Check cable continuity:
- ABS ECM connector pin 17 and
wheel speed sensor connector pin 1
(motorcycle harness side)
Locate and rectify wiring
harness fault, proceed to
test 9
Reconnect the front wheel speed sensor
connector. Check the wheel speed
sensor operation:
- -Connect a suitable voltage supply
between 10 V and 16 V between ABS
ECM connector pin 8 (positive) and
pin 17 (negative), and measure the
current consumption of the wheel
speed sensor
Replace the wheel speed
sensor, proceed to test 9
Reconnect ABS ECM harness, clear fault
code and test ABS to verify fault cleared.
Action complete - quit test
