Precaution
Turn the ignition switch off before measuring the
resistance of the main wire and the branch wire.
After the ignition switch is turned off, check that the

Measure the voltage and resistance of the
connectors.
Hint:
Check from the rear of the connector while it is
connected to the air conditioning amplifier.

Inspection procedure
Notice:
When replacing the abs and traction actuator, perform the zero point
calibration (see page bc-

Check for intermittent problems
Hint:
Inspect the vehicle's ecm using check mode. Intermittent
problems are easier to detect with the intelligent tester when
the ecm is in check mode. In check mode, the ecm uses 1
trip detection logic, which is more sensitive to malfunctions
than normal mode (default), which uses 2 trip detec ...
