Why the ECM of the Car is Failed Suddenly

1
WHY THE ECM OF THE CAR IS FAILED SUDDENLY?
2
ECU refers to be the engine control unit of the
car that is also known as
3

• Power control module(PCM)
• Engine Control Module(ECM)

4
Thus, the ECM regulates an important system and
function in the car.
5
ECM can transmit data feedback to the engine
through various medium such as
6

• Electronic sensors
• Components
• Chips

7
Lots of internal causes could malfunction the ECM
in the first place.
8
Here is the list of causes that may fail the ECM
of the car suddenly.
9
One can check the voltage amount of the ECM
through its wiring harness.
LOWER VOLTAGE
10
If the voltage is not lying between 6 to 12
volts, then it is causing the ECM problem.
11
Override sensor in the starter is managing the
volts receiving by the ECM.
DAMAGED STARTER
12
If the sensor is damaged, then the ECM unable to
receive the correct amount of voltage.
13
Batteries of the car have electronic cells for
the ECU to function.
FAILED BATTERY
14
If any cells of the battery are failed, then the
ECM is going to fail soon.
15
Ensure that the jumper cable is attached properly
while performing the battery jump start.
ISSUES IN JUMP-STARTING
16
Incorrectly attached cable could short out the
ECM by spike it too quickly.
17
ECM of the car have seals to prevent moisture
from entering the engine.
CORRODED SEALS
18
If the seals become worn, the moisture easily
passes through it and damage ECM components.
19
To protect the ECM of the car, you have to
consider the causes behind the issues.
CONCLUSION
20
Consult with a certified mechanic for fixing the
issues as early as possible.
