상품 특징

• 12V 40A 5-Pin Automotive Power Relay (electromagnetic switching relay): helps control high-current 12V loads using a low-current trigger. Compact plug-in blade relay, 40A rating; contact form 1Z / changeover (5-pin style). Marking/OE#: ZTV4 012-1Z (ZTV40121Z; may also appear as ZTV4/012-1Z). Useful for relay-controlled circuits such as cooling fan, fuel pump, A/C clutch, horn, lights, or other accessory loads when your original relay matches the same marking + coil voltage + pin layout.
• Install/replace tips: disconnect the negative battery cable first. Locate the relay by the diagram on the fuse/relay box cover or service manual, then pull the old relay straight up (use a relay puller if tight). Before installing, compare: (1) same OE marking, (2) same pin count (5-pin), (3) same terminal layout/numbering on the case, and (4) socket condition (no heat damage/corrosion). Press the new relay fully into the socket and test the circuit. Common locations vary by vehicle but are often in the under-hood fuse/relay box or an interior relay panel—confirm your exact location and function in the owner’s manual.
• Fitment (verified-by-number approach): no reliable public catalog was found that maps OE#ZTV4 012-1Z to specific North-American year/make/model lists. To avoid incorrect fitment claims, please confirm compatibility by (A) the OE marking on your original relay, (B) coil voltage (12V), and (C) the relay footprint/pin layout shown on your fuse-box diagram or service manual. If any of these do not match, do not install.
• Common symptoms a failing relay may be associated with (depending on circuit): intermittent/no operation of cooling fan, fuel pump not priming, A/C clutch not engaging, lights or horn not switching, or random power cutouts. This is a general-purpose 12V 40A 5-pin changeover relay style; use it only where the vehicle wiring diagram calls for a matching 5-pin relay and the original relay uses the same terminal mapping.
• Related markings & what they mean: ZTV4/012-1Z = 12V 5-pin style; “-C” versions may include a mounting tab/bracket depending on supplier. ZTV4/012-1H is a different 12V 4-pin style—4-pin and 5-pin relays are NOT interchangeable unless your wiring diagram explicitly shows the same terminal functions. Optional complementary spare: if your fuse/relay box uses multiple identical relays for different circuits, keeping an extra matching relay on hand can help with quick troubleshooting (swap-test), but always return relays to their original positions after testing.
• Quality/inspection & testing: inspect the socket for overheated terminals (melted plastic, discoloration) which can cause repeat failures. For a quick bench check, you can listen/feel for an audible click when the coil is energized with 12V (follow safe handling; avoid shorting terminals). If you’re unsure about terminal functions, use the pin diagram printed on the relay case and your vehicle’s wiring diagram—do not guess. This listing is for the relay only (no harness/socket unless stated in your package).
