QuestionQUESTION: I have a 2000 Chrysler Grand Voyager with the 3.3 Flex Fuel engine, I'm not sure what 4 speed transmission.
My van went into limp-in mode while driving the other day and the service engine light came on. I took it to an auto parts store to have the codes scanned, it gave 2 codes:
2/4 solenoid circuit fault.
Transaxle control system fault.
The parts guy said the second code was probably a result of the first code.
I checked the wiring harness connector to the solenoid assy, the one that has a bolt through the center, when I pulled it off, there was transmission fluid inside the connector where the pins connect to the plug. Is that normal? Also, I researched some previous answers that you gave for the same error code, and in one you gave resistances of the solenoids and pressure switches. Do you have a diagram of the connector so I can meter them?
Also, the fuse to the anti lock brakes blew a couple of days before this happened. Could there be some kind if connection? I haven't replaced it yet, I have to go buy some, so I don't know if it will blow again.
Thank you so much for your time,
Mike
ANSWER: Hi Mike,
On the fuse question, you didn't say which of the 3 fuses that power the abs blew. Fuses 12 and 25 under the hood are for the abs exclusively, while fuse 12 under the dash also serves the transmission range sensor and many other devices not related to the abs or the trans.
I can send you two pages from the wiring diagrams that show the connections between the solenoid assembly and the TCM. I don't have the '00 manual, but the '98 and '02 that I do have are identical except for one colored voltage supply wire, but the pins are the same. Let me know a postal mailing address and I'll xerox and mail them.
I can't be certain about the fluid/connector question but those solenoids/switches are handling high pressure fluids so some leakage might not be unreasonable to find.

QUESTION: I don't know which fuse# it is, but it's the 25 amp fuse under the hood labeled ABS SYS. I got a new one today, when I put it in I noticed a flash coming from under the fuse module. I thought it blew the fuse again, but it didn't. There wasn't a flash the second time I put it in. The ABS warning light does not stay on now. I pulled the fuse module back, but I can't find any obvious burned wires. I even pulled out all the connectors from the bottom of the fuse module, but found nothing amiss.
By the way, is that the ECM next to the fuse module? Where is the TCM located?
Thanks,
Mike
ANSWER: Hi Mike,
That fuse is #12 and it may have been a trasient draw when you put in the fuse powering up some aspect of the ABS control module. If the light is off then it should function. Yes the ecm is next to the fuse module, and the tcm is on the opposite side of the engine compartment, roughly a mirror image. If you don't see it there, then my '98 manual doesn't apply, in which case the tcm is on the transmission proper just above the solenoid box ('02 manual). Please let me know where you find it to be so I will know which of my manuals applies to the '00 model that you have.

QUESTION: Roland,
The tcm module is opposite the ecm. The 2000 model is the last year for that body style, so probably everything from you 1998 manual should apply.
IS it bad to drive the van in limp-in mode if I drive slowly to not over tach the engine, or could I do damage to the transmission? This is my only vehicle.
Thanks,
Mike
AnswerHi Mike,
Limp mode uses the fewest parts and is a fail-safe mode. The only concern would be prolonged high rpm might raise the temp of the trans fluid which can increase wear/break down of fluid. So check for whether fluid smells burned.
Thanks for the location info. The wiring diagrams will go in the mail this morning.
