How to Solve CG FC200 Failed to Open Device

Problem:

I just received one new CG FC200 ECU programmer last week. After installing the FC200 software, I started to run the software, but I encountered three errors.

Error 1: e126: Failed to open the device, please check the device connection

Error 2: Failed to connect to the server. Check the network or try again later

Error 3: There is no authorization information displayed on the screen.

Cnautotool.com technician replied:

For error 1, the possible cause is that the device is not detected out.

Suggestion: Try on other USB ports

For error 2& error 3, please check if the network has been connected normally. Then go to try again.

How to choose the best OBD2 scanner

Buying an OBD2 Scanner might be a confusing process if you have no idea which scanner to choose. The OBD scanner in your automobile should be able to execute the following 11 critical functions. To summarize, it is better to buy an OBD scanner if it offers these 11 unique features.

Oil Reset Service

This function can be performed in the following cases:

1. If the service lamp is on, you must provide service for the car. After service, you need to reset the driving mileage or driving time so that the service lamp turns off and the system enables the new service cycle.
2. After changing engine oil or electric appliances that monitor oil life, you need to reset the service lamp.

Steering Angle Calibration

1. To reset the steering angle, first find the relative zero point position for the car to drive in a straight line. Taking this position as reference, the ECU can calculate the accurate angle for left and right steering.
2. After replacing the steering angle position sensor, replacing steering mechanical parts (such as steering gearbox, steering column, end tie rod, steering knuckle), performing four-wheel alignment, or recovering the car body, you must reset the steering angle.

Electronic Parking Brake Reset

If the brake pad wears the brake pad sense line, the brake pad sense lines ends a signal sense line to the on-board computer to replace the brake pad. After replacing the brake pad, you must reset the brake pad. Otherwise, the car alarms.

Reset must be performed in the following cases:

1. The brake pad and brake pad wear sensor are replaced.
2. The brake pad indicator lamp is on.
3. The brake pad sensor circuit is short, which is recovered.
4. The servo motor is replaced.

ABS Bleeding

This function allows you to perform various bi-directional tests to check the operating conditions of Antilock Braking System (ABS).

1. When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system to restore ABS brake sensitivity.
2. If the ABS computer, ABS pump, brake master cylinder, brake cylinder, brake line, or brake fluid is replaced, the ABS bleeding function must be performed to bleed the ABS.

Electronic Throttle Position Reset / Learn

This function enables you to initialize the throttle actuators so that the “learned” values stored on ECU are returned to the default state. Doing so can accurately regulate throttle (or idle engine) operations to control the amount of air intake. Throttle matching must be performed in the following cases:

1. The ECU is replaced and the ECU does not yet store throttle working features.
2. The ECU is disconnected from power and the ECU memory is lost.
3. The throttle assembly is replaced.
4. The intake pipe is replaced or removed, which affects idle speed control by ECU and throttle body.
5. The throttle is cleaned. Although the idle throttle potentiometer features remain unchanged, with the same throttle opening, the air inflow has changed and idle speed control features have changed.

Battery Register/Battery Maintenance

This function enables you to perform a resetting operation on the monitoring unit of vehicle battery, in which the original low battery fault information will be cleared and battery matching will be done. Battery matching must be performed in the following cases:

1. Main battery is replaced. Battery matching must be performed to clear original low battery information and prevent the related control module from detecting false information. If the related control module detects false information, it will invalidate some electric auxiliary functions, such as automatic start & stop function, sunroof without one-key trigger function, power window without automatic function.
2. Battery monitoring sensor. Battery matching is performed to re-match the control module and motoring sensor to detect battery power usage more accurately, which can avoid an error message displaying on the instrument panel.

Diesel Particulate Filter (DPF) Regeneration

DPF regeneration is used to clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode (such as high temperature heating combustion, fuel additive or catalyst reduce PM ignition combustion) to stabilize the filter performance.

DPF regeneration may be performed in the following cases:

1. The exhaust back pressure sensor is replaced.
2. The PM trap is removed or replaced.
3. The fuel additive nozzle is removed or replaced.
4. The catalytic oxidizer is removed or replaced.
5. The DPF regeneration MIL is on and maintenance is performed.
6. The DPF regeneration control module is rep
7. Tire Pressure Monitor System Reset

TPMS Tire Pressure Monitoring System Reset

Makes tpms sensor in displaying sensor IDs from the vehicle’s ECU, inputting TPMS sensor replacement IDs and activate TPMS sensors.

Immobilizer

This function can protect your car from being stolen by clearing the lost car key information and programming new key into the ECU database. Also known as keys programming.

How to use PIWIS III Code Porsche 991.2

Car model and year: Porsche 991.2 with PCM4.0 without the Bose amp.

Symptom:

Deleted my PCM head unit. The downside is that the OEM shelf isn’t tilted enough, under hard acceleration your phones/keys/whatever you put in there will fly out…

Problem though, is that the bootup sequence of the car has a certain PCM check in it. Without the head unit, once the key is inserted and the lock barrel turned, the following “System Fault” message shows up:

Porsche 991.2 coding tool to use:

Get access to a PIWIS 3

Professional technician suggestion:

I just took a quick look, here’s how I did it when my radio was out.

From component overview list, select Gateway -> Maintenance Repairs tab -> Actual/Specified Configuration menu -> Confirm PCM is displayed with a red minus sign under “actual installation” -> Accept (F8)
Back to component overview
Select Instrument Cluster -> Manual Coding -> Next -> Uncheck PCM related options -> Accept -> *Take screen shot of old and new values at confirmation screen*
That should take care of the message in your cluster. You probably will have to clear stored faults too.

PIWIS may change some unrelated configuration parameters in your cluster, which is why I suspect you’re seeing some weird errors from your dealer’s attempts to fix this. If this happens, you need to put your PIWIS in engineering mode and correct the parameters individually using the screenshot of changed values.

If you plan on selling your PCM4, you can’t un-pair your VIN from the head unit like in previous versions. If you sell your PCM, the new owner will need to deactivate component protection at a Porsche Dealership (or anywhere with a PPN login and PIWIS III).

Finally! Solved!

Update: got it done just like–“Accepted the actual vs. specified config in the Maintenance Repairs tab and instantly dash error was gone, thanks!!

A couple discoveries along the way:
1. PADM error message is unrelated. In Actual Values there’s no current flowing to the left dynamic engine mount. A bit of searching here suggests I’m not the only one with a problematic dynamic mount. One for warranty.

2. Chalk the oil fill level message to an oversensitive sensor. Following a weekend of aggressive pulls and really running the car (must’ve burned some oil in the process) an “electronic dipstick” check cleared the dash before I even started on PIWIS.

3. While in PIWIS I was naturally curious and pulled the vehicle analysis log (“VAL”). Interesting bits: one can definitely log overrevs just by hitting the rev limiter! I logged double-digit ignition counts in Range 1 and 2. Doesn’t concern me one bit, my RS ain’t “auction material” in this or the next life. Mechanically, in Carrera Cup the same blocks regularly see 9k+ in downshifts (against an 8.8k redline and 100hr rebuild intervals) ditto 9.4k+ on the GT3R. But those looking to maintain a sterling DME should be aware!

4. Apparently there are different “authorization” levels of PIWIS. You heard it right, not all PIWIS are licensed the same. After solving my dash error at home, I showed my process to friends at the sole official dealer in Hong Kong. Really not to throw shade at their failed attempt, but to share with them what I learned. They went “whoa we don’t get these screens in our system, probably because of the different certificate levels given to us by the factory…” Both of us were floored to say the least, knowing how much the factory charges for their official PIWIS subscriptions!!
