WITH COLOR DISPLAY : Trouble Diagnoses for Abnormal Pressure
Whenever system′s high and/or low side pressure is abnormal, diagnose using a manifold gauge. The marker above the gauge scale in the following tables indicates the standard (usual) pressure range. Since the standard (usual) pressure, however, differs from vehicle to vehicle, refer to above table (Ambient air temperatureto- operating pressure table).
Both High- and Low-pressure Sides are Too High
High-pressure Side is Too High and Low-pressure Side is Too Low
High-pressure Side is Too Low and Low-pressure Side is Too Hig
Both High- and Low-pressure Sides are Too Low
Low-pressure Side Sometimes Becomes Negative
Low-pressure Side Becomes Negative

AV branch line circuit
Diagnosis Procedure
1.CHECK CONNECTOR
Turn the ignition switch OFF.
Disconnect the battery cable from the negative terminal.
Check the terminals and connectors of the AV control unit for
damage, bend and loose connection (unit
side and connector side).
2.CHECK HARNESS FOR OPEN CIRC ...
C1142 press sen circuit
Description
The pressure sensor converts the brake fluid pressure to an electric signal
and transmits it to the ABS actuator
and electric unit (control unit). (The pressure sensor is integrated in the ABS
actuator and electric unit (control
unit).)
