(yellow/brown)
DIAGNOSIS INSTRUMENT
Parameters:
Speed (km/h) - Rear wheel speed
DIAGNOSIS INSTRUMENT: ELECTRICAL ERRORS
C1004 Rear speed sensor: short circuit.
It activates when the two wires are shorted one with the other or if the negative wire is shorted to positive
(e.g. 12V).
Troubleshooting:
Check insulation of yellow cable and yellow/brown cable: if NOT OK, restore cable harness; if OK, check
positive insulation (12V) of the yellow cable. If NOT OK, restore; if OK, check with sensor disconnected
and key ON that power voltage is slightly below battery voltage. If OK, replace the sensor; if NOT OK,
replace the CLF control unit.
C1005 Rear speed sensor: electric malfunction.
Missing sensor or interrupted wire or short circuit to negative of one of the two wires.
Troubleshooting:
Check the sensor connector and the CLF control unit connector. If it is not OK, restore the connectors;
if it is OK, check continuity of the yellow/brown cable across wiring-side sensor PIN 2 and PIN 4. If NOT
OK, restore cable harness; if OK, check the continuity of the yellow cable across wiring-side sensor PIN
1 and CLF control unit connector PIN 5. If NOT OK, restore cable harness; if OK, check the yellow/
brown cable ground insulation. If NOT OK restore cable harness; if OK, check the yellow cable ground
insulation. If NOT OK restore cable harness; if OK, check with sensor disconnected and key ON that
power voltage is slightly below battery voltage. If OK, replace the sensor; if NOT OK, replace the control
unit
CLF C1009 Rear speed sensor: electric malfunction.
It activates when the positive wire is shorted to ground.
Troubleshooting:
Check continuity of yellow/brown cable across wiring-side sensor PIN 2 and CLF connector PIN 3: if
NOT OK, restore cable harness; if OK, check ground insulation of the yellow/brown cable. If NOT OK,
restore cable harness; if OK, check with sensor disconnected and key ON that power voltage is slightly
below battery voltage. If OK, replace the sensor; if NOT OK, replace the CLF control unit.
