Specs & reference OEs (module P/N): ACTC31A04 marking; 12V coil (≈110 Ω), double-make 2 Form A (1 Form U), sealed, PCB 6-pin, nominal switching 30A @14 VDC; designed for Smart Junction Box/IPDM use. Compatible with IPDM controller P/N 284B6-ZE03B/284B6-ZE03C that contain this relay (match by the code printed on your relay body before purchase). Note: vehicle makers typically service the full IPDM as an assembly; this is the board-level relay inside
Operation & install location: Compatible with engine-bay IPDM/fuse box (battery area). Procedure (tech skill required): disconnect battery, remove IPDM cover, release module, extract PCB, desolder the failed relay, solder the new ACTC31A04, reassemble and test. Typical loads controlled by these high-load PCB relays include cooling fan, lighting and similar circuits within the IPDM. (ESD-safe tools recommended.)
Compatibility — Titan (IPDM ZE03B/ZE03C years): Compatible with 2009, 2010, 2011, 2012, 2013, 2014, 2015 Nissan Titan IPDM Fuse Box Relay (engine-bay IPDM). Match by module P/N 284B6-ZE03B/ZE03C and relay code “ACTC31A04” on the PCB.
Compatibility — Armada (IPDM ZE03B/ZE03C years): Compatible with 2009, 2010, 2011, 2012, 2013, 2014, 2015 Nissan Armada IPDM Fuse Box Relay (engine-bay IPDM). Verify by IPDM P/N 284B6-ZE03B/ZE03C and relay body code before ordering.
Compatibility — Frontier (IPDM ZE03B/ZE03C years): Compatible with 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019 Nissan Frontier IPDM Fuse Box Relay. Verify your truck's IPDM P/N 284B6-ZE03B/ZE03C and confirm relay code “ACTC31A04” on the PCB.
Compatibility — Xterra (IPDM ZE03B/ZE03C years): Compatible with 2010, 2011, 2012, 2013, 2014, 2015 Nissan Xterra IPDM Fuse Box Relay. Check your IPDM P/N 284B6-ZE03B/ZE03C and match the relay's body code.
Compatibility — Pathfinder (IPDM ZE03B/ZE03C years): Compatible with 2010, 2011, 2012 Nissan Pathfinder IPDM Fuse Box Relay. Confirm IPDM P/N 284B6-ZE03B/ZE03C and “ACTC31A04” on the removed relay before install.
Why match by module P/N & code: Newer black-housing IPDMs ZE03B/ZE03C supersede earlier versions; teardowns show internal relays including ACTC31A04 on these boards. Always open the module to visually confirm the relay code and board layout prior to ordering/installation.
Complementary items for related faults: If multiple high-load positions show heat damage or if the board is moisture-affected, replacing the complete IPDM (Compatible with 284B6-ZE03B/ZE03C) can be appropriate. Some ZE03 boards also contain other relay types (e.g., ACTB2LH3A23, ACP331) that may fail; inspect and service as needed
Description
ACTC31A04 12V 6-Pin PCB Relay — compatible with Nissan IPDM (Smart J/B) modules P/N 284B6-ZE03B/ZE03C. Match by the code printed on your original relay.
Key Specs: 12V DC coil (~110 Ω), double-make 2 Form A (1 Form U), sealed construction, PCB 6-pin, nominal switching 30A @ 14V DC.
Where it fits: Compatible with the engine-bay IPDM/fuse box (battery area). This is the board-level relay inside the module.
Typical function: High-load circuits within the IPDM (e.g., cooling fan/lighting and similar Smart J/B loads).
Install notes: Disconnect battery → remove IPDM → open housing → extract PCB → desolder failed relay → solder ACTC31A04 → reassemble and test. Use ESD-safe tools and inspect for heat or moisture damage.
Compatibility check: Confirm your vehicle uses IPDM 284B6-ZE03B or 284B6-ZE03C and verify the original relay body is marked “ACTC31A04.”
Complementary service: If multiple positions are heat-stressed or the board is corroded, consider replacing the complete IPDM (Compatible with 284B6-ZE03B/ZE03C).
