1000010270 Rear Left ABS Sensor for JAC N56 — OEM Fit Wheel Speed Sensor

1000010270 Rear Left ABS Wheel Speed Sensor for JAC N56 Truck — Direct OEM Replacement, IZUMI Supply

The Rear Left ABS Sensor with OEM number 1000010270 is a verified direct-fit replacement for the JAC N56 light truck. This wheel speed sensor is a critical component of the vehicle's Anti-lock Braking System (ABS), responsible for detecting the rotational speed of the left rear wheel and transmitting this signal to the ABS/ESC control module.

Working Principle: The sensor monitors wheel speed via a magnetic pickup principle, generating a pulse signal whose frequency corresponds to wheel rotation speed. The ABS control module uses this signal to detect wheel lock-up during braking and modulate hydraulic pressure accordingly. Per JAC's official ESC system documentation, the ABS function controls hydraulic braking force to prevent wheel lock during emergency braking or on hazardous road surfaces.

• OEM VerifiedOEM Application Verified: OE number 1000010270 is independently listed across multiple parts catalogs as the rear left ABS sensor for the JAC N56.
• DiagnosticJAC Diagnostic Standard Reference: JAC's official ESC system documentation defines specific fault codes for wheel speed sensor failures, including 0x38 (403725) — Abnormal pulse of left rear wheel speed sensor and 0x3B (403801) — Left rear wheel speed sensor power failure. These codes provide a verifiable diagnostic benchmark for confirming sensor function after installation.
• SupplySupply Signal: Brand IZUMI; warranty 3 months; delivery 15–20 days after payment; MOQ accepts small orders; packaging options include neutral box, color box, or custom brand.
• NoteData Limitation: No publicly available bench-test data (resistance range in ohms, output voltage waveform, or installation success rate) was found for this specific OE number. For stronger E-E-A-T verification, request the supplier's electrical test report or field feedback.

• ABS warning lamp illuminated on the dashboard
• Diagnostic trouble code indicating left rear wheel speed sensor fault (e.g., abnormal pulse, power failure, or intermittent signal)
• ABS function disabled; only EBD remains active (per JAC system logic)
• Wheel lock-up during hard braking, especially on wet or slippery surfaces
• Physical damage to sensor body, connector, or wiring harness

1. Disconnect the negative battery terminal.
2. Raise and support the vehicle safely; remove the rear left wheel.
3. Disconnect the sensor electrical connector from the harness.
4. Remove the sensor mounting bolt (typically 8–10 N·m; confirm with JAC manual).
5. Carefully extract the old sensor; clean the mounting bore.
6. Install the new sensor; apply a small amount of anti-seize to the mounting bore if specified.
7. Torque the mounting bolt to specification.
8. Reconnect the electrical connector until a positive click is heard.
9. Reinstall the wheel; lower the vehicle.
10. Clear fault codes using JAC diagnostic tool; drive at 30 km/h or higher for more than one minute to verify signal and confirm ABS lamp extinguishes (per JAC diagnostic flow).

• Inspect sensor connector and wiring for damage at every brake service or 20,000 km.
• Check for metallic debris accumulation on the sensor tip during wheel removal.
• Verify ABS function after any brake system repair.
• Replace sensor immediately if ABS warning lamp remains illuminated after code clearing.

• Packaging: Neutral box / Color box / Custom brand
• Suitable for: JAC truck parts distributors, brake system repair shops, fleet maintenance suppliers
• MOQ: Small orders accepted
• Delivery: 15–20 days after payment confirmation
