Electrical system
VEHICLE REAR SPEED SENSOR
FUNCTION:To indicate the vehicle speed by read-
ing the rear 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 swingarm,
right side, under the chain tension screw.
CONNECTOR LOCATION (if available): under
the saddle, right side.
PINS
•
PIN 1- Ground connection (yellow)
•
PIN 2 - Power supply voltage/Output
signal (yellow/brown)
NAVIGATOR
Parameters: Speed (km/h) - Vehicle speed.
ELECTRICAL ERRORS
Speed sensor
5DA0 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 yellow/brown cable between PIN 2 of the
sensor on the cable harness side and PIN 11 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 continuity of the yellow cable between PIN 1 of the sensor on the
cable harness side and PIN 12 of the ABS control unit connector. If this is not OK, restore the cable
harness. If it is OK, replace the sensor.
LOGIC ERRORS
Speed sensor
5DA1 the signal works irregularly:faulty sensor or signal interference.
Troubleshooting:Check speed sensor retainer. If it is not OK, restore it. If it is OK, check if the tone
wheel is dirty, deformed or wrongly fixed. If any of this happens, replace the tone wheel. Otherwise,
replace the speed sensor.
