2016 Isuzu Truck CAUTIONARY NOTES: Electrical Sensitivity and Battery Relocation Warning Starting with the 2011 Model year Diesel and 2012 Model year Gas N series, these products are more sensitive to poor electrical integrity of the starting circuit when compared to previous year models. This is due to the ever increasing electrical demands from the base vehicle that includes the new emissions componentry as well as more sophisticated engines and transmissions. The control modules for these devices require healthy electrical circuits without significant voltage drops through the supply and return circuits.
A relocation or modification of batteries coupled with insufficient wire gauge, poor terminal crimps, weak conductivity to frame rails , terminal corrosion, or loose bolts, could contributed to a possible no start condition. All Fluids and Lubricants Caution Any fluids or lubricants added to the chassis during the final manufacturing process must meet Isuzu’s fluids and lubricants specifications. These fluids and lubricant specifications vary based on model year and chassis model code.
A recommended fluids list based on model and model year can be found in the Vehicle Owner’s Manual or on line at www.isuzutruckservice.com Low Speed Applications for N-Series Chassis Any low speed vehicle applications using the Aisin Transmission such as sweeper, highway striping and road side mowing airport service must adhere to the following guidelines in order to prevent the over heating of the automatic transmission fluid. Factory Recommendation: Select Range 1 for low speed operations under 11 mph, (18km/h). Select Range 2 for low speed operation under 22 mph, (36km/h).
Auxiliary Transmission Cooler Warning Installation of Auxiliary automatic transmission fluid cooler will void warranty on transmission/engine. Transmission Temperature Warning Lamp Automatic transmission fluid temperature warning lamp illuminates over 140 Centigrade/284°Fahrenheit. Tapping into Engine Cooling System Do not connect any auxiliary heating devices to the chassis cooling system. The chassis cooling system is part of the vehicle emission system and is used to thaw DEF fluid and meet mandatory emission thaw times.
Brake Override Logic The ECM logic in the2013 NPR and 2014 NPR-HD, NQR, NRR model year chassis has been revised to adopted Brake Override Logic that will reduce engine RPM to idle RPM when the brake and accelerator pedals are applied simultaneously. This ECM logic has been adopted to enhance the safe operation of the vehicle. The brake override logic disables the accelerator pedal input and protects against vehicle malfunction in cases where the accelerator pedal and brake pedal are operated simultaneously, or if unintended driver acceleration pedal operations are detected.
