SD 812a en Page 2 of 203 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 This SD supersedes SD 812- 08.2001 © 2006 MAN Nutzfahrzeuge Aktiengesellschaft VAST, mr 02.2006
