Troubleshooting Section
Use the lamps to check the engine's
operational status or the existence
of any engine faults.
Each lamp will be illuminated in a combination of
ways in order to identify the engine's operational
status. The lamps will also be illuminated in a
combination of ways to indicate if the engine has a
fault. These combinations of illuminated lamps have
the following meanings:
The status of the lamps before the engine is
cranked. This also acts as a lamp check.
When the ignition switch is turned ON, the lamps will
be illuminated for 2 seconds. The lamps are then
OFF unless the cold starting aid is required.

This is the status of the lamps while the engine
is being cranked.
Unless there is a fault, the engine monitoring system
will not illuminate the indicator lamps while the
engine is being cranked. For example if there is a
lack of lubricating oil pressure after the start delay is
exceeded. This type of fault will cause the stop lamp
for the engine to be illuminated.
