⚠️ Important Information
1️⃣ Permanent fault codes & mechanical repairs: This scan tool does NOT fix permanent fault codes resulting from actual hardware failure. Always address the root mechanical or electrical issue. Do not rely solely on code clearing without physical repair.
2️⃣ OEM security restrictions: Due to manufacturer safety strategies, some engine or transmission ECUs may restrict aftermarket tool access. This device may not read 100% of systems — normal for aftermarket tools.
3️⃣ Service limitation: This reader does not offer advanced reset services beyond code clearing. It does NOT perform DPF regen, injector coding, parameter changes, ECU reprogramming, or advanced resets.
💡 Pro tip: For best results with New Holland T4.55/T4.65/T4.75, connect via the round 9‑pin Deutsch (J1939) adapter included. Always fix underlying mechanical faults before clearing DTCs to ensure safe operation.
