Inducement Strategy Of Ats System - Kohler KDI-TCP 3404 E5 Owner's Manual

2.8 Inducement strategy of ATS system

The inducement is the operation aimed at reducing the engine performance due to a malfunction or tampering with
the ATS system detected by the DCU.
The inducement degree is decided by the ECU according to the error detected by the DCU.
The information on the car panel or the activation of the inducement can occur for the following reasons:
•
Low AdBlue®/DEF level
•
®
Poor AdBlue /DEF quality
•
Interruption of AdBlue
•
EGR valve malfunctioning
•
Tampering with the monitoring systems of the ATS system.
The inducement strategy is applied according to:
•
detected problem
•
hours passed.
NOTE: Hours are reset after 40h if the DCU does not detect any fault, otherwise the hours are added to those
already counted. For low AdBlue®/DEF level, activation depends on the percentage of liquid inside the
AdBlue®/DEF tank, and the fault hours are not counted.
The strategy for the different faults is listed below (Stage V - EU):
The inducement can have the following 2 levels:
•
Level 1: 25% reduction of the MAX available torque.
•
Level 2: 50% reduction of the MAX available torque and 40% reduction of MAX rpm available.
Before activating the inducement (level 1 or level 2) the ECU activates a warning or a warning light on the car panel
(refer to the car documentation for the warning type).
Low AdBlue®/DEF level
•
information activation on car panel: <10% of MAX level
•
Level 1 inducement: <2.5% of MAX level
•
Level 2 inducement: 0% of MAX level
Poor AdBlue®/DEF quality
•
information activation on car panel: upon fault detection
•
Level 1 inducement: after 10h from fault detection
•
Level 2 inducement: after 20h from fault detection
Interruption of AdBlue®/DEF supply
•
information activation on car panel: upon fault detection
•
Level 1 inducement: after 10h from fault detection
•
Level 2 inducement: after 20h from fault detection
EGR valve malfunctioning
•
information activation on car panel: upon fault detection
•
Level 1 inducement: after 36h from fault detection
•
Level 2 inducement: after 100h from fault detection
