Yamaha 2008 Fazer FZ1-N Service Manual page 475

Differences between the normal handling and services on a vehicle
• Care should be taken not to damage components by shocks and pulling too much since the ABS
components are precisely adjusted.
• ABS ECU, HU, Wheel sensors and ABS motor relay cannot be disassembled.
• Malfunction history in ABS ECU is recorded. Delete it when the service is finished. (This is
because the past malfunction contents will be redundantly displayed when the same malfunction
occurred again.)
