4. Fuel Injection System
4-24
Roll over sensor
Functional Description:
● Control power of the power relay coil, has the three-pin socket.
● When vehicles tilt angle greater than 65 degrees, roll over sensor will
be the implementation of ECU system power off. At this point once
again to restart the engine, the need to re-open a main switch.
● This as a safety device, when the dumping of vehicles, be cut off
power supply of ECU, and engine stop.
Testing Procedures:
● Because of the roll over sensor for the electronic control agencies, not
against removed after a single measurement.
● Normal state, after power is turned on the main switch, measurement
of ECU power relays red / yellow line to the Green Line (ground), the
power supply voltage measurement can determine whether it is normal
for the roll over sensor.
Detection judge:
Voltage: Supply voltage = Battery voltage
Treatment of abnormal phenomena:
Vehicle state vertical, power relays or ECU without electricity supply.
● Roll over sensor internal short circuit or open circuit, or coupler bad
contact.
● Check whether the abnormal wire harness lines.
● Roll over sensor anomaly, the proposed replacement of the roll over
sensor.
