Precautions for vehicle ECU operation
When performing diagnostic operations on a vehicle equipped with the ECU,
pay attention to the following items:
When the ignition switch is turned on, the vehicle internal electrical units
must not be disconnected. Otherwise, a high instantaneous voltage will
be generated due to the self-inductance of the coil, which will cause
damage to the sensor and ECU.
Do not place magnetic objects such as radio speakers close to the
computer, because the speaker magnets can damage the circuits and
components in the ECU.
Do disconnect the ECU system power supply when welding on the
vehicle.
When performing repair work near a computer or sensor, pay more
attention to avoiding damage to the ECU and sensor.
