code reader info

Post by doingitsideways » Sat Apr 19, 2014 11:06 am

Hi,

I can't seem to find the thread with all the meanings of fault codes anywhere.

Can someone please post me a link?

Trying to figure out why my new (Jamesy12345's old) Turbo won't idle.

I have MANY codes to look up! :(

Thanks,

Edit:

Think I've found what I need after a bit of digging.

Seems I have many ABS faults, but none on the fuel ECU...

Bizarre.

Ah, the joys of 480 ownership! ;)

Fault Codes Retrieval

1. Open the diagnostic system's box cover and place the test cable mounted on the side of the box into an appropriate socket.
2. Turn the ignition ON to key position II without starting the engine. Wait about ten seconds.
3. Press the button once and hold it for more than one but less than three seconds.
4. The LED lamp will flash in successive series of three digits followed by a three-second pause. If there are no fault codes stored, it will flash 1-1-1 indicating the system being tested is operating correctly.
5. Count the successive flashes and record the fault code.
6. Press the button again, as described above.
7. Record the fault code. If it is the same as the previous one, then no additional codes are stored. Repeat until all the codes stored are retrieved (often a maximum of three).
8. Turn the ignition OFF and remove the test cable from a socket.

Erasing Fault Codes

1. Repeat step 1 and read all the fault codes again. Do not turn the ignition OFF after read-out.
2. Press and hold the button for more than five seconds, then release it.
3. When the LED lights, press the button again for more than five seconds and release it. When the LED goes off, the memory is cleared.
4. Test that memory is cleared by performing step 1. Code 1-1-1 should be returned.
Note: erasing fault codes on the ABS socket will cause the ABS control to be lit. It will turn off after a test-drive with speed of more than 40 km/h.

Sockets Description

1 – alarm and remote locking system,
2 – fuel system,
3 – ABS,
6 – cruise control,
7 – SRS (airbag).

Hints

Before assuming a fault in any of the systems tested, try to erase fault codes as described above. In my case, open circuit in ABS wiring has initially been signalled with codes 122, 152, 312 and 322. After erasing and performing a test-drive, only code 312 was signalled.

At first, read the codes when the engine is completely cold. Then, go for a longer test-drive and read them all again while the engine is still hot. Some codes (especially these related to lambda-sensor) tend to appear only while the vehicle is driven and short time afterwards.

Any ideas why I cannot get the error code thing to work ?


I can get the error code reader to work on the old one EVA, no codes signalled (ie 1 1 1)

on NORA the LED doesn't light up when turn on ignition (old one it comes on then goes off after short time similar to time taken for fuel pump is primed?)


note that I can see a 'glimmer' of light from the LED depending if plugged into another socket so it proves that the LED does function AND the lead is intact.

to encourage my laziness , can the whole module be unplugged from the loom at the wheel arch or is 'part of the loom'

then I could swap modules from EVA to NORA , but maybe it is only a 'terminal block' with a push button?

Edit
so the module DOES unplug from the loom :-)

mine has ONLY pins 2, 3, 5 , 7 NOT 6 i don't have cruise or remote locking on either car

the button was crsuted up on NORA, but a quick dismantle and all is good, well the module is now on EVA.

a few extra hints regarding the code reader.
when the cable is plugged in initially the LED lights at half brightness
ignition to position 2 and LED goes out
when press button the LED illuminates (if it doesn't assume button pegged)
after code is read the LED stays off until ignition has been off for about 6 - 8 seconds, the same reset time as the fuel pump?

and NO error codes on the fuel system
