⚠️ WARNING: Never install or replace an ECU without proper diagnostic tools and security access.
Park securely and apply parking brake.
Turn off ignition and disconnect both battery terminals.
Wait 3–5 minutes for system discharge.
Locate the ECU (usually under dash or on frame rail).
Remove protective cover and clean area.
Take photo of wiring layout.
Unplug multi-pin connector carefully.
Inspect pins for corrosion, bending, or overheating signs.
Unscrew mounting brackets or bolts.
Gently remove unit — avoid shock or static discharge.
Mount new unit securely using original hardware.
Ensure grounding strap is connected properly.
Torque screws to ~8–10 N·m.
Align connector correctly and push firmly until it clicks.
Secure secondary locking lever (if equipped).
