P1787 2-1 Downshift Error
P0700 Transmission Control System (MIL Request) Malfunction

Here is the deal, u have some serious transmission related faults, in order to sort this out u will need to take this to the dealer, allot of testing is required to get to the bottom of this, if I had to guess I would say the trans is going to have to be overhauled.

P0455 Evaporative Emission Control System Leak Detected (gross leak) - check your entire engine bay contents for any type of leak, air conditioner when it's running, coolant, things like that.

P1684 Battery Disconnected Within Last 50 Starts - this is a code that will go away over time

Something as simple as a different tire size can cause the abs to go nuts. I even had it where the two tires were the same size. But a different brand name. Each manufacture has their own tire sizing so not all tires a equal in size. Even though it says on the side of the tire that they are the same size.

Sometimes the cooper inside the insulation of the wires going to the sensors corrodes. Especially on the front units. It reads more ohms than normal but not open and is very intermittent. However moving the wires my make it work for a while. That's why replacing bearings seems to fix the problem but it comes back after a while.

You can test the speed sensors yourself...
Front sensor specs:
956 to 1240 ohms in 41 to 110 degree weather
at least 100mV AC (NOT DC!) volts when hub is spun by hand
Rear sensor specs:
950 to 1300 ohms in 41 to 110 degree weather
At least 100mV AC (NOT DC!) volts when hub is spun by hand

Here is some information from service bulletins that could be related to the problem. The traction control, antilock brakes, and tire inflation monitor all use wheel speed sensor input.

This first bulletin seems like it could be the problem because engine movement is involved:

GM Corporate Bulletin 00-06-04-049B
This Bulletin covers a problem that can cause multiple failures, one of which is an Antilock brake problem, and covers 2000-2003 Impala and Monte Carlo built prior to 2/03.
Check to make sure the wiring harness adjacent to the AC accumulator/dryer is not rubbing against the ac accumulator chaffing through the insulation of the wires in the harness.

GM Corporate Bulletin 03-05-25-008 overview:
GM front wheel speed sensor harness replacement - 2001-2003 Buick Century, Regal; 2001-2003 Chevrolet Impala, Monte Carlo; 2001-2002 Oldsmobile Intrigue; 2001-2004 Pontiac Grand Prix
This bulletin is about inspecting the harness going to the front wheel speed sensor for wear from contact with front suspension parts.
Repair harnesses/leads are available that can be spiced onto the main harness.

Hope helped.

COMBINATION FLASHER LOCATION The Turn Signal and Hazard Warning Flasher is combined into one unit called a Combination Flasher (Combo-Flasher) The combo-flasher controls the flashing of the hazard warning system and the turn signal system. An inoperative bulb or incomplete turn signal circuit will result in an increase in flasher speed.
The combo-flasher is mounted to the in-line bracket which is located to the right of the Junction Block. The flasher can be removed by pulling in an rearward direction. The left under panel silencer duct must be removed to access the flasher. The combo-flasher is black in color for ease of identification

Grab the bottom seat cushion at the front of one side and pull it straight up then do the same on the other side. (you will have to pull up very hard) The bottom of the seat clips in. once you have the bottom out take the 2 bolts out of the seat belt fasteners that holds the bottom of the top seat cushion. Then pull straight up on the seat cushion to slide it off two tabs that hold the top.

Hello Jim.
The thermostat is located at the inlet hose from the radiator on the front of the engine.
Here is a diagram of the housing.


There are two fuses for the cooling fan and two relays as the fans run on two different speeds.
These fuses are in the under hood power distribution box.
Fuse "E" and fuse "B" and the fuse for the relays is fuse# 21.


There you are as asked.

Is this P0605 and P0700? If so read on.
P0605 - Control Module Fault
Possible causes- ECM/PCM Harness power supply circuit is open or shorted
- ECM/PCM Harness ground supply circuit is open or shorted
- ECM/PCM may be faulty
P0700 CHRYSLER - Transaxle Control System (TCM) Malfunction
Possible causes- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module
Tech notes Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem
