Why is my Dodge Ram 1500 no start?

Please try again later. This 2004 4.7l Dodge Ram 1500 had an intermittant no crank/no start. Instrument cluster self test revealed no communication with the PCM. Wiggling the wires at the Integrated power module and PCM seemed to help but eventually it refused to crank at all. Problem was traced back to a worn through PCM B+ wire.

What does no start no crank no click mean?

If you have a late model GM vehicle and turn the key only to hear nothing, you’ll most likely think you have a dead battery—and you may. But a no start, no crank, no click condition can be far more involved than that. In the old days, power flowed through the ignition switch and down to the starter solenoid. Not anymore.

What causes a car to have a no start condition?

The battery or battery problems are the number-one cause of this type of no-start condition. A quick way to check your battery is to turn your headlights on. If the headlights come on and are nice and bright, not dim or dull, then it’s likely your battery and its connections are okay.

Where is the no bus signal on the Odom?

The no bus signal on the odom. Pcm depends on an 8 volt ref to communicate through the bus line to the cluster to operate the dash and to communicate threw the aldl connecter.

What causes a PCM to fail in a car?

PCMs are rated to last far, far longer than any of your car’s sensors, so their failure is usually caused by other issues in your car’s electrical system, such as power surges. If you don’t want to find yourself back in the shop three months later replacing your PCM again, ask your mechanic to find out why it failed to begin with.

Is the no bus on the odometer a problem?

2001 Dakota quad cab 3.9. Same problem. No bus on odometer. Scan tool cannot communicate with PCM. Check 5v ref on crankshaft, MAF, TPS and camshaft sensors. All good none grounding out.

What do I do if my gas gauge is not working?

In most cases, to gain access to the fuel tank sending unit mount / fuel pump mounting hole, you’ll need to drop the gas tank down. Be sure to do this when there is either minimal gas in the vehicle, or it’s been siphoned out.

What does the gas gauge read when the tank is empty?

Most older sending units are a “0-30” or “0-60” ohm sending unit, meaning that when the tank is at empty, the resistance will read 0ohms, where at full, it will read 30, or 60ohms. To test this, simply put your mutl-meter to ohms (resistance) setting, and touch off one probe to the sending terminal, and the other probe to ground.

Why does my Dodge Ram say no bus?

Had a “no bus” on both my ’99 ram, and ’01 Durango. Both were bad ECM’s. That bolt just holds the plug into it’s socket. It doesn’t actually have anything to do with the connection. Pull the plug and clean it with electrical cleaner. Inspect the wiring harness for breaks. If it looks good, plug it back in and see what happens…

Why is my odometer blinking at 5, 400 miles?

Bringing back an old thread because this just happened to me. My odometer started blinking today at about 5,400 miles. No oil change message, no other lights/symbols. My car, stereo, and cluster are stock. No apparent reason for the blinking. I disconnected the negative battery terminal for a minute then re-connected.

What should I do if my gauges are not working?

The first step in diagnosing this type of issue is to identify the fuse associated with the instrument cluster or gauges. The fuse should have power on both sides when the ignition key is turned to the on position.

What does it mean when your speedometer is not working?

If the oil pressure, coolant, charge, or gas gauge doesn’t work or works erratically, the problem is in the gauge, wiring, or sender. Speedometers are unique in that some of them use physical cables instead of sensors, so a speedometer not working can also indicate a broken cable or stripped gear.

What is the baud rate of the CCD data bus?

The CCD data bus system was designed to run at a 7812.5 baud rate (or 7812.5 bits per second). In order to successfully transmit and receive binary messages over the CCD data bus, the system requires the following:

When does the CCD system go into idle mode?

When the data bus voltage differential is a steady 0.02 volts, the CCD system is considered “idle.” When no input is received from any module and the ignition switch is in the Off position for a pre-programmed length of time, the bus data becomes inactive or enters the ”sleep mode.”

What does collision mean in a CCD system?

Within the context of the CCD system, the term “collision“ refers to the system’s ability to avoid collisions of the electronic data that enters the data bus from various electronic control modules at approximately the same time. Multiplexing is a system that enables the transmission of several messages over a single channel or circuit.

How are binary messages transmitted on the CCD data bus?

The “D” in D1 and D2 identify these as diagnostic circuits. Transmission and receipt of binary messages on the CCD data bus are accomplished by cycling the voltage differential between the Bus (+) and Bus (–) circuits.

What does it mean when your car says no bus?

Rate this answer: The “no bus” signal is indicating that there is no fuse, a blown fuse, or no power the the ECM (electronic control module or “the brain”) make sure all relays are operational as well and you should be on your way.

Why is my no bus odometer not working?

This ‘bus’ is the 2 wire communication network that all the computers share information on. Your instrument cluster isn’t gettin any info over the bus that’s why you get the ‘no bus’ message and none of your gauges work. This can be caused by any shorted module or broken bus wire. A few PCM sensors can cause this problem too.

Why does my Dodge Ram not have an odometer?

If all that checks out unplug the following sensors: Cranks sensor, Cam/SYNC sensor, TPS, MAP and Trans connector. These 5v sensors can short out the CCD bus because they share the same power source. You will have to cycle the key off and on to reset the PCM and CCD bus once you find the problem.

What does no bus mean on a computer?

Any computer, wiring, or connections can cause this. You need a scan tool to diagnose. “no bus” means the PCM (computer or module) is not able to communicate. Could be something as simple as a fuse (.50) or as complicated as a bad PCM ($1000.00) “NO BUS” means that the communication system between the computers has stopped working.

How does no bus work on a Dodge Durango?

Where does the fault code go on the odometer?

If a fault code is present, the cluster will display it in the odometer display. When all fault codes have been displayed, the cluster will display “end” or “E” for end in the odometer display.

What causes the No Bus message on the odometer?

Symptom: Engine will not start. Gauges are inoperative. “No BUS” message displayed on odometer. Problem 1 of 2: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Crankshaft Position (CKP) Sensor.

Why are all of my gauges not registering?

The sending unit wire could be bad or broken, or the circuit from the gauge to the sender is incomplete. Without a ground, the gauge will not register. It is highly unlikely that all the sender units are bad, so we can rule that out. Of course, it is also possible that all the gauges are malfunctioning.

What does it mean when your gauges are not working?

With all the gauges not working, look first for a loose ground or power interruption.a single gauge would mean just that circuit had a circuit or connection issue. Hope this helps. Thanks again for your help. Turns out it was just a fuse. Replaced it and it all works again…

What to do when the gauges stop working in a Buick Regal?

Another method is to disengage the battery terminals and then manually keep momentarily touching them to the battery, as sometimes this helps for the needles to return to where they should. What could be the problem in a 2004 Buick Regal where the resistors were replaced after which all the gauges stopped working?
