The Cylinder Identification (CID) sensor can light the MIL with no Continuous Memory codes present. This occurs when an intermittent ignition
system fault is present long enough to activate the MIL, but then goes away. The CID sensor can indicate that the CID fault may not register if the
fault goes away fast enough.
14.
Intermittently Open Self-Test Input (STI) Circuit
If the Self-Test Input (STI) circuit has an open during the KOEO self-test of code outputs, Continuous Memory will be cleared.
15.
Power Loss to EEC Processor
In some cases, the processor can lose power while the MEL stays powered. The MEL can light if a ground path is present through the processor.
16.
Other Warning Lamps Mistaken for MIL
The MIL can sometimes be confused with other warning lights that are located near it on the dash.
17.
Development Testing of Wrong Processor Released to Production
The MIL can be lit without Continuous Memory codes during development testing, or if the wrong processor is released to production.
