The diagnostic system box is located in the engine compartment,
behind the left-side strut tower:
1. Fault codes retrieval
- Open the diagnostic system’s box cover and place the test cable
mounted on the side of the box into an appropriate socket. - Turn the ignition ON to key position II without starting the
engine. Wait about ten seconds. - Press the button once and hold it for more than one but less
than three seconds. - 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. - Count the successive flashes and record the fault code.
- Press the button again, as described above.
- 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). - Turn the ignition OFF and remove the test cable from a
socket.
2. Erasing fault codes
- Repeat step 1 and read all the fault codes again. Do not
turn the ignition OFF after read-out. - Press and hold the button for more than five seconds, then
release it. - 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. - 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,
5 – (investigating),
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.
