SOURCE: 1999 Dodge Caravan posts trouble

The p1698 code is for the (bus) that is how the computers commmunicate with each other and also how the scan tool talks to the computers.

There is a common problem with these vans, that would be a good place to start. The battery will leak acid onto the wires underneath the battery. If you remove the battery and battery tray you will be able to see the large wiring harness under the battery. Inspect all of the wires underneath the battery for damage.

could be a bad pcm, but a shorted or open bus wire is also possible. this kind of diagnosis is very time consuming chasing wires and would best be done with a shop manual with wiring diagrams and flow charts

SOURCE: where is the PCM located on a 99 dodge durango?

The PCM is located on the fender well in the back of the engine compartment close to the firewall. It is a gray rectangle about 7" x 5". It is ribbed. It attaches using three screws.

It is also located close to heater core parts of your truck. If your overheating problem is related to the heater core, it may in fact be causing the PCM to everheat, though I've never heard of it happening before.

SOURCE: 2000 Dodge Caravan PCM replacement

2001 Dodge Caravan died warming up in the driveway last weekend. Turned the key and no engine cranking. Lights on the dash all lit and completed internal diagnostics normally. Keyless entry worked and the battery seemed OK. On closer inspection there was no clicking from the starter that would indicate a weak battery, nor were there any Diagnostic Trouble codes (DTC's) set by the computer (PCM) -I have a scan tool. Checked fuses and relays with volt meter in the realy center next to the PCM. By by following the schematic (using a Haynes manual) I was able to supply battery to the starter (the engine cranked just fine) and the fuel pump (it ran).

On further investigation I determined that the PCM was not supplying ground to the Automatic Shutdown Relay, or the Start relay. As the camshaft sensor and/or the crankshaft sensor can tell the PCM to shutdown, I repalced those two items on a long shot to no avail. Had the car towed to a shop I work with and they came to the same conclusion that I did -- the PCM needed replacement.

Called NAPA and they sold reconditioned units for about $170 (with core return) there was a nationwide backorder on them (Don't know why). Found an online outfit All Computer Resources, that had refurb units. The unit was more expensive, but they programmed the VIN and milage in before shipping. I had the unit overnighted to the shop. It arrived the next morning and I had my fingers crossed. The VIN determines the PIN for the passive security system (SKIS code). But, there were no problems. I picked the car up the next day. So far it's running just fine.

PS: if you pick a unit up from the junk yard you will have to get the VIN programmed in before it will run. It might start, but the security system will shut it down. Hope this helps someone.

SOURCE: I have a 2002 Dodge Durango & my PCM needs to

You may be able to get it replaced under warranty if it's less than 80,000 miles on the odometer.

To answer your other question, it all depends on how the PCM was blown. It may have shorted out just enough to cause a constant draw in the system. Maybe not noticeable right away, but weather changes etc. can cause the cumulative drain to be more than the battery is being charged while driving (if you're not putting a LOT of miles on when you drive it)

What does code p2096 mean for 2005 magnum SE?


P2096- Post Catalyst Fuel Trim Sys Too Lean Bank1... It could be the result of bad gas or if you used fuel with a higher content of Ethanol. It could also mean that the post cat. converter O2 sensor on the driver side is bad. I would try filling up with a good quality gas (minimal Ethanol content), disconnect the negative terminal on the battery for a minute or so to reset the MAL (malfunction indicator light) and see if that takes care of it. If the code reappears, you may have a bad sensor, maybe ECU ECM PCM, worst case.... If you happen to need any info or ECU ECM PCM for this current vehicle (as they have a HIGH failure rate) or ANY other type of Car, diesel trucks small and big, SUV DIESELs ANYTHING etc, please call 888-672-4816 or 954-279-2040 and tell them Tim From FIXYA.COM sent you for FREE PROGRAMMING on YOUR NEW ECU ECM PCM DIESEL OR GAS COMPUTER!!

these engine controllers are notorious to go bad. you probably need a new one or yours rebuilt. the 318 should be the 5.2l magnum engine if memory serves. the powertrain control module (pcm) is located on the firewall at the right-hand rear corner of the engine compartment. ill include images for ya. call me if you want this resolved. 800-921-9060 regards,

I own a 97 dodge dakota sport v8 magnum with a 318 its having problems holding a charge , i've replaced the alternator the belt and the battery , still won't hold a charge to the alternator


1997 DODGE DAKOTA CHARGING SYSTEM
OPERATION:
The amount of amperage produced by the alternator is controlled by the Electronic Voltage Regulator (EVR) circuitry within the Powertrain Control Module (PCM)
EVR circuitry is connected in series with the alternator field driver terminal and ground. A Battery Temperature Sensor (BTS), located in the battey tray under the battery, is used to sense battery temperature.
Sensed battery temperature and data from monitored line voltage is used by the PCM to adjust the battery charging rate. This is accomplished by cycling the ground path to control the strenght of the alternator magnetic field.
The PCM then compensates and regulates alternator amperage output accordingly.
If a problem is sensed in a monitored circuit, a Diagnostic Trouble Code (DTC) will be stored in PCM memory and the Malfunction Indicator Light (MIL) (commonly refered to as the "check engine light") will be illuminated, providing certain criteria have been met.
DTCs can be read using Chrysler's Diagnostic Readout Box (DRB-III) or a generic scan tool.
When diagnosing any problem concerning the charging system on this vehicle, it is recommended that you begin by scanning the PCM for fault codes in order to eliminate certain possibilities and provide a more accurate and timely diagnosis.
If you have any fault codes pertaining to your charging system, please post them in a reply on this page and I will be happy to guide you through the diagnosis process.

I have a 2000 Dodge Ram w/113,000 miles on it. Have started getting a "no bus" or "no bu 5"code on my odometer - plus my gauges have stopped working. Any clue?


The problem is related to the PCM (Powertrain Control Module) and "No Bus 5" means that the PCM is not communicating with a certain module, and it can cause the gauges and the warning lights to all malfunction and act erratic, and also cause a loss of engine performance.

It is also very possible that an after-market stereo could interfere with the operation of the PCM or any of the other control modules because those dodge systems are easily disrupted by electro-magnetic or radio frequency interference especially if it is right there next to them, and it has happened before. Also, the passenger side air-bag switch can get a fault in it that really wreaks havoc with the PCM and a dealership could tell you if the passenger side air-bag switch is faulty or not.

Try this,

Follow in Order

1. Dis-connect the battery.

2. Dis-connect the wiring connector on the PCM.

3. Re-connect the wiring connector to the PCM.

4. Re-connect the battery.

Start the vehicle and check to see if the gauges and the warning lights are acting normal again, and if they are then there is a problem with the PCM and it is most likely becoming faulty and will soon fail.

P 1684


Battery Disconnected Within Last 50 Starts
The PCM has lost power while the car is off. Your battery posts may be corroded or a battery wire may be losing it's connection. Inspect the cables and make sure they are secured and make sure the terminals are clean. Also a dying battery could trigger this as you draw a lot of power from it when you start the engine and this could get low enough to trip the PCM.

Electronic Throttle Control


DTC P2106 Throttle actuator control system-forced limited power DETECTION CONDITION
• The PCM monitors the throttle actuator control current when the ignition switch is on. If the control current is less than 8 A or more than 11 A, the PCM determines that the throttle actuator control system is under forced limited power. Diagnostic support note
• This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory. POSSIBLE CAUSE
• Throttle actuator malfunction • Connector or terminal malfunction • Open circuit in wiring harness between throttle body terminal A and PCM terminal 1B • Short to power supply in wiring harness between throttle body terminal A and PCM terminal 1B • Short to GND in wiring harness between throttle body terminal A and PCM terminal 1B • Open circuit in wiring harness between throttle body terminal B and PCM terminal 1C • Short to power supply in wiring harness between throttle body terminal B and PCM terminal 1C • Short to GND in wiring harness between throttle body terminal B and PCM terminal 1C • PCM malfunction
and for the other one

the dealers need to reflash the powertrain module ( ETC ) ...
