For notes on setting or repairing the individual systems
please see the repair manuals or the relevant Service Infor-
mation sheets.
After completing repairs delete the fault memory.
The last page folds out; on the inside you will find the FMI
code and its meaning.
The SPN for the door module – driver's and co-driver's side
– can be read out only with MAN-cats II; the SPN is not
shown in the display.
If one SPN refers to the same fault/component in several
control units/systems, only the generic term of the system is
given.
Example: "03512 EBS OBD, request, red warning lamp for
diagnosis": this SPN applies to all EBS variants although
they are not all expressly named (EBS2, EBS5 etc.)
Ifo ne SPN refers to different fauls/components in several
control units/systems each relevant variant is named.
Example: 03099 EDC (Common Rail) fuel pressure sensor –
rail pressure
03099 EDC (no Common Rail) fuel pressure sensor
