DIAGNOSIS PRECAUTIONS
? Before performing the trouble diagnosis, always read the general information (GI) to confirm the general
precautions. Refer to GI-4, "
General Precautions" .
? After completing service, always erase the self-diagnosis results. Refer to BRC-20, "ERASE MEMORY" .
? When inspection of the continuity or voltage between units is performed, check connector terminals for
disconnection, looseness, bend, or collapse. If any non-standard condition is detected, repair or replace
applicable part.
? Intermittent errors may be caused by a poor connection in the harness, connector, or terminal. Move har-
nesses, harness connectors, or terminals by hand to make sure all connections are solid and undamaged.
? If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
? ABS is a system that uses electronic control to perform brake control and engine power control. There-
fore, phenomena like those shown in the following table may occur, but this is because the system is
working normally.
