related information should be noted:
Note:
A major cause of hidden electrical faults can be
traced to faulty electrical connectors.
For example:
Dirty/corroded terminals.
Damp terminals.

• B
ken or bent cable pins within multi-plugs.
For example, the ABS electronic control module (ABS
ECM) relies on the supply of accurate information to
enable it to monitor and control the brake system. One
dirty terminal will
cause an excessive voltage drop
.
resulting in an incorrect signal to the ECM.
If, when carrying out fault diagnosis, a fault appears to
clear by simply disconnecting and reconnecting an
electrical plug, examine each disconnected plug for the
following.
Before Dsconnechon:
• If testing with a voltmeter, the voltage
across a connector should be virtually
battery volts (unless a resistor is fitted in the
circuit). If there is a noticeable : change,
suspect faulty/dirty connections.
a Connector:
When Disconnecting
• Check for a security device that must be
released . before the connector ' can be
separated. E.G. barb, hook and eye etc.
Inspecting a Connector:

4 Check that the individual pins have not been
bent.
Check for dampness/dirt/corrosion.
• Check cables for security.
• Check cable pin joints for damage.
When Connecting a Connector.
• Ensure there is no dirt around the
connector/seal.

When disconnecting a connector, never pull directly on
the wires as this may result in cable and connector
damage.
Never disconnect the ABS ECM when the ignition
switch is in the 'ON' position as this may cause multiple
fault codes to be logged in the ECM memory.
Always disconnect an ECM after disconnecting the
battery negative (black) lead first.

Lift up the locking device and gently pull back on the
connector to release it from the ECM.
• The ABS ECM is an integral part of the ABS
modulator. Under no circumstances should
the ECM be removed from the ABS
modulator. If a new ECM is required, repair
is by replacement of the ABS modulator and
ECM as an assembly only.
