Diesel truck
what is this P5002 thing, no scan too shows that for OBD2.
all have letter code, like B5002 or U5002 etc.
Pnnnn is power train codes.
is this a USA car? gen 6? FUSO
it is a top 8 ton heavy truck, and not sold here.
now called a FUSO truck 2003 to present.
all the OBD2 reader is failing, so that means DC power is failing
most the time.
signal fails means ECU stopped sending data to the tool. 4D34 is listed as direct injection turbo, correct?
step 1, stalls. and lost comms.
the battery for weak (load tested) and make sure alternator /gen is working or computers on board will go off line and dummy up.
lost comms
all fuses checked good.
P228C, it has applied exclusively to diesel powered vehicles. It has also meant that the powertrain control module (PCM) had detected a low voltage signal from the control circuit of the electronic fuel pressure regulator, which reflected insufficient fuel pressure.
To start with, the lights do not have to stay on to get code readings. If fault codes are stored, they will be there with or without the lights being on. Your computer network should be scanned with the proper equipment that is designed specifically to interface with your Volks Wagen. Please note that generic OBD code readers CANNOT do this. Volks Wagen is like a whole breed of its own. You must have a scanner with VEHICLE SPECIFIC software to work with these. (I personally own an $11,000 Snap-On Wireless Verus that will not interface properly with a Volks Wagen for many functions.)
From your description, it sounds like you either have a charging system problem or you have an engine idle control problem. It is hard to tell you without checking the vehicle in person.
hello
Sounds like you might have a fuel problem. Most big name auto stores will hook up there OBD readers to your car for free. They do this in hopes that you'll purchase the part from them. The reader will give you the error code for the service engine light. This might give you more information and maybe lead you to the cause of the problem. It might just be as simple as a plugged fuel filter. Hope this helps
This is an electrical problem, I had this last winter where the car was restarting or the starter was not disengaging. The problem was with the starter. the contacts that meet the plunger in the starter were grooved severely and binded with the contacts.
I had to replace the contacts inside the starter.
Got a service engine soon light illuminated on the instrument panel? If so, look for codes related to the torque converter clutch. Sounds like a bad TCC Solenoid or problem within that circuit. If the torque converter clutch does not release in lower gear ranges then it's just like letting the clutch pedal out on a manual transmission - there is a direct lock-up between the transmission and engine and thus the engine dies.
Check for any stored codes, on 97 models you may have to turn on the key without starting the engine, do this 5 times in rapid order then stop with the key in the on position without starting the car.
The service engine soon light will blink
Count the number of blinks
This will be the begining of the code test and the actual code numbers and finally a code number stating the test is over.
Look up the codes in the haynes repair manual and it will lead you in the right direction for any parts that have thrown an error code.
I think you are going to have to pull the engine error codes to start the diagnostics. Do you know the key trick? With the engine off, put in your key and turn it until the dash lights come on, but the engine doesn't come on. Do this three times in a row and leave the key forward the last time. The odometer will now change and either display the error code, or say "Done" if there are none. Once you have the code, google-it and see what you get. You could be looking at an ignition, throttle-body, or injector issue. Hopefully the error code will start you down the right path.
