Error codes in greater detail

I tested for error codes on my '95 850 GLT and got 124 and 322. I need details about what needs to be done to fix this problem.
What does incorrect gear ratio mean?
What does mode selector faulty or short circuit to ground mean?
I WOULD APPRECIATE ANY INFO
Thanks, Phil

What port(s) were the codes from?

Thanks for the quick reply Lee. As you can see, I can't seem to do that. I got those codes when I put the jumper onto A2. Since then I have taken the PNP apart, cleaned the old grease out, filed and sanded the copper contacts (the one with the longest sweep was worn down on one end more than the other end),put it all back together. It worked for a couple of days, with the added benefit of the reversing lights working since forever. But the arrow started blinking again and it was back in limp home mode.I jumped A2 for the codes again and 322 came up. I cleared the code and it worked for about three or four startup and stops. This time the blinking arrow came on as I was cruising down the freeway at 65 MPH. The writeup I followed had you putting vicks vaporub all over the contacts in the PNP, so I figured the better stuff to use was dielectric grease. Could I have use too much and it shorted across the contacts? This is an 95 850 GLT

It sounds like you have issues with the transmission. Those codes are read in port A-1. Port A-2 reports engine codes. Code 3-2-2 is a MAF code.

Lee, you are absolutely right. I was writing yesterdays ditty just from memory (Mine's pretty bad),when I actually looked at the paper where I wrote the codes on -actually said A1- so we're back to the transmission. I still worry about too much dielectric grease in there. Getting back to the original questions: What does incorrect gear ratio mean? and I tested the mode selector and it ohms ok but the"short circuit to ground" I couldn't figure out. the wire colors were wrong when I disconnected the TCM. why don't they use pin numbers or positions. Anyway I couldn't do the tests for #3 on page 27 of the march 9 2010 answer to"1994 No start. no spark" by confused al.

Here's text from Vida regarding the transmission codes...

DTC information 1-2-4
The driving mode selector allows the driver to select from three modes: Winter (W), Economy (E) and Sport (S). The mode selector has two signal wires, MS1 and MS2, and a ground wire. The choice between W, E and S modes is made through the connection of either one or the other, or both signal wires to ground (the signal goes low). Note that MS1 and MS2 signal wires are grounded simultaneously only when the W button is depressed.
If the TCM registers that the signal is low (low voltage) in both signal wires simultaneously for at least 30 seconds, the DTC 1-2-4 is set.
Note! It follows that this DTC can be set if the W button is depressed for more than 30 seconds.

Substitute value
The transmission will only operate in driving mode Economy (E).
Possible source
Short circuit to ground in the signal wiring
The W button has been depressed for more than 30 seconds.
Defective mode selector.

Fault symptom
The gear box operates in driving mode E regardless of the position selected on the driving mode selector.

DTC information3-2-2
The control module calculates the ratio between the transmission input rpm and the car speed. There is a specific ratio for each gear. If the TCM registers a ratio deviation of more than 10%, the DTC 3-2-2 is set.

Possible source
Interference with or signal errors on the signal from the transmission rpm sensor
Interference with or signal errors on the signal from the vehicle speed VS signal from the combined instrument
Contact resistance in the Solenoid S1 or S2 circuit.
Gear position sensor incorrectly adjusted
Malfunction in gear position sensor
Transmission oil level too low.
Mechanical fault in the transmission. Worn componenents in the transmission causing slippage or reduced system pressure.

Fault symptom
Poor performance due to the transmission operating only in 4th gear
A noise or some obvious mechanical fault is the most common indication of a mechanical fault in the transmission.
