Introduction
Changes from the previous issue
The changes made in this document compared with the previous issue are marked
with a line in the left-hand margin. The changes are also described below.
• Information about harness-to-harness connectors C4125 and C4126: Throttle
control for Stage V engines has been added to section Engine interface.
• The requirements for the electrical cables for OC16 ignition coils have been clar-
ified in section C4094: Harness-to-harness connectors for ignition coils and throt-
tle actuator at gas mixer.
Different requirements
For PDE engines, except marine engines with PDE and SCR systems, engine control
unit S6 is used. For XPI engines and marine engines with PDE and SCR systems, en-
gine control unit S8 is used. 16 litre gas engines use engine control unit OCE1.
There are two different requirements for the electrical installation of S6 and S8: with
or without Scania's base system. This installation manual does not describe Scania's
electrical systems. Information about these can be found in
• 03:04 Instrumentation 2.1.
• 03:03 Instrumentation 2.0.
• 03:02 Coordinator and base system.
Grounding
In this document the term ground is used. Ground means that there is a connection to
the battery negative terminal.
