3.5.1 ECU
3.5.1.1 Description & Working Principle
The ECU continuously monitors the operating conditions of the engine through the system
sensors. It also provides the necessary computation, adaptability, and output control in order to
minimize the tailpipe emissions and fuel consumption, while optimizing vehicle drivability for all
operating conditions. The ECU also provides diagnosis when system malfunctions occur.
3.5.1.2 Appearance
The MT05 ECU has a polyester header, with an aluminum base plate. The ECU is shown
below.
3.5.1.3 Handling –Don'ts & Do's
DO NOT: Place the ECU close to the exhaust pipe
or Engine when removed.
DO NOT: Place the ECU close to or pour water, oil
or any other liquids.
DO NOT: Allow mud or other debris to accumulate
on the surface of the ECU.
DO NOT: Apply any voltage relative to any point to
the ECU.
DO NOT: Clean ECU with any solvent or any
corrosive liquid.
DO: Take extreme care that water droplets or
excess moisture should not fall on ECU connectors.
DO: Clean the ECU with a moist cloth and keep it
dry.
3.5.1.4 Installation requirements
The ECU shall be mounted using M6 machined screws with a torque of 8 Nm ±10%. The
mounting surface should also be flat to avoid subjecting the base plate to unnecessary force and
warping the PCB.
ACTION
T-Boss550 SERVICE MANUAL20.0
REASON
High temperature might reduce the life of the ECU
and also can damage the ECU.
ECU is susceptible to water and liquids
Having mud or debris accumulated on the ECU
casing reduces its heat dissipation efficiency.
Drastically affects the performance of the ECU and
may lead to ECU damage.
Can damage the housing of the ECU.
ECU connectors can get short and may lead to ECU
damage.
Prevents ECU damage.
