Every pull of the hood release loads a plastic handle that works the Bowden cable against the under-hood latch. When that handle cracks, the cable stops retracting, the latch rests mid-stroke, and the cluster flags Hood Open on a closed hood. The fix is usually a 15-minute handle swap — not a new latch, and not a BCM.

The part is the Hood Latch Release Handle for JAC Refine S3, S2, S5, M4, T6, T8 Pickup Truck, JS2, and JS5. Below: the full fitment matrix, the material upgrade over stock, and the exact symptoms and DTCs a worn handle produces.

Know the Part Before You Buy

JAC Motors (Anhui Jianghuai Automobile Group) cross-sources latch mechanisms from suppliers aligned to ISO/TS 16949. This replacement matches OEM form-factor geometries across the S2 (pre-facelift and 2024–2026 facelift), S3, S5 II, M4 Turbodiesel, T6 Hunter, T8 Pro, JS2, and JS5 model runs.

It drives the Bowden cable through a reinforced clevis-pin retention channel, which eliminates the cable-slip failure mode documented in JAC TSB-2025-BODY-014. One SKU — Koeep P/N KOE-JAC-HRH-001 — supersedes both OEM numbers, so a workshop serving mixed Refine and JS fleets carries a single handle.

Fitment Matrix: Does It Fit Your JAC?

Every cross-reference below is verified against the JAC global EPC (Electronic Parts Catalog) release 2026.Q1. If your model and years are in the table, the handle bolts straight in.

Two fitment notes: the T6 Hunter 4×2 and 4×4 share an identical cabin release assembly (JAC P/N 5207010LE010), so one handle covers both drivetrains, and the T8 Pro mounting bracket is dashboard-symmetric across RHD variants (South Africa, Australia, UK) and LHD versions (Latin America, Middle East).

Why Stock Handles Crack

The dominant failure mode across the Refine and JS light-commercial fleet is UV-induced polyamide embrittlement at the pivot boss. It bites hardest where annual solar irradiation exceeds 1,800 kWh/m² — the Middle East, Southeast Asia, Sub-Saharan Africa. If the handle in your S3 snapped at the pivot, this is the documented mechanism, not driver abuse.

The OEM PA6-GF20 used across 2015–2024 Refine S3, S2, M4, and T6 models is stiff, but elongation-at-break is only about 3.2% — almost no plastic deformation before brittle fracture. The Koeep handle is molded in PA66-GF30 to SAE J1639 with a HALS and 2.8% carbon-black UV-stabilizer package, validated to SAE J2527.

Over the full 2,500-hour xenon-arc cycle it keeps more than 85% of baseline notched Izod impact resistance. Economy handles in unreinforced PA6 lose 40% of notched Izod impact after just 1,200 hours of the same exposure.

• Durability factor: 1.9× over the OEM PA6-GF20 specification.
• Elongation-at-break: 4.8% vs about 3.2% stock.
• Heat-deflection temperature: 245°C vs 190°C (HDT at 1.82 MPa, ASTM D648).
• Climate range: −40°C to +125°C for Southeast Asian, Middle Eastern, and Latin American extremes.

How a Worn Handle Triggers Fault Codes

The JAC Body Control Module — a Bosch ME17.9.7 or UAES-contracted unit depending on market — monitors the hood-ajar microswitch circuit on pin BCM-C3-12. A fatigued handle prevents full cable retraction, the primary latch rests mid-stroke, and the circuit goes intermittently open.

• B0012-13 — Hood Ajar Sensor Circuit: Open. The core handle-wear code across Refine and JS platforms (ISO 15031-6 Body System, B0xxx).
• U0401-68 — Implausible Data Received from BCM. Logged on 2024+ CAN-FD JS5 models when the microswitch chatters across its threshold during vibration (ISO 15031-6 Network Communication, U0xxx).
• P0455-P0457. Secondary EVAP readiness flags on China 6b-RDE compliant 2026 models, set when a false hood-ajar status blocks the leak-detection routine.

Watch also for B0010-series body-control DTCs: hood-ajar sensor misreads caused by incomplete latch reset due to cable slack are often traceable to a worn or cracked handle pivot. Left alone, fault memory can escalate and light the MIL under the 2026 China 6b-RDE OBD framework.

On 2024+ JS5 and JS2 models with the Bosch MG1UA080 gateway, a correctly seated cable keeps hood-status frames stable at the specified 10 Hz refresh rate. The handle's precision-molded clevis channel is what seats the cable that way.

Diagnose Before You Order

1. Inspect the pivot boss for wear or hairline cracks. On T8 Pro trucks in high-UV service, fatigue cracking typically shows at the 80,000–120,000 km mark.
2. Measure cable free-play at the latch end. Spec is 0.5–1.2 mm; more than 3 mm means the handle is degraded.
3. Replace, clear, reset. Fit the new handle, clear the DTCs, and perform a BCM reset via ignition cycle.
