Diagnostic step

NOTICE

• To implement the following steps, ensure that ABS/ESP is grounded properly.
• Before conducting electric diagnosis, do refer to the reference circuit diagram
and the element information.

• Before conducting measurement, check the pins of connectors for rupture,
looseness and rust, and ensure that the pins are contacted properly.
• If the connection is good, check the sensor signal voltage when moving the
connector and harness. If a fault occurs, the voltage display on the diagnostic
instrument will change.
