Diagnostic lamp (Pin 2)

The diagnostic lamp, figure 27 alerts the operator
to the presence of an active diagnostic code. A
diagnostic code indicates a fault condition in the
electronic control system. The operator uses this
indication to help diagnose component failures in
the electronic control system. The diagnostic flash
codes should only be used to indicate the nature
of the occurrence of a diagnostic condition. The
flash codes should not be used to perform detailed
troubleshooting. Troubleshooting should be performed
using diagnostic codes that are displayed by using an
electronic service tool.
When the ECM is energized (keyswitch turned ON),
the warning lamp will turn on for five seconds. Then
the lamp will turn off unless the ECM detects a warning
condition.
