Erasing Fault Codes - Volvo Penta D4 Operator's Manual

Erasing fault codes

Any fault codes in the diagnostic function are automa-
tically erased every time the starter key is turned to
the stop position (S).
NOTE! Stop the engine and check that the ignition
key(s) is(are) in position 0 in all control positions.
When system voltage is switched on again, the diag-
nostic function checks to see whether there are any
faults in the EVC system. If this is the case, new fault
codes are set.
This means that:
1. Fault codes for malfunctions which have been at-
tended to or have disappeared are automatically
erased.
2. Fault codes for malfunctions which have not been
attended to must be acknowledged every time the
system voltage is switched on.
If the diagnostic button is pressed after all stored fault
codes have been erased, code 1.1 ("No fault") will be
flashed out.
