NOTE:
THIS TECHNICAL SERVICE BULLETIN WILL BE UPDATED AS OTHER MODELS INCORPORATE THIS FEATURE.
DISCUSSION:
A new feature (Customer OBD Inspection/Maintenance (I/M) Readiness) which utilizes the OBD MIL (Malfunction Indicator Lamp) has been implemented to provide customers with the capability to determine if their vehicle is "READY" for an I/M test.
NOTE:
PASSING I/M READINESS MAY BE REQUIRED BY SOME STATES AS A PRE-REQUISITE FOR VEHICLE REGISTRATION.
This change is reflected in the way the MIL illuminates during key "ON" (no crank/start) as follows:
1. Switch ignition to the "ON" position. Do not crank or start the engine.
NOTE:
IF THE ENGINE IS CRANKED OR STARTED, THE PROCEDURE MUST BE RESTARTED FROM KEY "OFF".
2. The MIL will illuminate (bulb check) and will continue to illuminate for approximately 15 seconds. After 15 seconds, one of the following two conditions will occur.
NOT READY FOR AN I/M TEST
The MIL will flash once per second for approximately 10 seconds and then return to a fully Illuminated condition until the ignition is turned "OFF" or the engine is started.
READY FOR AN I/M TEST
The MIL will continue to illuminate until the ignition is turned "OFF" or the engine is started.
MIL functionality during normal (engine running) vehicle operation remains unchanged.
