Question 1

Where can I pick up the RPM or Vehicle Speed Signal?

Accepted Answer

The Ram vehicles utilize “CAN BUS”-style communication and therefore do not have traditional hard wiring for these signals. At this time, Ram vehicles do not offer this ability.

Question 2

How do I hook up remote startDisclaimer: Check state and local laws regarding use of remote start systems./stop on the Ram trucks?

Accepted Answer

In order to operate a remote start/stop system on a Ram truck, you need to add some additional hardware to the ignition sense circuit. In the Body Builder’s Guide, under the “Ram Chassis Cab/Electrical Wiring Information/Aerial Device Start/Stop Instructions,” you will find instructions and a basic electrical circuit you can put together to make your remote start/stop system work.

Question 3

Does Ram sell a remote startDisclaimer: Check state and local laws regarding use of remote start systems./stop kit?

Accepted Answer

No, not at this time. All additional components described above are the responsibility of the upfitter to purchase, build and interface correctly with the truck.

Question 4

Does Ram provide a remote throttle kit?

Accepted Answer

No. There are, however, aftermarket companies that do provide kits. If you wish to make your own remote throttle kit, you will need a 0-to-1,000-ohm potentiometer. You can find the required circuit definition in the Body Builder’s Guide under “PTO Operation and Installation Guide.”

Question 5

What are the top speeds on Ram Chassis Cabs?

Accepted Answer

The vehicle top speeds are determined by the tire speed ratings. The Ram 3500 Chassis Cab truck's top speed is 106 mph. The Ram Chassis Cab models have been rerated to a maximum speed of 87 mph. This requires a unique tire with an N speed rating. Replacement tires must have this speed rating as well as the appropriate size and weight rating.

Question 6

What can I install on the chassis?

Accepted Answer

Question 7

How does one become an approved upfitter for Ram trucks?

Accepted Answer

The Ram brand does not require an approval process for individual upfitters. We recommend using a current National Truck Equipment Association (NTEA) member in good standing.NTEA members may be eligible for the On The Job customer incentive program for vehicle purchasers.

Question 8

How do I ensure my 2008 Ram vehicle is ARB-compliant?

Accepted Answer

These regulations do not apply to the 2500/3500 pickup trucks. These regulations do not apply to the 3500 Chassis Cab. Vehicles over 14,000 pounds GVW have two options: Implement an automatic engine shutdown after five minutes at idle. Certify at idle and at 11,000 rpm to NOx idling emissions standard of 30 g/hr (requires driver-side hood-mounted sticker). 'Certified Clean Idle' provides the following advantages: Offers flexibility for customers who may need to idle for longer than five minutes (other manufacturers have selected different idle shutdown strategies). Allows end user to idle in ARB states (CA) and still comply with regulations and avoid fines

Question 9

What is the clean idle emission regulation?

Accepted Answer

Starting January 1, 2008, several states enacted a law that prohibits diesel-powered on-road vehicles from idling unattended for longer than five minutes. This applies to vehicles with a GVW of greater than 14,000 pounds. Cummins® engines produced after 1/1/08 (with the XKH clean idle emissions option) on the Ram 4500/5500 are exempt from this requirement because they emit less than 30 grams of NOx per hour. These exempt vehicles are required to have a Clean Idle label attached. This label is serialized to the VIN of each truck and cannot be transferred. Below is a list of frequently asked questions concerning the clean idle emissions system. How do I order a clean idle emissions vehicle? The truck must be ordered with 50 State Emissions (sales code NAS), not Federal Emissions (sales code NAA). Ram truck sales code XKH must be ordered. How do I know if a vehicle is clean idle certified? It will have the clean idle label applied to the driver’s side fender. Can I convert a vehicle that does not have the clean idle label? If the truck is coded for NAS Emissions, your Ram vehicle dealer can order a label. Can I get a label for a truck built before January 2008? No, this certification applies only to vehicles built after January 2008. How do I get a replacement clean idle label if mine is damaged? The dealer can order a replacement label.

Question 10

What is the voltage monitoring and auto idle up control?

Accepted Answer

This system monitors the electrical load on the vehicle at idle and if it determines that the load exceeds the output of the alternator at idle, it automatically increases the engine RPM.

Question 11

Why are my turn signals blinking rapidly?

Accepted Answer

The rear turn signal lamps may be hooked up incorrectly. Common causes are the use of aftermarket LEDs without adding a resistor or having a Ram Dealer disable “rear bulb out detection”. It may also be caused by your upfitter having incorrectly used the trailer tow circuits, thus leaving the OEM rear lighting circuits open.

Question 12

How do I add to or change my vehicle's lighting?

Accepted Answer

Question 13

I lost my incomplete vehicle document; how do I get a new one?

Accepted Answer

You can produce your own legitimate Incomplete Vehicle Document by printing the document at the link below and taking a photograph of the certification label on the driver’s door opening. INCOMPLETE VEHICLE DOCUMENT

Question 14

Question 15

What is in the Ambulance Prep Package?

Accepted Answer

• 220A alternator • Limited slip differential • HVAC taps; fittings for rear HVAC unit • Voltage monitoring and auto idle up control Note: You must have a diesel engine.

Question 16

Can I retrofit a 2008 or 2009 4500/5500 truck with the factory Dodge aluminum wheels?

Accepted Answer

They will fit, but you will need to change the wheel studs to slightly longer ones to account for the thicker aluminum wheel.

Question 17

Can I install a remote throttle device on a Ram truck to use with a PTO application?

Accepted Answer

Yes. Wiring circuits are provided near the bell housing of the transmission that provide an interface between the remote throttle device and the engine controller.

Question 18

Do all Ram Chassis Cabs come with PTO capability?

Accepted Answer

While all the Chassis Cabs (with the exception of the Chassis Cab with the 5.7L gas engine and automatic transmission) are PTO-capable, you must order your vehicle with the LBN sales code (PTO prep group) in order to have your vehicle PTO-ready from the factory.

Question 19

What is included in the PTO Prep Group (Sales Code LBN)?

Accepted Answer

For diesel automatics, the group contains: • Installed floorpan patch panel (available through Mopar®) • Cruise switches (must be factory installed) • Factory-enabled PTO controller software. For diesel manuals, the group contains: • Cruise switches (must be factory installed) • Clutch up-stop switch (available through Mopar®) Service Part Kit Number • Factory-enabled PTO controller software

Question 20

What is the maximum vehicle speed when mobile mode PTO is active?

Accepted Answer

During active mobile PTO, the vehicle speed is limited to 50 mph.

Question 21

My Chassis Cab truck was built without the PTO Prep Group. Can it be converted?

Accepted Answer

Yes, but only if the truck has a diesel engine and has factory cruise control. Visit this link to find out what is in the PTO prep group: What is included in the PTO prep group (sales code LBN)?
