Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.There have been some isolated instances of the exhaust gas valve (NRS) not responding, accompanied by a diagnostic trouble code 112-2 EGR Valve Not Responding. Diagnosis indicates that the valve has a build-up of excessive soot. The exhaust gas valve (NRS) seizes due to erosion of the clearance between the poppet valve stem and guide bush.An improved design of exhaust gas valve (NRS) has been introduced.Safety Section
Sulfuric Acid Burn Hazard may cause serious personal injury or death.The exhaust gas cooler may contain a small amount of sulfuric acid. The use of fuel with sulfur levels greater than 15 ppm may increase the amount of sulfuric acid formed. The sulfuric acid may spill from the cooler during service of the engine. The sulfuric acid will burn the eyes, skin and clothing on contact. Always wear the appropriate personal protective equipment (PPE) that is noted on a material safety data sheet (MSDS) for sulfuric acid. Always follow the directions for first aid that are noted on a material safety data sheet (MSDS) for sulfuric acid.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Ensure that the wiring harness assembly is correctly routed and the cable straps are not over tightened. Over tightening of the cable straps will damage the wiring harness convoluting.
