Electrical Connectors
Before beginning any diagnosis, the following connector
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.
• Broken or bent cable pins within multi-
plugs.
For example, the electronic control module (ECM) relies
on the supply of accurate information to enable it to plan
the correct fueling and ignition timing. 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 Disconnection:
• 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.
When Disconnecting a Connector:
• Check for a security device that must be
released before the connector can be
separated. E.G. barb, hook and eye etc.
When Inspecting a Connector:
• 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.
• Push together squarely to ensure terminals
are not bent or incorrectly located.
• Push the two halves together positively.

Disconnection of ECM connectors
Note:
• Two different coloured and shaped
connectors are used in the ECM, which
ensures correct connection is always made.
The connectors on the ECM are coloured
black and grey, and correspond with
identical coloured connectors on the main
harness.
A
Caution
When disconnecting a connector, never pull directly on
the wires as this may result in cable and connector
damage.
ACaution
Never disconnect the 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.
1. Turn the ignition to the 'OFF' position and wait at
least 1 minute for the ECM to complete its power
down sequence.
2. Press down on the locking device and gently pull
back on the connector to release it from the ECM.

Note:
• The ECM is located beneath the fuel tank,
on the upper section of the airbox.
