Check the battery terminals and posts are shiny clean and tight. Have a load test done on the battery to check for a cell bridge failure.

Most likely the problem you are experiencing with the park assist is a fault in one of the sensors mounted in the rear bumper. I would not consider it to be a major fix, however there will be a few hours labor involved as the bumper cover needs to be removed to replace the sensors.

SOURCE: 2003 Lincoln LS V8, Won't turn over after errors

Forget the four coils. That is a common problem,but I would question 4 failing.
The ABS ,Parking Brake,Speedo Etc,where nothing to worry about,you were loosing power, when it went to fail safe,so they came up.

ETC -is Electronic Throttle Control, your problem? Maybe
You will need to have a scanner put on it's,daignostic connector under the dash,to check for codes. Them only a trained technician can follow a chart or test proceedure to properly repair.
I have a 2004 LS,one of Ford most high tech and complicated vehicles.
Conclusion: only a professional can repair you car.
I would start with a local shop. If money you have money to throw away,go to a dealer.
Most likely have to wave to it on a flat bed carrier. Don't flat tow it.

Loss of communication with the tcm and pcm


The onboard computer, or Powertrain Control Module (PCM),is the brains of the engine control system, so when the brain is not functioning correctly neither is the engine or anything else that the microprocessor controls - which may include the charging system, transmission, various emission controls and communications with other onboard control modules. Once a diagnosis has been made (and we emphasize the word diagnosis), then and only then should the PCM be replaced.
P0600....Serial Communication Link

P0601....Internal Control Module Memory Check Sum Error

P0602....Control Module Programming Error

P0603....Internal Control Module Keep Alive Memory (KAM) Error

P0604....Internal Control Module Random Access Memory (RAM) Error

P0605....Internal Control Module Read Only Memory (ROM) Error

P0606....ECM/PCM Processor

P0607....Control Module Performance

P0608....Control Module VSS Output 'A'

P0609....Control Module VSS Output 'B'

P0610....Control Module Vehicle Options Error

If you see any of these codes when diagnosing the vehicle with a code reader or scan tool, it may mean the PCM has failed and must be replaced. Additional diagnostic tests will usually be necessary to confirm the problem is really the powertrain control module and NOT something else. Refer to the OEM diagnostic charts for what these tests are. Usually it involves checking certain inputs to the PCM to see if it outputs the correct response. No response or an incorrect response usually means the PCM is defective and needs to be replaced.
All too often, technicians tend to blame that which they understand least. If an engine is not running right and the cause is not obvious, they may blame the computer. Throwing parts at a problem in an attempt to solve it may be good for the parts business, but when a customer brings a PCM back because it failed to fix their problem, nobody wins. Warranty returns on complicated and expensive components like powertrain control modules are an ongoing problem that costs everyone money.
UNNECESSARY POWERTRAIN CONTROL MODULE RETURNS. Over 50 percent of PCMs that are returned under warranty (either because the PCM failed to fix a performance problem or because the engine did not run properly after it was installed) have nothing wrong with them! So it is obvious a lot of people are swapping computers to see if a different PCM will fix their problem.
The trouble with returns is if the PCM has been on the car, you have no way of knowing if it is still "good" or not. Somebody may have crossed up some wires, zapped the PCM with too much voltage or who knows what? The computer needs to be tested and verified before it can go back on the shelf and be sold to somebody else.
Unfortunately, there is no easy way of doing that in a parts store. The PCM has to be hooked up to a sophisticated simulator that exercises all of the computer's input and output circuits to make sure it works correctly - which means the PCM has to go back to the supplier, be retested, and if no fault is found, repackaged and put back into stock.
Be warned, though, that many parts stores have a policy of "no returns or refunds on electronic components."

Code U3FFF


U codes are communication faults between the different modules present on your vehicle. The PCM has to maintain control via separate modules that monitor and control every aspect of it, from engine and emission control,transmission control, anti-lock, traction control, lighting, hvac, suspension control, etc...To diagnose these codes requires a quality scan tool and a technician who is experienced with these systems.

OVERDRIVE STUCK AND BARELY MOVES IN DRIVE.1 AND 2 GEAR WORKS OK


When the OD light flashes in this model it means that the Transmission control module (TCM) has detected a fault in the operation of the transmission. What needs to be done now is to have the TCM scanned for fault codes by a ****** repair shop and then they can make a preliminary diagnose of the problem and the cost to repair. In my opinion you have a failed transmission and it will need an overhaul or an exchange tranmssion.

Air Intake leaks located after the MAF sensor assembly MAF sensor signal circuit is open, shorted to ground or power MAF sensor has failed PCM has failed


Trouble Code: P1605

A/T Diagnosis Communication Line Malfunction

Possible Causes:


TCM communication line circuit is open or shorted to ground TCM communication line circuit shorted to VREF or power (B+) TCM or PCM has failed TSB 01-004 (01/01) contains information related to this code
For the P0100, check the connector on top of the MAF sesnor for looseness or corrosion. Connector is on top in piocture below. jturcotte_361.jpg

Check engine light is on with code p1698 what is this code


The code P1698 is: No CCD messages from TCM. That means the communication between the Transmission Control Module and the Power Control Module is lost. Sometimes this happens when a PCM, or TCM is replaced without being flashed, a bad connection at the PCM, TCM, or a bad TCM. Hope this helps.

Electronic power steering


It could be the electronic power steeirng module . With the gauges dropping out like that , the module could be bring down the data bus . Don't know how much you know about automotive electronic's an how the insturment cluster know's what speed to set speedo at an how full fuel gauge is an rpm on the tach .
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM calculates the vehicle speed based on the class 2 message indicating the wheel reference speed from the electronic brake control module (EBCM) if:
• The ECM/PCM detects a malfunction in the vehicle speed sensor circuit.
• The IPC detects a loss of class 2 communications with the ECM/PCM.
The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of class 2 communications with both the ECM/PCM.

012 GM Class II Communications

Checking the vehicle modules for DTC'S - diagnostic trouble codes is the first place to start .
The Power Steering Control Module (PSCM) receives a class 2 vehicle speed message from the Engine Control Module (ECM) via a class 2 serial data circuit. The PSCM uses this vehicle speed message, and other inputs, to determine the desired amount of steering assist.

DTC C0475
DTC C0476
DTC C0545
DTC C0847
DTC C0848

DTC C0900

your best bet ,take it to a qualified GM repair shop .
