⚠ Failure Pattern Analysis

▸ Common Failure Symptoms:

• Intermittent fan operation (works only on high speed)

• Engine overheating in traffic

• Check Engine Light with codes:

  • P0480 (Fan Control Circuit Malfunction)

  • P0691 (Fan Control Circuit 1 Low)

▸ Typical Failure Causes:

• MOSFET transistor burnout (Q1-Q3 components)

• Water ingress through degraded seals

• Connector pin corrosion (CP-47 connector)

🔌 Installation Protocol

1. Pre-Installation Checks:

   • Verify fan motor resistance (1.5-2.2Ω at 20°C)

   • Check 12V supply at connector pin 3 (KOEO)

   • Inspect wiring harness for chafing

2. Installation Steps:

   • Disconnect battery (wait 15 minutes)

   • Remove front bumper cover (Torx T25)

   • Transfer thermal paste to new module

   • Torque bolts to 8-10 N·m

3. Post-Installation:

   • Perform ECM reset

   • Test fan operation through OBDII:

     • Stage 1: 40% duty cycle (A/C off)

     • Stage 2: 70% duty cycle (A/C on)

     • Stage 3: 100% (overheat protection)

📜 Technical Service Bulletins

• Land Rover TSB LTB00514v3: Requires software update for 2013-15 models

⚠ Critical Notes

✖ Not Compatible With:

• 2018+ models (redesigned cooling system)

• Plug-in hybrid variants

• Vehicles with dual-speed fan setups

For precise verification:
① Provide 8th VIN digit (engine code)
② Check existing fan operation stages
③ Verify production month/year
