Truck Diagnostic System

What's the difference between Truck Diagnostic System and Premium Tech Tool?

Truck Diagnostic System is a very fast, light tool that quickly displays truck fault codes within one minute while Premium Tech Tool supports the need for more in-depth diagnostics and extensive parameter changes.

See Comparison Chart for specifics.

Who is the target market for Truck Diagnostic System?

It was developed primarily for fleets that have light diagnostic needs and want vehicle trip reporting capabilities.

Are the parameter changes password protected?

Body Builder Support

What is the minimum RPM I should operate my PTO, so that my vehicle will perform Regeneration during PTO mode?

Regeneration in PTO mode is when a vehicle is being operated in PTO mode and a diesel particulate filter (DPF) regeneration is commanded. The engine must run at a speed above the minimum speeds listed in the tables in Body Builder Manual, Section 9, Table of Contents / Regeneration in PTO Mode. The minimum speed setting can be affected by ambient temperature and/or altitude.

On Mack mDRIVE™, with PTO engaged while in neutral, and then selecting Drive the PTO stops turning. Why?

Remember that the mDRIVE is an automated manual transmission with a clutch. With the PTO engaged while in neutral, when selecting Drive, the clutch is released, then the transmission shifts into gear. When the driver takes his foot off the brake pedal and presses the throttle pedal, the clutch will reengage and the PTO will start to turn again. The transmission will not shift gears and driver is limited to about 6 MPH.
Transmission-mounted PTOs are primarily used for stand-still operation, with the gearbox in neutral. However it is possible to engage PTO in vehicle speeds up to 6 MPH. If the vehicle has a moving PTO operation, an mDRIVE with a REPTO or FEPTO is recommended.

What is the procedure for operating an mDRIVE mounted PTO?

Manually place the transmission in the desired PTO operating range (N1/N2) while stationary. Do not shift the range with the PTO engaged, or damage may occur. Engage the PTO also while stationary. Move the vehicle up to the operational speed, which can vary slightly based on rear axle ratio, drive tire size, engine RPM and transmission gear selected.

Can the mDRIVE shift gears with PTO active?

The mDRIVE cannot shift gears with the PTO active, as the PTO would add torque and inertia load on the synchronization components.

Can the mDRIVE rear-mounted PTO be engaged while driving over 6 MPH?

The PTO cannot be engaged while driving over 6 MPH as the activation mechanism is not designed for any differential speed between PTO and gearbox. If the PTO is turned on while driving over 6 MPH, the PTO switch will illuminate and the PTO indicator will appear in the dash; however the PTO will not engage. The vehicle must be brought to a complete stop, transmission shift pad set to neutral then select the range (N1/N2) while stationary.

During the body upfit, are reprogramming the PTO parameters so the truck operates to the customer's requirements covered by the Mack warranty?

PTO parameter programming is considered part of the body uplift expense. The selling dealer or body builder is responsible for the correct application and/or specification for a vehicle sold to a customer. Vehicle application issues are not covered by the Mack warranty.

Where do I locate a power and ground source for PTO installation?

Utilization of Body Builder connectors ordered and provided by Mack are strongly recommended as your power source for Body Builder PTO installation and operation. Tapping into wiring harnesses is not recommended as it may affect message transmission within the harness. Tapping into an OEM harness will void the warranty of the harness, should it be incorrectly used to supply power to PTO equipment. Be sure to consult with your local Mack dealer when ordering trucks to ensure proper connectors are supplied when the vehicle is manufactured. Ref: Section 3 of the Mack Body Builder Manual for the different body builder connectors that are offered.

Can I lock which Range my PTO is operated in to stop my drivers from over speeding my equipment?

Yes the mDRIVE transmission has parameters for PTO 1 and PTO 2 operation which will prevent drivers from shifting from Low to High Split: Split gear for transmission PTO 1 is P1AO5; 0 = Selectable, 1 = Low Split, 2 = High Split; Split gear for transmission PTO 2 is P1AO6; 0 = Selectable, 1 = Low Split, 2 = High Split

Certified Uptime Dealers

How is the Mack Certified Uptime Dealer concept different from other programs?

It's not a program, but rather a fixed operations process that's designed to drive consistency in the service experience—and uptime for you—for years to come.

How was the Certified Uptime Dealer solution created?

The solution was developed in conjunction with our Dealer Service Advisory Council. It was created within the dealership environment, using intelligence from the dealer network and incorporating dealership best practices. It's been piloted, tested and proven successful by your Mack dealers.

What areas of service do Mack Certified Uptime Dealers address?

Too often trucks with short repairs get backlogged behind trucks requiring longer repairs. This creates inefficient bottlenecks in the service process and unnecessary downtime. All aspects of a Mack Certified Uptime Dealer are designed to make a positive impact on your uptime and satisfaction.

Other OEMs are working to improve uptime. How is a Mack Certified Uptime Dealer different from the competition?

There are four primary differences that distinguish a Mack Certified Uptime Dealer from other OEM initiatives.

CUSTOMER FOCUSED REQUIREMENTS: The process focuses only on the requirements that make a real difference to you.

REDUCTION IN TOTAL REPAIR TIME: The process is a comprehensive approach that reduces "wasted time" through the duration of the repair, from initial check-in to notification of repair completion.

CHECK-IN EXPERIENCE: The process integrates a code read and ASIST to speed up check-in and inspection. This leading technology provides fast, transparent information to you so you can quickly start making decisions for your trucks, drivers and loads earlier in the repair process.

COMMUNICATION: The process provides on-going communication at each step in the repair process, enabling you to make faster, smarter decisions for your business.
