Let’s get straight to it—this isn’t just a “cable” behind your Chery
Tiggo 7 Pro’s steering wheel. It’s the
critical “signal bridge” for steering-wheel-mounted safety & control systems: a precision component with a spiral-wound cable (
clock spring) enclosed in a durable plastic housing. Mounted between the steering wheel and the steering column, it enables continuous electrical connection between rotating parts (steering wheel) and fixed parts (vehicle body). Think of it as a “rotating wire connector”—it lets the steering wheel turn freely (up to 3–4 full rotations) while keeping power and signals flowing to the airbag, horn, and steering-wheel multimedia buttons. Without it, the airbag won’t deploy in an accident, the horn won’t work, and steering-wheel controls will fail—directly endangering safety and usability.
This clock spring (airbag coil cable) is
exclusively tailored for Chery Tiggo 7 Pro—always confirm your vehicle’s VIN to ensure a perfect match! It’s calibrated to the Tiggo 7 Pro’s steering system specs: its spiral length and rotation range match the steering wheel’s turning angle (no cable breakage), its connector pins align with the airbag and steering controls (seamless signal transmission), and its housing fits the steering column’s mounting slot (stable installation). Opt for generic parts? You’ll face issues: mismatched rotation range (cable snap), poor signal contact (intermittent horn/controls), or airbag system malfunction (safety risk).
As a dual-purpose component for safety and convenience, it undertakes three vital roles for your Tiggo 7 Pro:
Transmit airbag deployment signals: This is its most critical job. It sends electrical signals between the vehicle’s airbag control unit (ECU) and the steering-wheel airbag. In a collision, it ensures the ECU’s deployment command reaches the airbag instantly—this split-second connection is life-saving.
Power steering-wheel controls: It supplies power and transmits signals to steering-wheel-mounted functions, like the horn, audio volume buttons, cruise control, and instrument-panel display controls. Without it, these controls would stop working as soon as the steering wheel turns.
Accommodate steering wheel rotation: Its spiral-wound “clock spring” design stretches and contracts as the steering wheel turns left or right (up to ~1200 degrees total rotation). This prevents cable tangling or breakage, keeping connections stable no matter the steering angle.

This J433774150 clock spring only works for Chery Tiggo 7 Pro—wrong fit = safety system failure:
Replacing the clock spring involves airbag system disarmament and precise alignment—DIY is extremely dangerous (risk of accidental airbag deployment or system failure):
Safety prep: Techs disconnect the vehicle battery and wait 10–15 minutes (to discharge the airbag capacitor). They then remove the steering-wheel trim to access the old clock spring.
Remove old part: They disconnect the steering-wheel and body-side connectors, unbolt the old clock spring from the steering column, and note the alignment marks (to ensure the new part is centered).
Install new clock spring: They align J433774150 with the steering column’s neutral marks, bolt it securely, and reconnect both sets of connectors.
System reset & test: Critical step—techs reconnect the battery, use professional tools to reset the airbag ECU, and test functions:
Check if the horn works at all steering angles.
Verify steering-wheel controls (audio, cruise) function normally.
Scan for airbag system fault codes to ensure no errors.
Avoid forced steering rotation: Don’t turn the steering wheel fully left/right and hold it for long (strains the spiral cable, leading to early wear).
Inspect for warning signs: If the airbag warning light comes on, the horn works intermittently, or steering controls fail, have the clock spring checked immediately—these are classic signs of damage.
Handle with care during repairs: When removing the steering wheel (e.g., for maintenance), never rotate the clock spring independently—keep it centered to avoid cable tangling.
No aftermarket modifications: Don’t cut or splice the clock spring’s cables. Any modification breaks the airbag system’s safety integrity.

This is an exclusive critical component for Chery Tiggo 7 Pro (confirm VIN for fitment). It consists of a spiral cable and durable plastic housing, mounted between the steering wheel and column, serving as a "signal bridge" for rotating and fixed parts.
Its core functions: Transmit airbag deployment signals (life-saving in collisions), power steering-wheel controls (horn, audio, cruise), and accommodate 3-4 full steering rotations without cable tangling.
It only fits Tiggo 7 Pro, incompatible with other Chery models (e.g., Tiggo 7, 8 Pro) or non-Chery vehicles. Installation requires certified techs (airbag disarmament & calibration); maintenance needs avoiding over-rotation and checking airbag warning lights promptly. Original parts are essential—aftermarket ones risk airbag failure or signal instability.
