Worldwide Diagnostic System (WDS)
Principles of Operation
WARNING:This procedure involves fuel additive handling. Be prepared for fuel additive spillage at all times and always observe fuel handling precautions. Failure to follow these instructions may result in personal injury.
WARNING:Eye, hand, ear protection and protective clothing are required to be worn during any general service or removal and installation service procedure of fuel additive system components. Failure to follow this instruction may result in personal injury.
WARNING:In case of fuel additive fluid contact with the skin or the eyes, flush immediately with water for a minimum of 15 minutes and seek prompt medical attention. Failure to follow these instructions may result in personal injury.
WARNING:If fuel additive fluid is swallowed, call a physician immediately. Rinse mouth immediately with water, do not induce vomiting. Failure to follow these instructions may result in personal injury.
WARNING:Always provide adequate ventilation when working on the fuel additive fluid system or related components. Failure to follow these instructions may result in personal injury.
WARNING:Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.
CAUTION:Make sure the workshop area in which the vehicle is being worked on is as clean and as dust free as possible. Foreign matter from working on clutches, brakes or from machining or welding operations can contaminate the fuel system and may result in later malfunction.
The fuel additive system is an on-board system that allows the injection of an additive at each refueling operation by the customer. The additive quantity is proportional to the fuel quantity that has been added. The fuel additive system module controls the amount of additive fluid entering the fuel tank at each refueling, A switch mounted on the fuel filler flap is used to detect the start of the refueling event and the fuel gauge that is mounted within the fuel tank informs the fuel additive tank module the quantity of actual fuel added.
Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of leakage and mechanical or electrical damage.
