Tilt and telescope the column to its fullest accessible position (do this BEFORE low-voltage disconnect if possible; otherwise it will be in last-saved position). With low-voltage already disconnected, locate the yoke retention fasteners behind the yoke per the manufacturer-specified procedure. Disconnect the yoke control harness and the airbag (yellow) connector by lifting the lock tab and gently pulling. Remove the yoke straight off the hub. Set yoke face-up on a padded surface — never face-down (airbag deployment direction).
   ⚠️Yellow connector = airbag. Do not pull on the wire. Lift the CPA lock first, then release the main lock.
2. 2

   Remove lower and upper steering column shrouds
   Locate and remove the cover screws securing the lower column shroud. Separate the lower shroud from the upper shroud at the seam using a plastic trim tool. Remove the upper shroud. On Cybertruck, the shrouds may also have integrated clips around the instrument cluster bezel — release these gently to avoid scratching the cluster surround.
   ⚠Do not pry against the stainless dash structure with a metal tool — use plastic only.

   Cover Screws11 Nm (8 lb-ft)
3. 3

   Identify the stalk switch on the SCCM
   With shrouds removed, identify the multifunction stalk assembly mounted to the Steering Column Control Module (SCCM). On Cybertruck this stalk handles turn signals, wiper/washer, and gear selection backup functions — confirm you are working on the correct stalk before removing fasteners.
   ℹ️Cybertruck uses screen-based primary gear selection; the stalk is a redundant input. Removing it does not free the column from the dash.
4. 4

   Disconnect the stalk electrical connector
   Locate the stalk's electrical connector at the SCCM/clockspring interface. Release the lock tab and disconnect. Inspect the connector and pins for corrosion or bent terminals before continuing.
5. 5

   Remove the stalk switch from the column
   Remove the switch mounting screws securing the stalk to the SCCM housing. Support the stalk as the last screw is removed and withdraw it from the housing. Note the orientation of any locating tabs for reinstallation.
   ⚠Do not rotate the clockspring/rotary coupler while the stalk is removed. The road-wheel actuator is fixed; rotating the upper coupler can damage internal ribbon wiring.

   Switch Mounting Screws3 Nm (2 lb-ft)
6. 6

   Compare new and old stalks
   Place the replacement stalk next to the original and verify part number, connector keying, and lever orientation match exactly. Cybertruck stalks are not interchangeable with Model 3/Y/S/X stalks despite visual similarity.
7. 7

   Install the new stalk switch
   Seat the new stalk into the SCCM housing, aligning locating tabs. Hand-start all switch mounting screws before final tightening to avoid cross-threading the plastic housing. Torque to specification.
   ⚠Over-torquing these screws will strip the plastic SCCM boss — use a calibrated 1/4" torque wrench.

8. 8

   Reconnect the stalk harness
   Reconnect the stalk's electrical connector until the lock tab clicks fully home. Tug-test the connector to confirm engagement.

Reassembly

1. Reinstall the upper and lower steering column shrouds, ensuring all clips are seated before driving screws. Torque cover screws to spec (Steering Column Covers torque).
2. Reinstall the yoke onto the column hub in the same orientation it was removed. Reconnect the airbag (yellow) connector first, then the control/heater harness. Verify CPA locks are fully seated.
3. Torque the yoke retention hardware to OEM specification — refer to Tesla Service Manual.
4. Reconnect the 48V low-voltage battery (positive first if disconnected, then negative last per standard practice — verify against Tesla service documentation for Cybertruck-specific sequence). Torque terminal bolts to spec.
5. If a ground bolt was disturbed during the procedure, torque to the Ground Bolt specification (CRITICAL).
6. Close all doors, wait 30 seconds, then approach with the key fob to wake the vehicle.

Verification

• Power up the vehicle and verify no SRS/airbag warning, no EPAS/steer-by-wire warning, and no stalk-related fault on the center display.
• Test left turn signal, right turn signal, lane-change tap function, high-beam flash, and (if equipped on this stalk) wiper/washer functions.
• If the vehicle displays a steering angle calibration request or a stalk learn request, perform via Service Mode or a short low-speed drive cycle in a safe area as instructed by the on-screen prompt.
• Verify Autopilot/ADAS features arm normally — turn signal input is required for automatic lane change, so test signal recognition by the driver-assist system.
• Inspect column shrouds for even gaps and that no clips were broken during reinstallation.
• Service interval reminder: while the column is open, this is also a convenient time to verify cabin air filter age (Tesla recommends replacement every 2 years) — though it is a separate job.
