Fault Codes
of Volvo Industrial Engine
WARNING! Read the safety
instructions for handling and service in chapter “Safety information” before
starting work.
NOTE: Reading the fault codes
below, such as Code 2.1, PID /SPN 97, where 2.1 is a flash code indicated by a
flashing diagnostic lamp. PID / SPN 97 is read with the VODIA diagnostic tool.
When using DCU or DU, the fault code is displayed as plain text.
For a further explanation, see
“Reading fault codes”.
