Professional Installation Required
Involves working on electrical and pneumatic systems.
Must be performed by trained technicians familiar with AMT systems.
Disconnect Battery Before Work
Prevents short circuits and protects ECU/solenoid coil.
Inspect Air Lines First
Check connected hoses for cracks, kinks, or moisture buildup.
Drain air tanks before disassembly.
Ensure Clean Air Supply
Replace air filter/dryer elements regularly.
Moisture causes rust and internal valve sticking.
Check Electrical Connections
Inspect plug pins for corrosion or bending.
Use dielectric grease on terminals to prevent oxidation.
Verify Voltage Compatibility
Confirm it's 24V DC — do not use 12V version by mistake.
Test All Functions After Replacement
Perform full gear cycle test (1st → 10th).
Listen for proper actuator engagement.
Avoid Forced Installation
Do not overtighten mounting bolts — can crack housing.
Torque typically ~8–10 Nm.
Use Genuine or High-Quality Replacements
Low-cost imitations often fail early due to weak coils or poor seals.
Storage Advice
Keep sealed in anti-static bag until installation.
Store in dry indoor environment.
