EN GI N E CON T ROL M ODU LE
DESCRIPTION
The electr onic con trol module (ECM) is mou nted t o
the left lower dash panel an d consists of an elect ronic
pr inted circuit board which is designed as a milliliter
board assembly fitted on both sides. The routing of
the wiring harn ess con nector at t he ECM connector
are split into in terferin g ca bles and sensitive cables
in order to ach ieve improved electromagnet ic compat-
ibilit y. The smaller wiring harness connect or is used
for the vehicle wiring harness and the larger ha rness
is used for the en gin e wir ing harness. The ECM
st ores engine specific da ta, monitors the connected
sensor and a nalyzes their mea su remen t (Fig. 2).
It s ta sk consists in cont rolling t he following sys-
tems in lin e wit h the a nalysis of the input signa ls:
• Fuel Supply System
• Injected Quantity Cont rol
• Emission Contr ol System
• Ch arge Pr essu re Cont rol
• Cr uise Control
• A/C Compressor Shu t-Off
• Pre-Hea tin g Out pu t Relay for the Glow P lugs
• Vehicle Theft
• Air Bag
• Mon itor s in pu ts/outpu ts, ch ecks plausibility and
st ores fau lts
• Share inform ation with ot her control modules
• Diagnosis
If a sensor should fa il, provided the fault is not
seriou s, the ECM will continu e to operate the engine
in Limp-Home Mode (emergen cy mode) using a
default value for the missin g signa l. The ECM
ensures that, cont inuing to operate the engine will
not cause damage or effect sa fety, otherwise a Engin e
sh ut-off process will be ca rried out (Fig. 3).
