Fault Indications
If 'range' figures at 100% are seen, then the adjustment has reached maximum indicating
a mechanical fault exists on the motorcycle. This can be due to a number of faults but
the most likely causes will be low/high fuel pressure, faulty injectors or air leaks at the
throttle bodies or airbox.
In these circumstances, locate and rectify the fault, and reset the adaptions as described
above.
Diagnostics and Testing
Electrical Connectors
Before beginning any diagnosis, the following connector related information should be
noted:
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 multiplugs.
For example, the electronic control module (ECM) relies on the supply of accurate
information to enable it to plan the correct fuelling 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.
