Bank Angle Sensor - APRILIA SL 750 SHIVER Service Station Manual

SL 750 SHIVER

Bank angle sensor

FALL SENSOR
Function
it tells the vehicle position to the control unit.
Operation / Operating principle
When the sensor is inverted, the circuit is closed
to ground: When the Marelli control unit detects
this ground connection, it does not enable start-up
or shuts off the engine.
Level in wiring diagram:Start-up enabling
switches.
Location:
•
on the vehicle: under the saddle
•
connector: near the sensor
Electrical characteristics:
•
Sensor in vertical position: open circuit
(resistance: 62 kOhm)
•
Sensor inverted: closed circuit (con-
tinuity)
Pin-out:
1. Ground connection
2. Voltage 5V
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL CON-
CEPTS OF ELECTRICAL TROUBLESHOOTING FOUND AT THE BEGINNING OF THE CHECKS
AND CONTROLS SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
AXONE: PARAMETERS
Fall sensor
Example value: Normal / Tip over
Indication on Axone always Normal, even when the sensor is inverted: disconnect the connector and,
with sensor inverted, check if there is continuity between the two PINS of the sensor: if there is no
continuity, replace the sensor; if there is, check the connector. If not OK, restore the cable harness; if
OK, check continuity to ground of PIN 1: if there is no continuity, restore the cable harness; if there is,
with key set to ON, check if there is 5V voltage at PIN 2. If there is not, check the Marelli control unit
connector (ENGINE connector PIN 8).
Indication on Axone always Tip over: disconnect the connector and check if there is continuity between
the two PINS when the sensor is in vertical position: if there is continuity, replace the sensor; if there is
