The remedy
Dealer will reroute the egr wiring harness to prevent any contact between the egr switch mounting bracket and the air cleaner assembly. Also, the engine wiring harness at the back of the generator will be modified by installing a terminal end connector at no charge to owner.
Vehicle description: passenger vehicles equipped with diesel engines.system: exhaust/crankcase emission control devices; egr wiring harness.consequences of defect: a wire in the exhaust gas recirculation (egr) wiringharness may become pinched between the air cleaner assembly and the egrmounting bracket. If this occurs, the insulation on the pinched wire can wearthrough, causing a short. The fusible link designed to stop the flow of currentin this situation IS bypassed by a wire in the engine wiring harness. As aresult, current will continue to be drawn from the battery through the ignitioncircuit.consequences of defect: this situation could cause overheating of the wiring,resulting in a vehicle fire, personal injury to passengers, and vehicle damage.
