DTC stored in Engine
Control Module (ECM)

This malfunction only
occurs if vehicle is
equipped with ASR. Data is transferred between ABS
control module -J104- and Engine
Control Module (ECM) via a single
wire or via the CAN-bus. For more information, see the section "Systems
related to ASR" page 01
-42
and the table "Control
module versions" page 01-134
.


A DTC was stored in the Engine
Control Module (ECM). The Engine
Control Module (ECM) is not able to
reduce engine torque. - Check DTC memory of Engine Control Module
(ECM). Repair the malfunction according to the
appropriate engine Repair Manual and erase DTC
memory of the Engine Control Module (ECM).
