This Service Manual describes the new common rail system installed on the E13C engine of large Hino trucks. The big-
gest difference compared with conventional common rail systems is that it uses an injector with a QR code. The basic
construction and operation of the system is about the same as for systems installed on the P11C engine, so this Service
Manual will only give a general outline of the E13C system and describe its unique features. For details on the common
rail system, refer to Service Bulletin ECD 01-08 "New Common Rail System (ECD-U2) for HINO" published in December
2001, and Service Manual "Common Rail System for HINO J05D/J08E Type Engine" published in October 2003.
