Yamaha Tenere 700 2020 Service Manual page 412

TIP
The ABS performs a self-diagnosis test for a few seconds each time the vehicle first starts off after the
main switch was turned to "ON". During this test, a "clicking" noise can be heard from hydraulic unit,
and if the brake lever or brake pedal are even slightly applied, a vibration can be felt at the lever and
pedal, but these do not indicate a malfunction.
Self-diagnosis using the ABS ECU
The ABS ECU performs a static check of the entire system when the main switch is turned to "ON". It also
checks for malfunctions while the vehicle is ridden. Since all malfunctions are recorded after they are detect-
ed, it is possible to check the recorded malfunction data by utilizing the Yamaha diagnostic tool when the
ABS ECU has entered the self-diagnosis mode.

NOTICE
Care should be taken not to damage components by subjecting them to shocks or pulling on
them with too much force since the ABS components are precisely adjusted.
• The ABS ECU and hydraulic unit are united assemblies and cannot be disassembled.
• The malfunction history is stored in the memory of the ABS ECU. Delete the fault codes when the ser-
vice is finished. (This is because the past fault codes will be displayed again if another malfunction
occurs.)
