2.8.3. Errors the ECU

The controllers equipped with a OBD adapter (STAG-4 QBOX/QNEXT PLUS / STAG-300 QMAX
PLUS) are capable of continuous monitoring of recorded and pending faults with the use of the
onboard OBD2/EOBD interface. The errors are displayed as codes according to OBD2/EOBD notation
system with descriptions.
If an error occurs, the "Delete" button can be used to erase OBD fault codes, which is equivalent to
error acknowledgement (check engine lamp) via an external OBD scanner.
"Auto clear list" button allows configuration and activation of automatic clearing of OBD2/EOBD errors.
The configuration window is split into two panels. The left one contains a list of all errors that can be
cleared. In order to activate the automatic clearing function, move the selected errors to the right panel

The controller detected a brief loss of the ignition
switched positive signal. Check if the ignition
positive wire is connected in the correct point.
Reversed connection of the emulation circuit of the
petrol injector with the indicated number. Detection
of a reversed connection is active only in the GAS
fueling mode. Channel indication is valid for
sequential control systems. With semi-sequential
control, channel indication refers to the pair, in
which one (or 2) emulator(-s) is (are) connected
incorrectly. If the full-group control is used, the
indication is not precise and channels should be
manually switched to petrol to identify incorrectly
connected emulator circuits.
The controller can "see" the impulses of petrol
injection, but does not "see" RPM signal.
