My 2005 Ram 2500 cummins is making a grinding

Its more then likely a wheel bearing. Try taking it down the highway and turning left and right erratically. Almost like a swerve. If you hear the noise I would put money down on the wheel bearing.

My dodge ram 2500 cummins is making a rattling noise when its idling

Depends what the rattling is really... If it's the engine , could need a valve adjustment... I've also heard of torque converters make a rattle when going bad, but only when in drive or reverse

2004 Dodge 2500 diesel 4 x 4 (BRAKES LOCKING UP

Need to check for codes. Need a scanner hooked up and test drive to be able to see what happening. Hopefully someone did not add the wrong fluid because this could contaminate and destroy all rubber parts in the brake system and cause swelling issues.

LEFT TRAILER TURN SIGNAL DOES NOT WORK

I have seen once before that the fuse box was bad on a 2003 Dodge 3500. I had power in and nothing out. We had to replace the box. Not cheap! Hope it is simple like a loose connection though. I think I had to pull the inner fender on the drivers side to access the bottom of the fuse box. Pain in the ****, but...

Trailer Wiring Standards (Color Codes/Plug Marks)

Hello all,

For those of you that have or occasionally borrow trailers and look at the wiring plugs with disdain (I mean face it they don't make sense, ground is white, +12vdc is black, etc), this is for you.

This will show you how to wire trailers with seven, six and four pin connectors

Plug Types/Application
7 Way - RV Trailers, Horse and Utility Trailers
6 Way - Horse, Stock and Utility
4 Way - Utility Trailers

Columns are: Color, Function, Mark on the plug.

Seven wire Trailer plugs (Large trailers with a battery and electric brakes):

Horse, stock or utility trailers:

White = Ground - 1
Blue = Electric Brakes - 2
Brown = Tail and clearance lights - 3
Black = Battery, aux power - 4
Yellow = Left turn/Brake - 5
Green = Right turn Brake - 6
Orange or Purple (not both) = Auxilliary or Reverse - 7

Recreational Vehicle:
White = Ground - 1
Blue = Electric Brakes - 2
Green = Tail and clearance lights - 3
Black = Battery, aux power - 4
Red = Left turn/Brake - 5
Brown = Right turn Brake - 6
Yellow = Auxilliary or Reverse - 7


Six wire trailer plugs:

Horse, stock or utility trailers:
White = Ground - GD
Yellow = Left turn/Brake -LT
Green = Right turn Brake -RT
Brown = Tail and clearance lights - TM
Red or Black (not both) = Battery, aux power - A
Blue = Electric Brakes - S

Recreational Vehicle: (color, use, plug mark)
White = Ground - GD
Yellow = Not used -
Brown = Right turn Brake - RT
Green = Tail and clearance lights -TM
Black = Battery, aux power - A
Red = Left turn/Brake - LT
Blue = Electric Brakes - S


Four wire plugs:
White = Ground
Yellow = Left turn/Brake
Green = Right turn Brake
Brown = Tail and clearance lights


Ground should be 10ga.
Others 14 ga

Best regards
Mike

2004 Ram 2500 Diesel 100k Lift pump not pumping out of banjo fitting at injection pump. Options before replacing LP. James

James, Since you are pulling a vacuum to draw the fuel to the fuel pump a very small pin hole will cause the pump to not draw fuel. On my Cummins I connect a fuel line to the tank side of fuel pump and ran it into a pail with diesel fuel to verify an air leak in the line to the tank. The ECM electronics control module on mine a 1999 turns the pump on. You could use a jumper 12 volt to the pump verify it is getting 12 volts. You should be able to hear it running. I replace the factory fuel pump on mine with a Fass pump and used a small relay to power the Fass pump without using the ECM and it works great. Keith (waymaker10)

Cummins wont start when cold

may be a check valve letting warm expanded fuel to slowly leak back to the tank causing hard start. When starting cold its harder to move the cold thick fluid. Check into it. Good luck..

2003 Dodge Ram 2500 5.7 Hemi, Red lighting bolt on

Hi, if you don't have a manual, you can get a free download here: http://www.dodge.com/en/owners/manuals/

The lightning bolt indicates a fault in the electronic throttle control. It is likely the rheostat/potentiometer in the accelerator position sensor is dirty or worn out. I have pasted info on the part below from autozone.com. If you replace the sensor, be sure to follow the calibration procedure at the end of the installation instructions. Please let me know if you have any questions and thanks for using FixYa.


Operation
The Accelerator Pedal Position Sensor (APPS) assembly is located under the vehicle battery tray. A cable connects the assembly to the accelerator pedal. A plastic cover with a movable door is used to cover the assembly.


NOTE The APPS is used only with the 5.7L V-8 engine.

The Accelerator Pedal Position Sensor (APPS) is a linear potentiometer. It provides the Powertrain Control Module (PCM) with a DC voltage signal proportional to the angle, or position of the accelerator pedal. The APPS signal is translated (along with other sensors) to place the throttle plate (within the throttle body) to a pre-determined position.
A mechanical cable is used between the accelerator pedal and the APPS assembly. Although a cable is used between the pedal and APPS, a mechanical cable is not used at the throttle body. Throttle plate position is electrically determined.

A mechanical cable is used between the accelerator pedal and the APPS assembly. Although a cable is used between the pedal and APPS, a mechanical cable is not used at the throttle body. Throttle plate position is electrically determined.


Removal & Installation
The APPS is serviced (replaced) as one assembly including the sensor, plastic housing and cable. The APPS assembly is located under the vehicle battery tray. Access to APPS is gained from over top of left / front tire.

  1. Disconnect negative battery cable at battery.
  2. Disconnect APPS cable at accelerator pedal.
  3. Remove wheel house liner at left / front wheel.
  4. Gain access to APPS electrical connector by opening swing-down door.
  5. Disconnect electrical connector.
  6. Remove 3 mounting bolts.
  7. Remove APPS assembly from battery tray.
  8. If cable is to be separated at APPS, unsnap cable clip from ball socket. Release cable from plastic housing by pressing on small cable release tab.

To Install:
  1. Install Accelerator Pedal Position Sensor (APPS) cable to accelerator pedal. Refer to Accelerator Pedal Removal / Installation.
  2. Connect electrical connector to APPS.
  3. If necessary, connect cable to APPS lever ball socket (snaps on).
  4. Snap APPS cable cover closed.
  5. Position APPS assembly to bottom of battery tray and install 3 bolts.
  6. Install wheelhouse liner.
  7. The 5.7L V-8 engine is equipped with a fully electronic accelerator pedal position sensor. If equipped with a 5.7L, also perform the following 3 steps:
    1. Connect negative battery cable to battery.
    2. Turn ignition switch ON, but do not crank engine.
    3. Leave ignition switch ON for a minimum of 10 seconds. This will allow PCM to learn electrical parameters.
      NOTE The DRB III Scan Tool may also be used to learn electrical parameters. Go to the Miscellaneous menu, and then select ETC Learn.

  8. If the previous step is not performed, a Diagnostic Trouble Code (DTC) will be set.
  9. If necessary, use a proper scan tool to erase any Diagnostic Trouble Codes (DTCs) from PCM.
