2. Disable 12V battery: remove cover from 12V battery in rear cargo area, disconnect negative terminal, then positive terminal. Secure cables away from terminals.
3. Wait minimum 2 minutes for airbag system capacitors to discharge.
4. Center steering wheel perfectly straight and verify front wheels are pointing straight ahead.
5. Remove driver's side lower knee bolster panel by removing trim screws.

7. Chock rear wheels securely.

Procedure

1. 1

   Remove steering wheel
   Remove airbag module by accessing retaining fasteners from rear of steering wheel (usually T30 Torx screws). Carefully pull airbag module forward and disconnect yellow airbag connector by pressing release tab. Set airbag aside face-up in safe location away from work area. Remove steering wheel retaining nut and mark steering wheel position relative to shaft with tape or marker. Use steering wheel puller if needed to remove wheel from shaft. DO NOT strike steering wheel or shaft.
2. 2

   Remove steering column covers
   Remove upper and lower steering column cover halves by removing retaining screws. On 2023 Bolt EUV, there are typically screws at bottom and sides of lower cover. Carefully separate covers and remove, being careful not to break clips. Set covers aside.

3. 3

   Disconnect clockspring and column electrical connectors
   Locate clockspring assembly at top of column (yellow housing). Press connector release tabs and disconnect all electrical connectors from clockspring. Identify and disconnect turn signal/multifunction switch connectors, ignition switch connector, and any other column-mounted switches. Label each connector with tape for reinstallation reference. Remove clockspring retaining screws if replacing column (clockspring may be part of column assembly).
4. 4

   Disconnect shift interlock cable (if equipped)
   Locate shift interlock cable connection at ignition lock cylinder or column-mounted actuator. Press release tab and disconnect cable end from mechanism. Remove cable routing clip from column bracket. Note routing path for reinstallation.
5. 5

   Remove instrument panel knee bolster reinforcement
   Remove any remaining lower instrument panel reinforcement brackets that obstruct access to column mounting. This may include metal reinforcement bar above pedals. Remove all retaining bolts and carefully lower reinforcement. Support weight to prevent damage to other components.
6. 6

   Mark and disconnect steering shaft coupling
   Working in footwell and/or from under dash, locate steering shaft coupling where column shaft connects to intermediate shaft. Mark relationship of coupling to both shafts with paint pen or scribe marks for proper alignment during reassembly. Remove coupling pinch bolt completely. Do NOT allow steering column or intermediate shaft to rotate from this point forward. Use wire or tape to secure shaft positions.
   ⚠️Coupling bolt is CRITICAL safety fastener. Inspect threads and replace if damaged. Never reuse if torque-to-yield type (check service manual).

7. 7

   Remove steering column mounting fasteners
   Locate steering column mounting bracket bolts at instrument panel support structure. On 2023 Bolt EUV, there are typically four mounting bolts securing column bracket to IP carrier. Support weight of steering column with one hand or have assistant support it. Remove all column mounting bolts while supporting column weight.
   ⚠Column is heavier than it appears. Support full weight before removing final bolt to prevent dropping column and damaging components.

8. 8

   Remove steering column assembly
   With all fasteners removed and column supported, carefully separate steering shaft from intermediate shaft coupling (should slide apart at marked location). Guide column assembly down and out from under instrument panel, carefully routing all disconnected wiring through opening. Watch for any remaining wire harness clips or brackets. Place old column on clean work surface for inspection and parts transfer if needed.
9. 9

   Prepare new steering column
   Inspect new steering column for shipping locks or pins that must be removed before installation (check with parts supplier). Transfer any components from old column if not included with replacement (verify all sensors, switches, and brackets are present on new column). Compare new column to old column to verify correct part. Ensure steering shaft on new column is in centered position and matches rotation position of intermediate shaft in vehicle.
10. 10

    Install steering column assembly
    Carefully guide new column assembly up into position under instrument panel, routing electrical connectors through opening. Align steering shaft with intermediate shaft coupling, matching alignment marks made during removal. Column shaft and intermediate shaft must both be in centered position. Loosely install all column mounting bolts finger-tight but do not fully tighten yet.
11. 11

    Reconnect steering shaft coupling
    With column supported in position and all mounting bolts finger-tight, align coupling over both shaft ends matching previous alignment marks. Verify shafts have not rotated. Install NEW coupling pinch bolt (if torque-to-yield type) and tighten to specification using torque wrench. Verify coupling is fully seated on both shaft ends.
    ⚠️Coupling bolt torque is CRITICAL. Use calibrated torque wrench. Incorrect torque can cause coupling separation and total loss of steering control.

    Torque column mounting bolts
    Torque all steering column mounting bolts to specification in a cross pattern (top-left, bottom-right, top-right, bottom-left) to ensure even clamping. Verify column is properly seated against mounting surface before final torquing. Re-verify coupling bolt torque after column bolts are tightened.
    ⚠Column mounting bolt torque is critical for proper airbag deployment geometry and steering control. Follow specified sequence.

    Reconnect electrical connectors
    Reconnect all electrical connectors to steering column components in reverse order of removal, using labels as reference. Ensure each connector fully seats with audible click. Reconnect clockspring connectors, ignition switch, turn signal/multifunction switch, and any other column switches. Verify no connectors are missed by comparing to removal documentation.
14. 14

    Reinstall shift interlock cable
    Route shift interlock cable back to column mechanism following original path. Connect cable end to actuator until it clicks into place. Install cable routing clip to column bracket. Verify cable has appropriate slack and is not kinked or binding.
15. 15

    Reinstall steering wheel and covers
    Install steering wheel onto shaft aligning with marks made during removal, ensuring clockspring is still centered. Install steering wheel nut and torque per vehicle specifications (consult service manual for exact value). Reconnect airbag module yellow connector ensuring it locks. Position airbag module on wheel and secure with retaining fasteners (typically 8-10 Nm). Reinstall steering column covers with retaining screws torqued per specification. Reinstall instrument panel reinforcement and knee bolster.

Reassembly

1. Reinstall all instrument panel trim pieces and knee bolster in reverse order of removal.
2. Verify steering wheel is still centered and wheels point straight ahead before reconnecting battery.
3. Reconnect 12V battery: connect positive terminal first, then negative terminal.
4. Before starting vehicle, turn ignition to ON position (do not start) and verify instrument cluster illuminates with no unusual warnings.
5. Perform steering system verification procedure below before operating vehicle.

Verification

• With vehicle stationary and engine off, turn steering wheel lock-to-lock slowly and verify smooth operation with no binding, clicking, or unusual resistance.
• Start vehicle and verify no airbag warning lights remain illuminated after bulb check (light should extinguish within 5-10 seconds).
• Verify all steering column functions operate correctly: turn signals, wipers, cruise control, and any column-mounted switches.
• Verify shift interlock functions correctly: vehicle should not shift out of Park without brake pedal pressed and ignition on.
• Test drive in safe area at low speed, verify steering responds correctly with no play, binding, or unusual noises.
• Perform final steering wheel centering check: on straight, level road at low speed, vehicle should track straight with steering wheel centered.
• If ANY abnormalities are detected, STOP and have vehicle inspected by qualified technician immediately.
• Consider having steering alignment checked by professional after column replacement to verify proper geometry.
