I have been chasing codes and repairing the components that would
trigger a code.
The only code (other that 12) left is...
Problem: Code 83 - TCC PWN Solenoid Circuit Fault
Rough idle in neutral, almost dies when put into gear.
There is no terminal F wire present at the ALDL so I couldn’t check
for voltage there.
I checked the fuse for "Gages" and I see voltage across both
terminals with a DMM.
I checked the tan/black wire at the 20 pin connector at the passenger
side of the transmission and there was no voltage with the key in the
on position. There is supposed to be lettered markings on the male or
female end of the plug but I couldn’t see any indication of letters
molded into either side of the plug. I also cleaned the plug with
I went to check for 12 volts across the brake switch which is
described in a TCC test procedure. The procedure references one of two
possible brake switches, an upper switch with a vacuum hose and two
wires, or, according to the document, there is a lower switch with
four wires. The document is ambiguous as to whether one or both of
these systems are present on the van.
As I am poking around trying to find these components, (which I still
have to find) I put my hand on a solenoid that actuates a plunger that
has a cable attached to the end and two wires attached to the
solenoid, which is attached to the steering column. The solenoid gets
so hot when the key is "ON" that I could not leave my finger on the
solenoid for a half of one second before it burned my finger! It is
located on the steering column and actuates when the brake pedal is
depressed a small amount.
I am sure that this is a problem because any solenoid that gets that
hot has a problem. I do not know the name of this component to get a
Question #1 - What is the name of this component so I can tell the
parts store the correct name for them to look it up on their computer
Question #2 - What brake connections do I need to check for voltage
beyond the one listed above. I initially could not find a typical
brake switch which would be a plunger with two wires connected and
attached to the brake pedal directly. I can see where the typical
mounts for this type of switch would be located, but nothing is in the
Question #3 – Are there other circuits that need to be tested in the
I have asked this question on other forums, with no responses. I hope
that one of the readers of this post can assist me.
