DORSODURO 1200 ABS - ATC
Speed sensor
VEHICLE FRONT SPEED SENSOR
FUNCTION:To indicate the vehicle speed by read-
ing the front wheel turning speed.
OPERATION / OPERATING PRINCIPLE:Magne-
toresistive sensor: a square-wave pulse is gener-
ated with voltage approx. between 11.55 V and
11.25 V
WIRING DIAGRAM Level in wiring diagram: ABS.
REMOVAL
LOCATION ON THE VEHICLE:on the fork, right
stem, next to the brake calliper support.
CONNECTOR LOCATION (if available): under
the helmet compartment.
PINS
•
PIN 1- Ground connection (white)
•
PIN 2 - Power supply voltage/Output
signal (white/brown)
NAVIGATOR
Parameters: Speed (km/h) - Vehicle speed.
ELECTRICAL ERRORS
Speed sensor
5D90 electric malfunction: Electrical fault in sensor or cable harness.
Troubleshooting: Check the sensor connector and the ABS control unit connector. If they are not OK,
restore the connectors. If they are OK, check continuity of the white/brown cable between PIN 2 of the
sensor on the cable harness side and PIN 14 of the ABS control unit connector. If there is no continuity,
restore them. If there is, PIN 2 of the sensor on the cable harness side, with the sensor disconnected
and key set to ON, must have 12V voltage approximately: if there is no voltage, check PIN 2 for continuity
with the vehicle ground connection: if it is grounded, restore the cable harness. If OK, replace the control
unit. If PIN 2 has approx. 12 V, check the continuity of the white cable between PIN 1 of the sensor on
the cable harness side and PIN 13 of the ABS control unit connector. If there is no continuity, restore
the cable harness. If there is, replace the logic errors sensor.
LOGIC ERRORS
