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.
