System Operation
ECM Diagnostic Lamp
The ECM Diagnostic is used to indicate the existence of a diagnostic code. When a fault or event occurs, this lamp flashes a code pattern which is unique to that fault or event. It will continue to "flash" as long as the fault is ACTIVE. The ECM can sink 300 mAmp current to drive a lamp or buzzer.
On power up (key ON, Engine OFF), the lamp comes on for five seconds, then goes out. After this time, active diagnostic codes will be flashed out.
