Clear Fault Codes
Active fault codes are cleared when the problem is repaired. KAM faults are
automatically cleared as a consequence of reading the fault code. Therefore it is
important that the faults are recorded during the test.
Disconnecting the vehicle battery will also erase any codes stored. This may result in
surging engine speed, lumpy idle, hesitancy and poor driveability. When the battery
is reconnected:
• Allow engine to idle for three minutes.
• Wait until the engine reaches normal operating temperature.
• Raise the engine speed to 1200 rpm and hold for two minutes.
• Drive the vehicle for five miles under a variety of road and traffic conditions.
2- Digit Systems Without KAM (2.8i & 2.0i) and IAW Systems
Active fault codes only are available on this system. Any faults are cleared when the
ignition is switched off. Before reading fault codes, allow the vehicle some time to
determine whether any faults are present for both ignition on, engine off and with
engine running.
The user will be asked to crank the engine if the engine will not start. This is for the
system to test the vehicle components.
