Bank Angle Sensor - MOTO GUZZI 1200 SPORT 4V ABS Service Station Manual

1200 SPORT 4V ABS

Bank angle 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
earthing, it disables the fuel pump circuit and the
engine start-up circuit via the injection relay.
Level in wiring diagram:Start-up enabling
switches.
Location:
•
Sensor: close to the headstock
•
Connector: near the sensor
Electrical characteristics:
•
Sensor in vertical position: open circuit
(resistance: 62 kOhm)
•
Sensor inverted: closed circuit (resist-
ance below 0.5 kOhm)
Pin-out:
•
PIN 1: Voltage 12V
•
PIN 2: Ground connection
AXONE: STATUSES
Fall sensor
Example value: Normal / Tip over
DIAGNOSIS
•
Indication on Axone always Normal, even when the sensor is inverted: disconnect the con-
nector 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 2: if there is no
continuity, restore the cable harness; if there is, with key set to KEY ON, check if there is
12V voltage at PIN 1. If there is not, check the Marelli control unit connector (PIN 35 of the
BLUE connector)
•
Indication on Axone always Tip over: disconnect the connector and check if there is con-
tinuity between the two PINS when the sensor is in vertical position: if there is continuity,
replace the sensor; if there is not, it means that, with key set to KEY ON, there is no 12V
voltage at PIN 1: restore the cable harness whose pink/yellow cable will be shorted to ground
