16865/P0481/001153 - Coolant Fan Control Circuit 2: Electrical Malfunction

Possible Causes

  • Fuse(s) faulty
  • Coolant Fan Control Module (J293) faulty
  • Coolant Fan 2 (V177) restricted/jammed
  • Wiring and/or Connector(s) from/to Coolant Fan Control Module (J293) faulty
  • Wiring and/or Connector(s) from/to Coolant Fan 2 (V177) faulty

Possible Solutions

  • Check Fuse(s)
  • Check Coolant Fan Control Module (J293)
    • Perform Output Test
  • Check Coolant Fan 2 (V177) for Restriction/Blockade
    • Check for Foreign Objects and Accidental Damage as well as Restrictions
  • Check Wiring and/or Connector(s) from/to Coolant Fan Control Module (J293)
  • Check Wiring and/or Connector(s) from/to Coolant Fan 2 (V177)

Special Notes

  • Remove the Coolant Fan Fuse(s) for Safety Reasons before checking it
  • When found in a 2011+ 3.0TDI (4H) Chassis A8 check the wiring near the engine controller for chaffing. The Black and Yellow trace wire damage in this example picture may be helpful
