Introduction 3

Service Procedures and Tool Usage

Anyone using a service procedure or tool not recommended in this manual must first satisfy himself thoroughly that neither his safety nor vehicle safety will be jeopardized by the service method he selects. Individuals deviating in any manner from the instructions provided assume all risks of consequential personal injury or damage to equipment involved.

Also note that particular service procedures may require the use of a special tool(s) designed for a specific purpose. These special tools must be used in the manner described, whenever specified in the instructions.

4 Introduction

DANGER

Before starting a vehicle, always be seated in the driver's seat, place the transmission in neutral, apply the parking brakes,

and push in the clutch pedal. Failure to follow these instructions could produce unexpected vehicle movement, which can result in serious personal injury or death.

DANGER

Before working on a vehicle, place the transmission in neutral, set the parking brakes, and block the wheels. Failure to follow these instructions could produce unexpected vehicle movement, which can result in serious personal injury or death.

DANGER

Engine-driven components such as Power Take-Off (PTO) units, fans and fan belts, driveshafts and other related rotating assemblies, can be very dangerous. Do not work on or service engine-driven components unless the engine is shut down. Always keep body parts and loose clothing out of range of these powerful components to prevent serious personal injury. Be aware of PTO engagement or nonengagement status. Always disengage the PTO when not in use.

DANGER

Do not work under a vehicle that is supported only by a hydraulic jack. The hydraulic jack could fail suddenly and unexpectedly, resulting in severe personal injury or death. Always use jackstands of adequate capacity to support the weight of the vehicle.

WARNING

When working on a vehicle by using wireless communication units, it is not always apparent to others that work is in progress on the vehicle. Certain activities, such as activation of certain

vehicle components or systems, can cause injury to persons close to the vehicle who are unaware of the ongoing activities.

Always keep a connected vehicle under close observation when using wireless communication units and inform other persons in the vicinity of the vehicle about the ongoing activities.

WARNING

The temperature of the exhaust system components during the regeneration process can exceed 500°C (1000°F). Various factors (including ambient air temperature (AAT) and duration of the regeneration process) determine when these components will return to normal operating temperature after regeneration has completed. Be extremely careful around these hot components. Contact with these components can result in serious personal injury.

CAUTION

Before towing the vehicle, place the transmission in neutral and lift the rear wheels off the ground, or disconnect the driveline to avoid damage to the transmission during towing.

Introduction 5

CAUTION

When regeneration occurs, the temperature of the exhaust will be elevated. DO NOT park the vehicle with the exhaust outlet under low hanging overhead flammable objects such as trees, awnings, etc., that could be damaged by elevated exhaust temperatures. DO NOT attempt to regenerate inside a garage or enclosed area if the tail pipe is attached to an exhaust ventilation system as the hose material may not be rated for the high temperature.

CAUTION

Failure to perform a regeneration in a timely manner may result in engine derate, clogged Aftertreatment Diesel Particulate Filter (DPF) or damage to the filter.

CAUTION

When the inhibit position is pressed, the DPF switch will remain in a locked position. It is important, therefore, to immediately set the switch back to the

neutral position when safe to do so. Failure to set the switch back to the neutral position may result in an engine derate, clogged or damaged DPF.

REMEMBER,

SAFETY . . . IS NO ACCIDENT!

6 Introduction

Every possible occurrence that may involve a potential hazard cannot be anticipated. Accidents can be avoided by recognizing potentially hazardous situations and taking necessary precautions. Performing service procedures correctly is critical to technician safety and safe, reliable vehicle operation.

The following list of general shop safety practices can help technicians avoid potentially hazardous situations and reduce the risk of personal injury. DO NOT perform any services, maintenance procedures or lubrications until this manual has been read and understood.

•Perform all service work on a flat, level surface. Block wheels to prevent vehicle from rolling.

•DO NOT wear loosefitting or torn clothing. Remove any jewelry before servicing vehicle.

•ALWAYS wear safety glasses and protective shoes. Avoid injury by being aware of sharp corners and jagged edges.

•Use hoists or jacks to lift or move heavy objects.

•NEVER run engine indoors unless exhaust fumes are adequately vented to the outside.

•Be aware of hot surfaces. Allow engine to cool sufficiently before performing any service or tests in the vicinity of the engine.

•Keep work area clean and orderly. Clean up any spilled oil, grease, fuel, hydraulic fluid, etc.

•Only use tools that are in good condition, and always use accurately calibrated torque wrenches to tighten all fasteners to specified torques. In instances where procedures require the use of special tools which are designed for a specific purpose, use only in the manner described in the instructions.

•Do not store natural gas powered vehicles indoors for an extended period of time (overnight) without first removing the fuel.

•Never smoke around a natural gas powered vehicle.

Electronic Malfunction Indicator

The electronic malfunction indicator, amber in color, illuminates to alert the driver of an electrical problem with the Vehicle Management and Control (V-MAC) IV system. The V-MAC IV system does a self-test when the ignition key is turned to the ON position. The electronic malfunction indicator stays on while this test is being performed (approximately six seconds). After the self-test is completed, the indicator will turn off and remain off unless a problem is detected by (V-MAC) IV. If the indicator turns on while the vehicle is being driven, (V-MAC) IV has detected a problem. In most circumstances, the vehicle will operate even though the indicator is on; however, engine performance may be affected.

For an explanation of fault code activation and interpretation, and a complete listing of these codes, please refer to “Diagnostic Trouble Codes (DTCs)”, page 54 of this manual.

Shutdown Warning Indicator

The Shutdown Warning indicator, red in color, illuminates if the Engine Coolant Level (ECL) is below the minimum level allowed, the Engine Oil Pressure (EOL) is below the minimum allowed, the Engine Coolant Temperature (ECT) or aftertreatment Diesel

Particulate Filter (DPF) soot level trigger are above the maximum allowed. Some vehicles also have optional shutdown functions available when the transmission temperature or engine Exhaust Gas Temperatures (EGT) are above maximum allowable limits.

During a shutdown event, V-MAC IV also provides an audible alarm. The alarm will also sound and the red shutdown indicator will turn on when V-MAC IV detects a problem or excessive periods of idling. Shutting the engine down is warranted.

The shutdown warning indicator is usually located on the left-hand side on the dash cluster.

W3036501

Engine Shutdown Warning Indicator (Red)

V-MAC IV can be programmed to actually shut down the engine if conditions warrant (low coolant, low EOL, high Engine Oil Temperature (EOT), high ECT, high engine EGT or high automatic transmission oil temperature if so equipped). Shutdown is mandatory for Crankcase Pressure (CCP). With this option enabled, the engine will automatically shut down within approximately 30 seconds after the red SHUTDOWN indicator turns on and the alarm activates (provided the vehicle is not moving above the road speed threshold).
