Diagnostic Lamp
The electronic control module provides an output that activates a diagnostic lamp. If the electronic control module detects an active diagnostic condition, the diagnostic lamp will produce a series of flashes.
The flashes represent two digit diagnostic flash codes. The flash codes perform the following functions:
- Alert the operator to the presence of active diagnostic conditions.
- Indicate the nature of the conditions.
If a flash code is generated, investigate the condition and correct the problem as soon as possible. Correcting the problem will shut off the diagnostic lamp.
