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.

ZR8 OBD2 Code Reader with Live Data

Because there aren't any codes like you have there $7e8 ,where did you pull this from ? What year , make and model vehicle .

Check for a blown fuse, some times the OB2 port shares the fuse like cigar lighter ,etc
press the helpful button

Poss no power at OBD2 connector. Try another reader or new cable. Check pin connections

could be a blown fuse for the engine computer, or a problem with the key switch. you might check the cig lighter fuse too.

check your fuses, the purple wire on the obd2 plug in should test 12v

I have a 2003 new beetle TDI. I have got error codes on my ECM that have stopped my engine from starting. I got an OBD2 reader from the auto parts store. I plugged it into the OBD2 port below the steering wheel and got the error codes. After writing them down, I cleared the codes. the car started fine. It has pulled this a couple times over three years. I carry an OBD2 reader with me so I can clear the codes and get going again. Good Luck
