the following: a) ABS control unit connector, b) inertia sensor platform (Sensor box) con-
nector and check the continuity across inertia sensor platform (Sensor box) connector pin
2 and ABS control unit connector pin 11. If NOT OK, replace the vehicle cable harness; if
OK, check the continuity across inertia sensor platform (Sensor box) connector pin 3 and
ABS control unit connector pin 2. If NOT OK, change the cable harness; if OK, check for the

66 and 80 of the Marelli control unit vehicle connector, if NOT OK restore, if OK with key off
disconnect the ABS control unit connector, if NOT OK replace cabling, if OK check correct
power supply pin 18 (12V) and ground at pin 1 of the ABS control unit, if NOT OK restore
cabling, if OK replace the ABS control unit
•
Configuration error - Open the diagnostic tool devices status page to check if the control unit
setting is actually consistent with the motorcycle setting. Example: if the bike has an ABS
control unit the correct state that should be found in the diagnostic tool device status screen
will be: MGTC (traction control) PRESENT. In the event of a bike with ABS control unit
